Chapter 29: Using SolidWorks Sheet Metal Tools

Faces to Match

The faces selected in the Faces to Match selection box act as an “up to” end condition for the faces

to extend. Prior to SolidWorks 2010, the Closed Corner feature always automatically selected a

matching face to extend for each face selected, when appropriate. SolidWorks 2010 enables you to

manually select matching faces in the Faces to Match selection box for those times when the auto-

matic selection does not work.

Note
If you deselect faces in either the Faces to Extend or Faces to Match selection boxes, the Auto Propagation
option toggles off to enable you to make selections manually. n

Gap

The Gap setting enables you to specify how close you want the closed corner to be. Keep in mind

that you cannot use the number zero in this field. If you do, then SolidWorks reminds you to

“Please enter a number greater than or equal to 0.00003937 and less than or equal to

0.86388126.” It is good to know your limits.

Overlap/Underlap ratio

The Overlap/Underlap ratio setting controls how far across the overlapped face the overlapping

flange reaches. Full overlap is a ratio of 1, and a Butt condition is (roughly) a ratio of zero. This

ratio is only available when you have specified Overlap or Underlap for the corner type.

Open bend region

The Open bend region option affects how the finished corner looks in the bend area. If Open bend

region is selected, then a small gap is created at the end of the bend. If the option is deslected, then

SolidWorks fills this area with geometry. Figure 29.22 shows the finished model with this option

selected and unselected, as well as the resulting Flat Patterns for each setting.
