INSTITUTE OF ENGINEERING AND TECHNOLOGY AERONAUTICAL ENGINEERING DEPARTMENT LABORATORY MODULE NO. 2 : LINES AND DYNAMIC INPUTS Course Learning Outcomes [CLO] CLO 1. Manipulate and understand command functions by creating and recreating accurate figures. CLO 2. Produce accurate dimensions and scales of different figures and structures by the drafting program both in 2- dimensional and 3-dimensional planes.. CLO 4. Accomplish tasks via drafting software with accuracy and precision and develop a sense of automation when executing commands with the use of keyboard ie; automatically pressing the letter โ€œLโ€ instead of selecting program ribbons and toolbars. CLO 5. Handle criticism regarding designs and products that were individually done through improving initially submitted outputs CLO 6. Build logically on the foundation until the students has a reasonable competency in most of the functions of the CADD. CLO 7. Instill the engineering approach on designs that are realistic in nature. CLO 8. Fulfill certain tasks under a specified amount of time limit yet produces accurate drafts. CLO 9. Incur self-confidence and independence by individually working on accomplishing any given task. Module Learning Outcomes [MLO] MLO 1. Recreate figures exercising critical thinking and analysis MLO 2. Create 2D figures exercising creativity and imagination. Topic Learning Outcomes [TLO] TLO 3. Application of line command by recreating the given figure TLO 4 Demonstrate Familiarization on different CAD coordinate system by applying the correct data input when creating a figure. TLO 5. Recreate figures given figures using linear, curves, special objects, and object snap commands TLO 6. Demonstrate Creativity by creating a figure using dynamic input commands only. LEARNING OUTCOMES HONESTY CLAUSE As individuals of academic community. Students are expected to understand and uphold requirements of intellectual and educational integrity. The college assumes as a simple and minimal preferred of habits in academic matters that students be truthful and that they publish for deposit solely the merchandise of their efforts.

INSTITUTE OF ENGINEERING AND TECHNOLOGY AERONAUTICAL ENGINEERING DEPARTMENT LABORATORY MODULE NO. 2 : LINES AND DYNAMIC INPUTS Line Command Creates single straight-line segments

  1. Choose Draw, Line. or
  2. Click the Line icon. or
  3. Type LINE from the command prompt Command: LINE or L
  4. Press ENTER
  5. Pick From point: ( point )
  6. Pick Specify next point o [Close/Undo] :( point )
  7. Pick Specify next point or [Close/Undo] :( point )
  8. Press ENTER to end line sequence or
  9. Type U to undo the last segment to point: U (undo) or
  10. Type C to create a closed polygon to point: C (close) Cartesian Coordinate System AutoCAD provides the user with an infinite two-dimensional area to work with. Any entities place on the working two-dimensional plane can be defined relative to the Cartesian coordinate system. The Cartesian coordinate system divides a two-dimensional plane with two perpendicular axes. The X axis runs horizontal across the bottom of the screen. The Y axis runs vertically along the left side of the screen. These two axes intersect at the bottom left corner of the screen.

INSTITUTE OF ENGINEERING AND TECHNOLOGY AERONAUTICAL ENGINEERING DEPARTMENT LABORATORY MODULE NO. 2 : LINES AND DYNAMIC INPUTS Polar Coordinates

  1. Type @distance<angle when AutoCAD asks for a point. From point: pick point To point:@1< To point:@1< To point:@1< To point:@1< Dynamic Input Dynamic Input provides a command interface near the cursor to help you keep your focus in the drafting area. When Dynamic Input is on, tooltips display information near the cursor that is dynamically updated as the cursor moves. When a command is active, the tooltips provide a place for user entry. Turning Dynamic Input ON/OFF 1. Click Dyn on the status bar or 2. Press F Tip: Right-click Dyn and click Settings to control what is displayed by each component when Dynamic Input is on.

INSTITUTE OF ENGINEERING AND TECHNOLOGY AERONAUTICAL ENGINEERING DEPARTMENT LABORATORY MODULE NO. 2 : LINES AND DYNAMIC INPUTS Orthogonal Lines Controls lines from being drawn at various angles to straight lines. When the snap grid is rotated, ortho mode rotates accordingly.

  1. Press Function Key F.
  2. Double Click or ORTHO from the Status Bar.
  3. Press or CTRL + L.
