Sheet metal corner options reference

Defines the parameters for all aspects of a corner in a sheet metal feature.

Overrides default parameters in the Sheet Metal Styles dialog box that define how corners are relieved when a folded model is unfolded. Change these parameters for individual features using the Corner Options tab.

Access
In the Contour Flange, Flange, or Corner Seam dialog box, click the Corner tab.
Note: Not all options described are available or valid for each feature that shares this tab.
Defines the Default corner relief shape when 2 bends intersect
Round
A circular cut out centered on the intersection of the bend lines.
Square
A square cut out centered on the intersection of the bend lines.
Tear
Extends the flange edges to their intersection. No relief, which allows material failure (tearing) across the bend zone in the folded model.
Trim to Bend
A polygonal cut out bounded by the bending zone lines.
Linear Weld
A V-shaped cut out defined from the intersection of the inner bend zone lines to the outer bend zone intersection of the line with the flange edges. Minimum relief allows a subsequent weld operation to close the corner.
Arc Weld
Curves tangent to the flange edges along the outside edge of the bend zone which converge to a flat gap equal to the Miter Gap value. A gap between the flanges that is equidistant along the length of the relief is suitable for subsequent arc welding.
Defines the Default corner relief to display in the flat pattern when three bends intersect
Note: The folded model does not display the selected relief option.
No Replacement
Does not replace the geometry as modeled in the flat pattern
Intersection
Extends and intersects the flange edges.
Full Round
Extends the flange edges to their intersection, and then places a fillet tangent to the bend zone tangency lines. Radius are likely larger than what is produced using the Round with Radius option.
Round with Radius
Extends the flange edges to their intersection, and then places a tangent fillet of the size specified. Radius is likely smaller than what is produced by the Full Round option
Relief Size
Controls the size of the Corner Relief of the selected feature from the default, as defined in the Sheet Metal Style, using the named parameter: CornerReliefSize.
Apply Auto-Mitering
Automatically extends material between adjacent flange edges during creation or edit of at least two flange edges during a single operation where bend angle is greater than 90 degrees. Available on Flange and Contour Flange dialog box (not available on Corner tab of Corner Seam dialog box).
  • Apply Auto-Mitering turned on.
  • Apply Auto-Mitering turned off.
Miter Gap
When the Auto-Miter is turned on, you can enter a value to change the size of an automatically applied gap between flanges. The value displayed defaults to the system named parameter GapSize, which is defined in the Sheet Metal Style.
2 Bend/3 Bend Corner
Indicates the type of corner relief to apply to the selected geometry. Available only when a choice must be made between the type of corner being specified. When inactive, they indicate the type of corner selected.
