Basic Concepts of Surfacing Wireframe Models | 619
A surface like this one is a basic surface that carries a shape across larger areas.
This surface is referred to as a base surface. Even after many areas of the sur-
face are trimmed away, the underlying base surface remains intact and may
be displayed at any time with the Surface Display dialog box.
Identifying base surfaces is an important part of wireframe surfacing.
Another approach is to categorize surfaces by type and eliminate those you
wont need.
To get shapes you can use for creating surfaces, you may need to break poly-
lines into segments. Then combine selected segments to form boundaries for
individual surfaces.
Using Trimmed Planar Surfaces
Use a trimmed planar surface for an area that you know is a flat plane. By
glancing at the pump model, you can see areas that appear to be flat and can
be surfaced with trimmed flat planes.
