Lesson: Creating Basic Objects
All drawings consist of basic objects that you create using basic commands. In this lesson, you learn
how to create objects such as lines, circles, arcs, rectangles, and polygons. You also learn how to use
the Erase command to erase objects.
Learning to create basic geometry is critical to success in the software. As you become proficient with
basic geometry creation, you can move on to creating more advanced object types.
Objectives
After completing this lesson, you will be able to:
■ Use the Line command to create lines in the drawing.
■ Use the Circle command to create circles in the drawing.
■ Use the Arc command to create arcs in the drawing.
■ Use the Erase command to erase objects in the drawing.
■ Use the Undo and Redo commands to return to previous drawing states.
■ Use the Rectangle command to create rectangles in the drawing.
■ Use the Polygon command to create equal-sided polygons in the drawing.
