SolidWorks 2010 Bible

Chapter 29: Using SolidWorks Sheet Metal Tools

Like the forming tools, you can also use Lofted Bends in situations for which they were probably

not intended. Figure 29.31 shows how lofting between 3D curves can also create shapes that can

be flattened in SolidWorks. In this case, a couple of intermediate steps were required to get to the

3D curves, which involve surface features.

This part is included on the CD-ROM with the name Chapter 29 – wrap.sldprt.

FIGURE 29.31

Using 3D curves with Lofted Bends to create flatten complex shapes

Unfold and Fold features

Unfold is a feature that unfolds selected bends temporarily. It is typically used in conjunction with

a Fold feature to re-fold the bends. This combination is used to apply a feature that must be

applied to the Flat Pattern; for example, a hole that spans across a bend.

Figure 29.32 shows the FeatureManager of a part where this combination has been applied, as well

as the part itself, showing the bend across a hole, and the PropertyManager, which is the same for

both features.

Both the Unfold and Fold features make it easy to select the bends without zooming in, even for

small bends. A filter is placed on the cursor when the command is active, which allows only bends

to be selected. The Collect All Bends option also becomes available. This feature also requires that

you select a stationary face to hold still while the rest of the model moves during the unfolding and

folding process.
