Chapter 27: Working with Surfaces
If you had to go through these steps manually, then you would use the Replace Face feature to
integrate the surface into the solid. The key to integrating the Fill Surface directly into the solid
without any additional features is the Merge Result option in the Fill PropertyManager.Memory surface
A memory surface is not another new type of feature that you can select from the menu or a toolbar;
it is just the name that I gave to a technique that I use from time to time. A memory surface is just
a Knit or Offset Surface that is made at one point in the feature tree when a particular face is
whole, and reused later when the face has been broken up, but you still need to reference the
entire original face. An example of this technique is shown in Figure 27.21. In this case, extra
material is created around the opening, and a surface that was created in a Rollback state is used to
remove it.FIGURE 27.21Using the memory surfaces technique to cut away unwanted geometry
Tutorial: Working with Surfaces
This is another chapter that contains many important ideas, and yet there is only so much space
for tutorials. The best way to learn is to experiment. I recommend that you closely follow the tuto-
rial steps once, and then, when you understand the concepts involved, that you can go back and
experiment.
