Geometric’s FR technology automatically extracts a wide range of features from 3D solid models. FR consists of three different libraries; namely, Design View FR, Manufacturing View FR and Sheet Metal FR. FR provides feature tree information and respective feature parameters, parent-child relationship in case of intersecting features and alternate interpretations of features.
Unfolding imported sheet metal models in CAD modelers always has limitations. Imported models having flanges as that shown in the figure below are not possible to unfold in most of the CAD modelers.
The latest version of Sheet Metal FR now has the capability to unfold imported models with such flanges. By enabling the patch stamps option, the above imported model can be unfolded with ease as shown below.
