Updating Modified Geometry
Updating geometry:
– After modifying the source geometry the project schematic will show a refresh/update state for the model (RMB to complete).
– When “Yes” (default), dimension names containing the parameter key (default is “DS”) will be imported into Mechanical. – To import all parameters leave the parameter key field blank. – CAD parameters will appear in the Details view for the Geometry.

Please note, not all import capabilities described here are available with all CAD systems. Features depend on CAD capabilities and the support provided through the CAD vendor’s API.
– IGES Geometry Interface reader is provided for all installations.
DesignModeler is the Workbench geometry application and supports all the functions and capabilities listed for commercial CAD systems.
– Not all CAD software have the same features, so there are some differences in CAD-related functionality which is supported in Mechanical.

– Assemblies with mixed solids and surfaces are OK. – Select desired geometry type to filter import. – Cannot import a part with mixed solids and surfaces.
Material Properties: allow material property import from supported CAD systems (see the current documentation for properties supported by various CAD vendors. Materials imported from CAD will appear in the “Engineering Data” branch and will be assigned to individual parts.
– Geometry, Spot welds, Parameters, Material properties, etc.

If “groups” are defined in the CAD package they can be imported as Named Selections:
– “Groups” containing the specified prefix in their name are imported in the Named Selection branch (default is “NS”). – To import all groups leave the named selection key field blank.
– If the material type is changed in CAD, this will be reflected in an update. – if the property values of the material change in CAD, this will not update.
