Chapter 27: Working with Surfaces

Using Fill Surface blend
Sometimes fillets do not meet your needs. Blends, such as those shown in the bike frame example,
are smoother and can blend just about anything. However, the technique is not exactly straightfor-
ward. Follow these steps to gain familiarity with this technique:
- Open the part from the CD-ROM for Chapter 27 called Chapter 27 – Blend.
SLDPRT. Box select all the features from the DeleteFace1 to the Shell, and suppress
them.
- On the Top plane, draw a square 2 inches on a side and centered on the Origin.
- Use the Split Entities tool found on the Sketch toolbar or choose Tools ➪ Sketch
Tools ➪ Split Entities from the menus. Divide each line of the rectangle into three
pieces, with the two outer pieces of each line being .6 inches (use an Equal sketch rela-
tion). The sketch should be fully defined when you are done. This arrangement is
shown in Figure 27.26. This is done because the edges of the tubes need to be broken
into sections.
- Use Delete Face to delete the ends of the four tubes. Set the option to Delete, not the
default option of Delete and Patch. This converts the solid into a surface body.
- Use the sketch with the split entities to trim out the center section of the tubes,
keeping the outer section and leaving four surface bodies. This divides each tube end
into four segments where they have been trimmed, as shown in Figure 27.27.
