626 | Chapter 21 Surfacing Wireframe Models
Creating Trimmed Planar Surfaces
Begin by surfacing the top section of the pump model, creating the individ-
ual surfaces. Top A is a planar surface because it is flat with sharp edges. Tops
B and C are swept surfaces, bounded by curved wires. Top B uses two curves
and two rails, and top C uses one curve and one rail. You trim the top C sur-
face where it extends beyond the wireframe boundary.
As you gain experience using the menu selections that correspond to com-
mands, you may want to use shortcuts. For a list of shortcuts that automate
the selection of menu options and commands, see Accelerator Keys in the
online Command Reference.
NOTE For a trimmed planar surface, the surface must be a single polyline that
lies in a single plane. If the wireframe is composed of multiple polylines, join
them into a single polyline before you create the surface.
