Blends include options for multiple radii at specified points that can be subsequently modified. Individual faces can be removed for local operations and surfaces can be thickened into solids. Draft is applied to faces at a point referencing the current construction plane. Failed operations give a simple 'could not build message' rather than any debugging assistance. The original Microstation joint system has now been replaced by a fully parametric system based on the integrated motion analysis tools.
Constraints appear in the assembly feature manager.
Once constrained, dragging components dynamically actuates the full mechanism. Sub assemblies can be locked. Cam forms can be simulated using a contact constraint and any volumes of intersection can be saved as separate solids. These can be used for a Boolean subtract operation in order to create part clearance. A bill of materials from an assembly can be inserted directly into a drawing sheet.
