The gradient moves behind the shakes (see Figure 11.17). Don’t worry about the gradient boundaries; they won’t appear when the drawing is plotted.

14. Save this drawing as 11A-FPLAY2.dwg.

using Hatches in the Floor Plan In the floor plan, you can use hatches to fill in the walls or to indicate various kinds of floor surfaces. You’ll start with the floors.

Hatching the Floors So far, you’ve used only predefined hatch patterns—the 69 patterns that come with AutoCAD. You can also use a user-defined pattern, which is a series of par- allel lines that you can set at any spacing and angle. If you want to illustrate square floor tile, select the Double option of the user-defined pattern, which uses two sets of parallel lines—one perpendicular to the other, resulting in a tiled effect.

Creating the user-Defined Hatch Pattern

You’ll use the user-defined pattern for a couple of rooms and then return to the predefined patterns. Follow these steps:

1. With 11A-FPLAY2 open, zoom into the floor plan and thaw the Headers and Fixtures layers.

C h a p t e r 11 • Wo r k i n g w i t h H a t c h e s , G r a d i e n t s , a n d To o l P a l e t t e s5 7 4

You can use the header lines to help form a boundary line across an entryway to a room and to keep the hatch pattern from extending to another room.

2. With the floor plan in full view, freeze the A- ROOF and A-ANNO-TEXT layers and then zoom into the bathroom.

Even if the rooflines are dashed, they will still form a boundary to a hatch.

3. Create a new layer called A-FLOR-PATT. Assign it color 142, and make it current.

4. Start the HATCH command to load the contextual Hatch Creation tab.

5. Change the Hatch Type to User Defined from the drop-down on the Properties panel of the contextual Hatch Creation tab.

After you choose User Defined as the Hatch Type, USER is selected as the current pattern in the Pattern panel, and the Scale text box in the Properties panel is replaced by the Hatch Spacing text box.

6. In the Hatch Spacing text box, change 1″ (1) to 9(229). Next, expand the Properties panel and click the Double button (see Figure 11.18)

F i G u R E 1 1 . 1 8 Defining the hatch pattern

7. Back in the drawing, be sure no osnaps are running, and use the auto- matic preview to pick two points to match the tiled hatch pattern shown in Figure 11.19.

For the first point, pick a location in the bathroom floor area, not touching the fixture lines or the door. To finish the bathroom floor hatch, click the floor between the door swing and the door, being careful to not touch the door.

8. With the bathroom hatches in place, press ↵ to end the HATCH command. The tiled hatch pattern should fill the bathroom floor and stop at the header while not encroaching into the door or fixtures (see Figure 11.19).

U s i n g h a t c h e s i n t h e F l o o r p l a n 5 7 5

F i G u R E 1 1 . 1 9 The tiled hatch pattern in place

Note that the user-defined pattern has no scale factor to worry about. You simply set the distance between lines in the Spacing text box.

W A R N I N G If you can’t get the HATCH command to hatch the desired area, you might have left a gap between some of the lines serving as the hatch boundary. this can prevent autoCaD from finding the boundary you intend to use. Zoom into the areas where objects meet, and check to see that there are no gaps or increase the Gap Tolerance value on the expanded Options panel in the contextual hatch Creation tab.

Controlling the origin of the Hatch Pattern

Often, a designer wants to lay out the tile pattern such that the pattern is centered in the room or starts along one particular edge. For this project, the tiles are set to start in the center of the room and move out to the edges, where they’re cut to fit. You’ll change the hatch pattern’s origin to set this up in the kitchen:

1. Use the Pan and Zoom tools to slide the drawing up until the kitchen occupies the screen. Thaw the A-AREA-NPLT layer.

2. Turn Object Snap Tracking on (on the status bar), and set the Midpoint osnap to be running.

3. Start the HATCH command, and make sure User Defined is still selected as the Hatch Type.

C h a p t e r 11 • Wo r k i n g w i t h H a t c h e s , G r a d i e n t s , a n d To o l P a l e t t e s5 7 6

4. From the Properties panel, change the Hatch Spacing to 12(305), and verify that Double is selected by expanding the Properties panel.

5. Choose the Set Origin tool from the Origin panel of the Hatch Creation tab, and move your cursor back into the drawing area.

6. Use the running Midpoint osnap in conjunction with Object Snap Tracking; acquire the midpoint of the lower kitchen area line and the midpoint of the right-side kitchen area line. When the cursor is posi- tioned properly, two tracking lines and a tooltip appear (see the top of Figure 11.20).

This sets the origin of any subsequently created hatch patterns at the center of this room and you are prompted to Pick internal point:.

7. Similar to the way you hatched the bathroom, pick a point anywhere in the main floor area of the kitchen, and then pick a second point between the door swing and the door. After choosing the two points, press ↵ to end the HATCH command.

This places the hatch of 12″ (305 mm) tiles in the kitchen (see the bottom of Figure 11.20). Notice how the pattern is centered left to right and top to bottom.

Each time you change the origin, all subsequent hatch patterns will use the new setting as their origin. For most hatches, the origin isn’t important, but if you need to control the location of tiles or specific points of other hatch pat- terns, you can reset the hatch origin before you create the hatch by clicking Specify New Origin and then entering 0,0↵.

Finishing the Hatches for the Floors To finish hatching the floors, you’ll use a parquet pattern from the set of predefined patterns in the living room and another user-defined pattern on the two decks:

1. Use Pan and Zoom to adjust the view so it includes the living room.

2. Using the Off tool found on the Layers panel of the Home tab, select the wall header for the closet to turn off the A-WALL-HEAD layer.

3. Start the HATCH command, and change the Hatch Type to Pattern from the Properties panel of the contextual Hatch Creation tab.

4. Expand the Pattern panel on the contextual Hatch Creation tab, and select the AR-PARQ1 pattern.

5. Set the scale to 1 from the Properties panel,and verify that the angle is set to 0.

6. Move your cursor back into the drawing area, and use the automatic preview to display what your hatch will look like when inserted into the drawing. As you can see in Figure 11.21, the squares look a little small.

F i G u R E 1 1 . 2 1 The parquet hatch with its initial scale of 1

7. Return to the contextual Hatch Creation tab, and reset the Hatch Pattern Scale to 1.33.

8. Move your cursor back into the drawing area, pausing inside the liv- ing room area to see a preview of the hatch. This looks better; click to insert the parquet pattern, and press ↵ to end the HATCH command.

The parquet pattern is placed in the living room (see Figure 11.22).

9. Freeze the A-AREA-NPLT layer.

10. Start the HATCH command, and change the Hatch Type to User Defined from the Properties panel of the contextual Hatch Creation tab.

11. Expand the Properties panel and deselect the Double option, set the Hatch Angle to 90°, and Hatch Spacing to 6″ (152).

12. Choose the Set Origin tool from the Origin panel, and use the Endpoint osnap to pick the lower-left inside corner of the front deck.

13. Move your cursor anywhere inside the front deck area, pausing for a moment to see the automatic hatch preview display.

15. Repeat steps 8 through 12 on the back deck using the lower-right corner of the deck as the hatch origin.

16. The transition between the kitchen and the living room floor coverings isn’t as clean and evident as it could be. Draw a polyline with a width of 0 from the corner of the bathroom, perpendicular to the living room window opening and then directly to that window, as shown in bold in Figure 11.24.

17. Save the drawing as 11A-FPLAY3.

Modifying the Shape of Hatch Patterns The next exercise will demonstrate how hatches are associative. An associative hatch pattern automatically updates when you modify the part of a drawing that is serving as the boundary for the pattern. You’ll be changing the current draw- ing, so before you begin making those changes, save the drawing as it is. Then follow these steps:

1. Zoom out and pan to get the floor plan and the north and south elevations in the view.

2. Thaw the A-ANNO-TEXT, A-ROOF and A-AREA-NPLT layers. You’ll use the STRETCH command to modify the plan and two side elevations.

3. Turn on Polar Tracking from the status bar.

4. Start the STRETCH command by selecting the Stretch tool on the Home tab ➢ Modify panel.

5. Pick a point above and to the right of the stairway in the north elevation. Drag a window down and to the left until a crossing selection window lands between the two closet doors in the floor plan and ends below the cabin in the south elevation (see the left image of Figure 11.25). Click to complete the window. Then press ↵ to finish the selection process.

6. For the base point, choose a point in the blank area to the right of the selection and click.

C r e a t i n g a n d M a n a g i n g to o l p a l e t t e s 5 8 1

7. Move the cursor directly to the right of the point you picked; then enter 5′↵ (1524↵).

8. The living room and roof are now longer, and the hatch patterns have expanded to fill the new areas (see the right image of Figure 11.25).

9. Save this drawing as 11A-FPLA3A.dwg.

Hatches are a necessary part of many drawings. You’ve seen a few of the pos- sibilities AutoCAD offers for using them in plans and elevations.

Creating and Managing tool Palettes If you find yourself using particular hatch patterns over and over in various drawings, wouldn’t it be advantageous to have them available at a moment’s notice instead of setting them up each time? AutoCAD’s tool palettes let you do just that and more.

C h a p t e r 11 • Wo r k i n g w i t h H a t c h e s , G r a d i e n t s , a n d To o l P a l e t t e s5 8 2

Now you’ll go through the process of setting up a couple of palettes and customizing them to contain specific hatch patterns, blocks, and commands that are used with the cabin drawings. From these exercises, you’ll get the information you need to set up your own custom palettes.

Creating a new tool Palette You’ll create a new tool palette and then populate it with the blocks you’ve used so far in the cabin drawing:

1. Open the 11A-FPLAY3.dwg file and thaw the A-ROOF layer.

2. Click the Tool Palettes tool found on the View tab ➢ Palettes panel to display the Tool Palettes palette set on the screen.

3. Place the cursor on a blank space on the palettes, right-click, and choose New Palette, as shown in Figure 11.26.

A new, blank palette appears with a small text box on it.

F i G u R E 1 1 . 2 6 Creating a new tool palette

4. Enter Cabin Blocks↵ to name the new palette.

5. Open the DesignCenter by clicking its button on the View tab ➢ Palettes panel, by entering ADC↵, or pressing Ctrl+2 on the keyboard.

6. On the left side of the DesignCenter, click the Open Drawings tab, and then select the current drawing (11A-FPLAY3.DWG). Navigate to the

C r e a t i n g a n d M a n a g i n g to o l p a l e t t e s 5 8 3

11A-FPLAY3A drawing under the Folders tab or the Open Drawings tab. When you find it, click the plus sign (+) to its left. The list of drawing content types in it opens below the drawing.

7. Select Blocks from this list. Now the right side of the DesignCenter displays the six blocks in 11A-FPLAY3, either as small images or by name only.

8. Click the arrow on the Views button in the DesignCenter toolbar, and choose Large Icons as the view option to see a display like Figure 11.27.

F i G u R E 1 1 . 2 7 The DesignCenter with the Large Icons view enabled

9. Select A-DECK-RAIL and then hold down the Shift key and click GRID-V to select all six blocks. Click and drag the six blocks over to the Cabin Blocks palette.

Small images of the blocks appear on the new palette (see Figure 11.28), and they’re now available for any drawing. Simply drag a block off the palette onto the drawing. You can then fine-tune its location, rotate it, and so forth. Any layers used by the block are also brought into the drawing.

F i G u R E 1 1 . 2 8 The Cabin Blocks tool palette you’ve just created

C h a p t e r 11 • Wo r k i n g w i t h H a t c h e s , G r a d i e n t s , a n d To o l P a l e t t e s5 8 4

N O T E tool palette tools like blocks are dynamically linked back to the source DWG file. In this example, the five blocks you added to the Cabin Blocks tool palette are now available to any drawing, provided the 11A-FPLAY3.dwg file still exists in its original location. Moving or deleting the drawing will break the link, consequently breaking the tool palette tool as well.

10. Place the cursor on A-DOOR on the new palette, right-click, and then select Properties to open the Tool Properties dialog box.

It displays information about A-DOOR and provides a means to change many parameters (see Figure 11.29).

F i G u R E 1 1 . 2 9 The Tool Properties dialog box

11. Change the Description for the A-DOOR tool to “Use for 2′, 2′-6″, 3′, and 3′-6″ doors” so the tooltip will more accurately describe the block’s intended application (see Figure 11.29).

12. Close the Tool Properties dialog box, and then move your mouse over the A-DOOR tool to display its description.

Setting up a Palette for Hatches To create a palette for hatches, you’ll create and name a new palette using the same procedure as in the preceding section, but the hatches are assigned to the palette in a different way:

1. Right-click a blank space on the Cabin Blocks palette, choose New Palette, and then enter Cabin Hatches↵ in the text box.

C r e a t i n g a n d M a n a g i n g to o l p a l e t t e s 5 8 5

2. Zoom in on the south elevation of the cabin, and click the roof hatch to display a grip.

3. Move the cursor to a portion of the roof hatch that isn’t close to the grip, and then click and drag the hatch pattern over to the new pal- ette (see Figure 11.30).

F i G u R E 1 1 . 3 0 Copying the roof hatch to the new palette

4. When the cursor is over the palette and a horizontal line appears there, release the mouse button.

The roof hatch is now positioned on the palette and available for use in any drawing. Simply drag it off the palette and into the enclosed area in the drawing that you want to hatch with the pattern.

5. Place the cursor on the new swatch of AR-RROOF, right-click, and choose Properties. The Tool Properties dialog box opens (see Figure 11.31).

6. Change the name from AR-RROOF to Cabin Roof. Enter a description of what the hatch represents, such as “Cabin roof, south elevation,” as shown on the left in Figure 11.32,or“shakes.”

Notice that the hatch has the angle and scale used on the roof and that it’s also on the A-ELEV-ROOF-PATT layer. Use the slider at the left to view all the properties. Click OK to close the dialog box and update the palette (see Figure 11.32, right).

By using the Tool Properties dialog box, you can also give hatches color. You can place all the hatches that you’ve used for the cabin so far on the palette in

C h a p t e r 11 • Wo r k i n g w i t h H a t c h e s , G r a d i e n t s , a n d To o l P a l e t t e s5 8 6

the same manner. They retain the properties they had in the original drawing, but by using the Tool Properties dialog box, you can change those properties.

Creating a Palette for Commands Take a moment to look at a few of the sample palettes that come with AutoCAD, and check the properties of some of the items that you see. In addition to blocks

C r e a t i n g a n d M a n a g i n g to o l p a l e t t e s 5 8 7

and hatches, there are also command icons. These are placed on the palette in a slightly different way from blocks and hatches:

1. Right-click the Cabin Hatches palette in a blank area, and choose New Palette from the context menu.

2. Name the new palette Commands.

3. Use the Zoom and Pan tools to bring the kitchen floor plan into view.

4. Click to select a single wall line, and then drag it to the palette just as you dragged the hatches in the previous section.

This adds the A-WALL line to the Commands tool palette with the rather ambiguous name “Line.”

4. Right click on the Line tool you just added to the Commands palette, and choose Properties.

5. From the Tool Properties dialog box, enter A-WALL for the name, and enter Creates a new wall object on the A-WALL layer as the description (see Figure 11.33).

F i G u R E 1 1 . 3 3 Changing the name and description for the A-WALL command tool

6. Repeat the process outlined in steps 4 through 6 to drag several additional objects of various kinds onto the Commands palette (see Figure 11.34).

When you need to use one of these commands, click the icon on the palette.

F i G u R E 1 1 . 3 4 The Commands palette with four command icons

If you set the palettes to Auto-hide, they fold under the palette title bar. When you put your cursor on the bar, the palettes display and then hide a moment after your cursor moves off the palettes. To activate Auto-hide, right-click the palette title bar and choose Auto-hide from the context menu, or click the Auto-hide button under the X at the top of the palette’s title bar.

This has been a brief introduction to the palette feature. To become familiar with palettes so that you can use them as you find the need, experiment with the various options. Try right-clicking a blank portion of a palette and investigating the commands available on the resulting context menu. From this menu, you can delete any palette and you can copy and paste tools from one palette to another.

if You Would Like More Practice… If you would like to practice what you’ve learned in this chapter, here are a couple of extra exercises.

Creating the Hatch Patterns for the other Elevations To create your hatch pattern for the roof, make these changes and additions to 11A-FPLAY3.dwg:

1. Make the A-ELEV-WALL-PATT layer current.

I f Yo u Wo u l d L i k e M o r e p r a c t i c e … 5 8 9

2. Start the HATCH command.

3. Click the Match Properties button on the Options panel of the con- textual Hatch Creation tab, and then click the hatch pattern on either side of the pop-out in the south elevation.

This copies that hatch’s properties to the contextual Hatch Creation tab.

4. Change the Hatch Angle in the Properties panel of the Hatch Creation tab to 180.

5. Move your cursor to a point inside the wall in the north elevation to display the automatic preview. Assuming the hatch correctly fills the wall in the north elevation, click and press ↵ to insert the hatch and end the HATCH command.

6. Repeat the previous process, changing the rotation, pattern, and layer until all the hatches and gradients in the south elevation (except the roof pattern, which only appears in the north and south) appear in the other three elevations.

Make sure you’re on the correct layer when creating the new  hatches.

You’ll need to draw additional rectangles on the A-ELEV- SHAD-BNDY layer to constrain the new gradients. Use polylines to draw the boundaries in the east and west elevations.

Make sure Create Separate Hatches is selected when you create  the hatch patterns for the windows.

T I P as you hatch the east, west, and north elevations, try using the LAYMCUR command (called the Make Object’s Layer Current tool on the home

tab ➢ Layers panel). This command will allow you to select an object and set its layer current.

When you are done, the remaining elevations should look similar to those in Figure 11.35.

W A R N I N G When layers are added to a drawing after a named view is saved, you must select that named view in the View Manager dialog box and then click the Update Layers button to display the layers correctly when you set the view to current.

7. Set the UCS back to World, and use the PLAN command to reorient the drawing area.

8. Save this drawing as 11A-FPLAY4.dwg.

Creating Your Hatch Palette It’s true that you can use any hatch pattern to represent anything you want, but most professions follow some sort of standard, even if loosely. The ANSI31 pat- tern of parallel lines is probably the most widely used pattern. Although accord- ing to the ANSI standard, it “officially” represents iron, brick, and stone masonry, it’s universally accepted as a cross-section view of any material—that is, the part of the object that was sliced through to make the view.

In this exercise, you’ll create a new palette of hatches that you might use in your work. Use the same method demonstrated in the previous section of this chapter:

1. Open the DesignCenter. Under the Folders tab, find and select acad.pat. If you performed a typical installation of AutoCAD, the file should be in the C:\Program Files\AutoCAD 2011\UserDataCache\Support folder. LT users should substitute AutoCAD LT 2011 for AutoCAD 2011 in the path. Open that file.

2. Use the Large Icons view to view the patterns on the right side of the DesignCenter.

3. On the right side of your screen, create a new tool palette and name it Hatches.

4. Back in the DesignCenter, scroll through and drag any patterns you might use over to the new Hatches palette.

5. Close the DesignCenter.

6. Hold the cursor briefly over the name of each hatch to display a tool- tip that describes the name and purpose of the hatch.

7. If you’ve brought any patterns to the palette that you don’t want there, right-click each of them and choose Delete from the context menu.

Don’t worry about changing any of the properties, such as Scale or Rotation. That will come later, as you begin to use these hatches in your own work.

8. Check out the tools on the Hatches And Fills sample palette that comes with AutoCAD.

To access a list of all the available sample palettes, move the cur- sor over to the tabs that identify each palette. Then move it down just below the lowest tab where you see the edges of the tabs that are

C h a p t e r 11 • Wo r k i n g w i t h H a t c h e s , G r a d i e n t s , a n d To o l P a l e t t e s5 9 2

hidden. Click the edges of the hidden tabs, and choose a palette from the list to be brought forward and displayed as the top tab.

9. Right-click some of the hatches or fills, and note how the rotation and scale vary for hatches that look the same on the palette. One hatch, such as ANSI31, might be repeated several times on the same palette, with each occurrence having a different scale or rotation. Notice that the names of the hatches and fills have been removed from the sample hatch palette. Can you figure out how to do this in your own palette or how to store the names?

CHAPtER 12

Dimensioning a Drawing Dimensions are the final ingredient to include with your cabin drawing. To introduce you to dimensioning, I’ll follow a pattern similar to the one I used in Chapter 8, “Controlling Text in a Drawing.” You will first create a dimension style that contains the properties for the dimensions, and then you will add the dimensions themselves.

C h a p t e r 1 2 • D i m e n s i o n i n g a D r a w i n g5 9 4

introducing Dimension Styles Dimension styles are similar to text styles but give you more options to control. You set them up in the same way, but many parameters control the various parts of dimensions, including the dimension text.

Before you start setting up a dimension style, you need to make a few changes to your drawing to prepare it for dimensioning:

1. Open 11A-FPLAY4.dwg. This is the cabin with hatch patterns added to all the views. If you

didn’t complete the “If You Would Like More Practice” section in the previous chapter, you can download the file from the book’s website.

2. Create a new layer called A-ANNO-DIMS, assign color 7 (White), and make it current.

3. Freeze all the remaining layers except 0, A-ANNO-TEXT, A-DECK, A-DECK-STRS, A-DOOR, A-GLAZ, A-ROOF, A-WALL, and all of the A-ELEV layers without a -PATT or -BNDY suffix.

restor Ing the state oF MUlt Iple layers The Layer States Manager is an incredibly powerful tool that will allow you to restore the state of a large number of layers. Although it cannot create any layers, it can save, export, and import nearly every layer property found in the Layer Properties Manager palette. By default these are saved inside the DWG file itself, but they may also be exported to an external file. Assuming you have employed a solid layer standard like the NCS, you can build a library of layer states to automate tasks such as turning layers on/off, changing the color of layers, and more.

Instead of making the layer visibility changes in step 3 manually, try import- ing and restoring a layer state found in this chapter’s set of download files.

1. Select Manage Layer States from the Layer States drop-down list found on the Home tab ➢ Layers panel.

The Layer States Manager dialog box opens.

2. Click the Import button in the Layer States Manager dialog box, and browse to the file 12-Start.las, found in the Chapter 12 down- load. To see the file, you may need to change the Files Of Type setting to Layer States in the Import Layer State dialog box.

After you click Open to load the 12-Start.las file, the Layer State - Successful Import dialog box opens.

3. Selecting the Restore States button from the Layer State - Successful Import dialog box will automatically apply the imported layer state. You’ll look at the restore options in more detail in a moment, so click the Close Dialog button for now.

4. The lower-right corner of the Layer States Manager dialog box has a circular button with an arrow pointing to the right. Click it to expand the dialog box.

5. When you are restoring layer states, it’s not necessary to restore all properties associated with a layer. Instead, using the expanded Layer States Manager dialog box, you can pick the specific properties to restore by checking or unchecking the associated property.

6. With the 12-Start layer state selected, click the Restore button found at the bottom of the Layer States Manager.

The Layer States Manager closes, the selected layer properties are restored (all properties in this case), and you are taken back to your drawing.

4. Set the Endpoint and Midpoint object snaps to be running.

5. Set the status bar so that only the Object Snap and Dynamic Input buttons are in their on positions.

6. Click the Annotate tab. Your drawing will look like Figure 12.1.

Making a new Dimension Style Each dimension has several components: the dimension line, arrows or tick marks, extension lines, and the dimension text (see Figure 12.2). An extensive set of variables stored with each drawing file controls the appearance and loca- tion of these components. You work with these variables through a series of dia- log boxes designed to make setting up a dimension style as easy and trouble free as possible. Remember that AutoCAD is designed to be used by drafters from many trades and professions, each of which has its own standards for drafting. To satisfy these users’ widely varied needs, AutoCAD dimensioning features have many options and settings for controlling the appearance and placement of dimensions in drawings.

naming a Dimension Style

Every dimension variable has a default setting, and these variables as a group consti- tute the default Standard dimension style. As in defining text styles, the procedure is to copy the Standard dimension style and rename the copy—in effect making a new style that is a copy of the default style. You then make changes to this new style so it has the settings you need to dimension your drawing and save it. Follow these steps:

1. Click the Dimension, Dimension Style button, the small arrow on the bottom-right end of the Dimensions panel on the Annotate tab, to open the Dimension Style Manager dialog box (see Figure 12.3).

On the top left in the Styles list box, you’ll see Standard highlighted, or ISO-25 if your drawing is in metric.

2. With Standard (ISO-25) highlighted in the Styles window, click the New button on the right side of the Dimension Style Manager dialog box.

The Create New Dimension Style dialog box shown in Figure 12.4 opens.

3. In the New Style Name field, Copy of Standard (ISO-25) is highlighted. Enter A-DIMS-PLAN, but don’t press ↵ yet.

Notice that Standard (ISO-25) is in the Start With drop-down list just below. Because it’s the current dimension style in this drawing, the new dimension style you’re about to define will begin as a copy of the Standard style. This is similar to the way in which new text styles are defined (as you saw in Chapter 8), taking an existing style that is close to what you need and modifying specific elements. The Use For drop-down list allows you to choose the kinds of dimensions to which the new style will be applied. In this case, it’s all dimen- sions, so you don’t need to change this setting.
