Creo Elements/Direct Modeling allows you to import selected parts (*.prt) or assemblies (*.asm) from Creo Parametric. You can also import parts and assemblies from Granite in the GRANITE native (*.g) format.
Creo Parametric parts and assemblies may contain family tables. Family tables are collections of parts, or assemblies, or features that are essentially similar, but deviate slightly in one or two aspects, such as size or detail features. A family table comprises a base or generic model and its instances. Family table information is stored in generic and instance accelerator files. The generic file contains the generic version of the part or assembly while the instance accelerator file contains a specific instance of the part or assembly. An instance accelerator file carries the .xpr extension for a part instance and the .xas extension for an assembly instance.
If one or more instance accelerator file is missing during import, the corresponding generic instance is loaded. You may use the Save a Backup command in Creo to create the required accelerator files.
To import Creo Parametric or Granite native formats,
1. Click File > Open in the main menu. The Load dialog box opens.
2. In File Type, select Creo Parametric/Direct (*.prt*;*.asm*;*.g*;*.g.zip;*.xpr;*.xas*).
You can now directly open any *.g.zip file in Creo Elements/Direct Modeling. Creo Elements/Direct Modeling automatically opens the top-level assembly.
3. Click Options and choose Quilts, Wireframe, Invisible Parts, Annotation 3D, Blend Recognition, or Statistics in the Read Creo Parametric/Direct dialog box.
◦ Click Quilts to import Creo Parametric quilts. Quilts are used to represent models that are not Creo Parametric solids; for example, face parts or collections of faces. All imported quilts for each part or assembly are grouped in a Quilts container (under that part or assembly) in Creo Elements/Direct Modeling.
◦ Click Wireframe to import Creo Parametric datum curves. Datum curves are single curve parts (wire curves). All imported datum curves for each part or assembly are grouped in a Wire container (under that part or assembly) in Creo Elements/Direct Modeling.
When you import a quilt or a wireframe, the assembly level Quilt and Wireframe geometry is imported and grouped respectively under a Quilt or a Wireframe container. The name of the container is same as the parent assembly.
◦ Click Invisible Parts to import parts that are in the blanked layer. Layers are items stored in Granite part file as a collection of other items.
◦ Click Annotation 3D to import Creo Parametric 3D Annotations.
◦ By default, Blend Recognition is selected. Creo Elements/Direct Modeling automatically detects and recognizes blends so that they can be modified.
◦ Click Merge spline surfaces to merge multiple spline surfaces into one surface.
If you clear Merge spline surfaces, Creo Elements/Direct Modeling independently imports all spline surfaces without merging them.
◦ Click Ignore Missing Models to import Creo Parametric assemblies (*.asm files) in which parts or components are deleted or missing. Creo Elements/Direct Modeling displays a warning for the missing parts.
By default, Creo Elements/Direct Modeling does not import Creo Parametricassemblies in which parts or components are deleted or missing.
◦ Click Statistics to open a log file which contains statistics about the imported information.
4. Select the path where the file should be located.
5. Select a file or type the name of the file in Filename.
6. Click Load.
Example: A model imported from Creo Parametric
The following example shows an assembly with two solid parts (A and B) imported from Creo Parametric. Part A has eight connected components in Creo Parametric. Part A is imported as an assembly named A.PRT with eight parts, named A. PRT.1, A. PRT.2, A. PRT.3, and so on in Creo Elements/Direct Modeling. The single B. PRT part in Creo Parametric is imported as B.PRT.
Limitations
You can import parts (*.prt) or assemblies (*.asm) that are created in Pro/ENGINEER Wildfire 2.0 and later versions up to Creo Parametric 5.0. You cannot import parts or assemblies created in versions before Pro/ENGINEER Wildfire 2.0. To import parts or assemblies created in an older version, recreate the parts or assemblies in the latest version of Creo Parametric and then import the recreated parts or assemblies.
