Creating Solids and Surfaces from 2D - Autodesk AutoCAD 2013 Practical 3D Drafting and Design - page 111

• Settings : This option displays a dialog box where we can control the
surface of the created image at cross sections. If the chosen shape is
Smooth Fit , we control the start and end continuity and the bulge mag-
nitudes; if it is Draft Angles , we control the start and end angles and the
magnitudes.
Exercise 4.4
We are going to create a bathtub from scratch, with the necessary cross sections
and guides, by following these steps:
1. Create a rectangle of 2.2 x 1.2 units.
2. Create another rectangle of 1.8 x 0.9 units with a fillet radius of 0.2 in
all corners and center its width with the first rectangle.
3. Copy both objects by 0.6 units in the Z direction.
4. The inner rectangle at the bottom is moved by 0.15 in the Z direction.
5. The rectangle that is selected last is scaled by 0.92 units to a point near
the right-hand edge.
