The Bottom Line

SolidWorks has a wide range of features beyond the basic extrudes and revolves. You saw the
depth of the standard features in Chapter 7 “Modeling with Primary Features”; now in
Chapter 8, you have seen the breadth of some of the less-used, but still useful operations. You
won’t use each of these secondary features every day, but it is nice to know that if you need to
show a model in a flexed in-use state, you at least don’t have to directly model the deformed part
manually.
The need to custom-design springs in the design of small mechanisms is quite common.
Having the ability to create such designs is a valuable skill.
Master It Use a Helix and a 3D sketch to create a sweep path for a spring with elongated
ends for use in a light mechanism.
Packaging and fixturing are additional types of design and modeling that are important for an
engineer to master. Create a cavity such that the file named Chapter 8 Bottle.sldprt can
nest into it.
Master It Use the Indent feature to create the cavity in a thin sheet of material.
Text often has to go on irregular surfaces. Work through this example to gain some experience
putting it there.
Master It In the downloadable file Chapter 8 Tutorial Bracket Casting.sldprt, some
text is wrapped onto one of the cylindrical bosses. Put a model number on the second boss
using the same process.
