Chapter 29: Using SolidWorks Sheet Metal Tools
FIGURE 29.35Using the Rip feature
Note
Rip functionality is included in the Insert Bends Sheet Metal PropertyManager when it is first initiated, although it
is no longer there when you edit the part later. If you use it, the Rip data becomes a feature of its own and is
placed before the Sheet Metal feature in the FeatureManager. Be aware that there are slight differences between
using the Rip function as an independent feature and using it as a part of the Insert Bends feature. You may want
to check this on a part you are working with to verify which method best suits your needs. n
Sheet Metal feature
The Sheet Metal feature used in the Insert Bends method is very similar to the one used in the Base
Flange method. However, two main differences exist: Insert Bends Sheet Metal requires the user to
select a Fixed Face, and Base Flange Sheet Metal allows the use of Gauge Tables. Both features
function as placeholders and otherwise contain the same information, use the same name and icon,
and are inserted automatically when a different feature is created.
Flatten Bends feature
The Flatten Bends feature is added automatically by the Insert Bends tool. As mentioned earlier, it
takes the model with sharp corners and lays it flat, adjusting the material in the bend area and nor-
malizing the thickness faces around the Flat Pattern. The Merge Faces option is available in the Flat
Pattern feature in the Insert Bends method ; therefore, the Flat Pattern created by the Flatten Bends
feature always has edges created by the tangent lines of the bends.
Notice in Figure 29.36 that the Flatten Bends feature has a sketch and several Sharp Bend features
under it. The Sharp Sketch is simply an account of the bend lines, and you cannot edit it manually.
The Sharp Bend features can be suppressed, in which case they are not re-formed in the Process
Bends feature. You can also edit Sharp Bend features to change the default radius, bend allowance,
and relief type.
