HiCAD
HiCAD is a 2D-/3D- CAD-system from ISD Software und Systeme GmbH based on the software kernel ESM (European Solid Modeller), developed by ISD.
HiCAD supports 2D design and 3D modeling. The construction method can also be freely selected between the parametric and feature-and the free and direct construction. In parametric design the construction work starts with the mental model construction, with all parameters and conditions. However, In free design changes can be made directly in the 3D model, without considering the history of a part.
