By checking this option, you can add bends to each vertex of your section. These bends can be defined by different ways:

The indicated radius corresponds to the inner bending radius.

 

Manual: The radius has to be entered.

 

Thickness: The radius is synchronised with the thickness of the sheet metal.

 

Unfolding rules: The radius of bend to use is search in the table defined in the unfolding rules associated to the part. According to the thickness of the sheet metal to consider, TopSolid uses the first favorite bending radius found in the list of available radii.

 

 

 

The Delimit bends option allows to isolate faces of the bend from those of connected faces for example to be able to use the covering.

 

Without Delimit bends option

With Delimit bends option

This option can be activated by editing the command or by using the Delimiting of Bend command.
