Experiment No. 3POLY OBJECT: COMMAND REC AND DRAWING PLATE

1. Objective(s): IDENTIFY, FORMULATE AND SOLVE complex engineering problems with poly object

commands and applications. APPLY the principles of ethics to commit the professional ethics and responsibilities on creating

ideas and techniques using AutoCAD applications. CREATE a figure using poly objects and rectangle command.

2. Intended Learning Outcomes (ILOs):The students shall be able to:2.1 Create a drawing plate using AutoCAD Poly Object Commands.2.2 Apply the principle of creating a drawing plate using various poly object commands and use the

mathematical geometrical coordinate knowledge on setting one’s own work.2.3 Develop critical thinking on selecting one’s own techniques for the AutoCAD Poly Object

Commands.2.4 Discuss the different application on creating a drawing plate used in AutoCAD.

3. Discussion:

Open a new drawing. Click New

Open new drawing. Make sure you’re in 2D Drafting & Annotation workspace.

Type z [Space bar], type e [Space bar]. This will zoom extents your drawing area.

From the ribbon tools, click CIRCLE

Specify center point of the circle at 5,5. Type 5,5 [Enter]

Specify radius of circle to 4. Type 4 [Enter].

20

Tips: Your center point of circle could be anywhere, instead of input coordinate (5,5) you can point and click anywhere as your center point of circle.

Creating circle in AutoCAD had many ways to do it. If you click CIRCLE tool drop down you can see other ways you can create circle.
