PartDesign Migrate

Description
The PartDesign workbench in FreeCAD v0.17 introduces new tools and elements that are not recognized by older FreeCAD versions (0.16 and older). FreeCAD documents created in older versions can still be opened and edited. To benefit from the new features, they must be migrated via the menu PartDesign → Migrate.

Usage

 * 1) Open a FreeCAD document that was created with FreeCAD
 * 2) Switch to the  workbench.
 * 3) Go to the Part Design → Migrate menu.
 * 4) If the migration works, a Std_Part.svg Part container will be created which will hold one or more PartDesign Body.png Bodies, each hosting a chain of features.

Limitations

 * Before starting the migration process, check if the model was built with automatic refine options enabled (in ), and set your preferences accordingly. This can be easily determined by successively toggling the visibility of the features in the Model tree. If no residual edges are left between features such as Pads and Pockets, the automatic refine options were disabled.
 * If a document to migrate only contains sketches and PartDesign features, the migration process may likely succeed. Some features such as chamfers and fillets may require rebuilding.
 * If the document to migrate has a mixed Part/Part Design/Draft workflow, the conversion will most likely fail or at best produce unexpected results, and will need to be migrated manually.
