Chapter 27: Working with Surfaces
FIGURE 27.12The MidSurface PropertyManager
If you were to manually perform the functions that are done by Replace Face, then you would start
by deleting several faces of the solid, then extending faces, and then trimming surface bodies, and
finish by knitting all the trimmed and extended faces back into a single solid body.This is a very powerful and useful tool, although it is sometimes difficult to tell which situations it
will work in. Figure 27.13 shows a part before and after a Replace Face feature has been added.
The surface used to replace the flat face of the solid has been turned transparent. The first selection
box is for the original face or faces, and the second selection box is for the surface body with the
new faces. The tool tips for each of the boxes are Target Faces For Replacement and Replacement
Surface(s), which seem a little ambiguous. I like to think of them as Old (top) and New (bottom).Untrim Surface
The Untrim Surface is discussed in the terminology section of this chapter. You can use it either
selectively on edges or on the entire surface body.
Parting Surface
The Parting Surface is part of the SolidWorks Mold Tools. The Mold Tools are addressed in
Chapter 32.
