Create/New/Show Allowance Method
The HiCAD Sheet Metal functions:
enable you to choose between different allowance methods in sheet development.
The bend areas for sheet constructions are modelled as approximated cylinder segments. During development, the individual segments are transformed to a plane and assigned additional stretching. This is to allow material elongation to be taken into account in partially plastic bending. HiCAD also provides the empirical allowance methods standard in practice.
