InsertSheet MetalExtruded Flange

The Extruded Flange command enables you to create a flange starting from an open profile (containing only lines and arcs) with one of its endpoints on an edge of a solid. The flange thickness is automatically inherited and is the same as that of the solid. The bends are automatically created where necessary.

By selecting the appropriate option in the Type drop-down list, you can choose the method for edge selection to create the flange on it.

You can define the length of the flange by using the Extension option available under More Options, either by specifying the distances of the side faces of the flange from the end points of the selected edge, or by specifying one of this distance values and the actual width of the flange.

If you select more than one edge, and the Extension is set to 1st distance and 2nd distance, the At each edge check box is available that is be used to specify the flange length over each edge. On selecting this check box, the 1st Distance and 2nd Distance mini-dialog boxes are displayed for each selected edge. The mini-dialog boxes are active for one edge at a time. To cycle between the mini-dialog boxes either click on it or use the TAB key.

If you select more than one edge, or choose the Chain or Tangency Chain types, you can control the command behavior at the corners formed by the adjacent edges. To extend the flanges so that they cover the corner formed by two edges and meet — at a distance given by the Gap value under Local Properties — at the bisector line, select the Miter check box under More Options. Deselect the Miter check box to prevent flanges from covering the corners.

Finally, when all the selected edges are coplanar, the Keep Orientation check box under More Options enables you to create multiple extruded flanges maintaining the angle between the profile and the plane on which all the edges lie, rather than the one between the first edge and the corresponding outer surface.

To locally change any of the Sheet Metal parameters related to this command (see Sheet Metal category of the Entity Properties), select Local Properties and proceed as described in Local Properties and the Lock Marker.
