A flanging allows creating a bend in sheet part along a free-form flat edge or a chain of tangentially joined edges.
Creation of a curved edge bend is a deformation operation when the sheet is extended and its thickness decreases. In KOMPAS-3D, this change of thickness is not accounted for when flanges are created in the sheet part.

Example of a sheet part with bends along curvilinear edges
The edge along which the flanging is built is a bend base line, and its sheet solid face (outer or inner) is a bend base face. The base face can belong to either a flat portion of a sheet part or to a bend. Examples of creating flangings are shown in the figures.

The bend surface of the flanging is formed by moving an arc of a given radius along a specified edge, at that the plane of the arc will always be perpendicular to the edge.
The bend of a flanging created along a straight-line edge is cylindrical and does not differ from the bends created using the Bend. That's why the Bend command is more convenient for creating cylindrical bends.

Note the following when working with a sheet part that contains a flanging. Flanging along the curvilinear edge or chain of smoothly joining edges, then edges of such flanging cannot be used in operations Flanging and Cap corners. |
