If the model had been exported as a solid from the originating system, the Creo application automatically transforms it from quilts to a solid when you import it. When you import STEP geometry and some solid geometry already exists, you can create a solid cut or solid protrusion or you can import them as quilts.

When you import a STEP file that contains only surfaces, the system creates quilts out of the surface data upon import. If the STEP file contains surfaces (as opposed to a solid) with all necessary topology for surface connection, you can create a solid while redefining the imported feature. If imported files do not have information on surface connection, you can join surfaces in several ways.

You can use profiles for the import. Import log files are automatically generated in the working directory when the import is complete.

The import also includes non-geometric data such as material name and density, the assembly validation property to verify the number of child components of an assembly node, user-defined parameters, STEP groups, graphical and semantic annotations, and the combined states. The ap203_e2 and the ap214_is formats support the exchange of annotations that include Product Manufacturing Information (PMI). The AP242 format supports the import of PMI graphical representations. STEP groups are imported as layers.
