Our 3D CAD supplier models have been moved to 3Dfindit.com, the new visual search engine for 3D CAD, CAE & BIM models.
You can log in there with your existing account of this site.
The content remains free of charge.
The docking window 3D History is a central „arena“ within PARTdesigner. Via its context menus, the Sketcher (with Sketch history) is called and the part created.
Furthermore in the history all design steps are documented, so that you can retrace later how a part is assembled and possibly modify a step.
