Creating Solids and Surfaces from 2D - Autodesk AutoCAD 2013 Practical 3D Drafting and Design - page 118

Exercise 4.5
With the SWEEP command, we are going to create an ogee on the line that repres-
ents a ceiling by following these steps:
1. Create the following 2D polylines (the one on left-hand side will be the
path and the one on right-hand side will be the section):
2. With the LAYER command, a layer for the sweep object is created and
activated.
3. Now apply the SWEEP command. The polyline on the right-hand side is
the section. Before the path, choose the Base point option and specify
the upper-left corner of the section as the point that will follow the path.
Finally, select the polyline on left-hand side as the path.
4. Save the model with the name A3D_04_05FINAL.DWG .
