Relief Assistant

Relief assistant

From thick sheet metal defined without a bend radius or relief and from a basic face, this command allows you to create corner reliefs, edge reliefs and the associated bends in one operation. It allows you to unbend the sheet metal in one operation.

Creation stages / Use:

Click the icon or select Sheet Metal > Relief Assistant... from the drop-down menu.

Select the reference face.
validate by clicking .

The shape must first be converted into sheet metal and for density shapes before conversion, a face must be removed.


Converted Sheet Metal	Result by clicking the back face

Available Options:

Corner Relief:

Allows you to automatically add corner reliefs.

Select Spherical or Rectangular.

	Spherical type corner relief
	Rectangular type corner relief

Enter the corner relief value.
Check or uncheck Extract on Draft to place or not place corner reliefs on the flattening.

Edge Relief:

Allows you to automatically add edge reliefs.

Select Symmetrical or Welded.

		Symmetrical edge relief
		Welded edge relief

Enter the shifting value.

This setting controls the shifting between the two faces of the edge relief.

Enter the extension value.

This parameter controls the release for the relief tool. When the faces are not perpendicular, without extension, the edge may not be fully broken. In this case, the sheet is not unbendable.

Bends:

By checking this option, you can automatically add bends. 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.
