Select the File | Import | STEP menu option to show an Import dialog box.
Select the data type you want to import from the file-type list.
Use the Import dialog box, and navigate to the folder that contains the file to import. Then select the file.
Click the Import button. PC-DMIS imports the STEP file. A progress bar appears and indicates the progress
If your model contains embedded GD&T callouts, PC-DMIS asks if you want to create Edit window commands from the GD&T callouts:
If you click Yes, the importer also imports and converts the GD&T callouts into GD&T and other Edit window commands.
If you click No, the importer does not convert the GD&T callouts. (You can always use the Operation | Graphic Display Window | Select GD&T menu item to convert all the CAD GD&T callouts later; or for specific callouts, you can box-select or click on them. For additional information on CAD GD&T callouts, see "Working with CAD GD&T Callouts".)
During the import process, you can cancel or stop the import.
Cancel - This button cancels the import altogether. If you already had a CAD model loaded before the import, PC-DMIS retains the previous CAD model.
Stop - This button stops the import, but keeps any imported CAD elements up to that point.
