More Info - Please find following the section from the Pro/Desktop Help file on importing from Pro/E.
Hope this helps.
Transferring Data from Pro/ENGINEER
Pro/ENGINEER files can be transferred directly into Pro/DESKTOP by either opening or importing the Pro/ENGINEER files in Pro/DESKTOP. There are three options for transferring Pro/ENGINEER files into Pro/DESKTOP:
Open the Pro/ENGINEER *.prt, *.pdt, *.g, or *.asm file in Pro/DESKTOP.
Import the Pro/ENGINEER file into Pro/DESKTOP from the Pro/DESKTOP File menu.
Import the Pro/ENGINEER file into Pro/DESKTOP from a Pro/INTRALINK workspace.
When the Pro/ENGINEER part is brought into Pro/DESKTOP, it is represented as one solid feature. The existing edges and faces of the solid are separately recognized by Pro/DESKTOP, but detail features such as holes or chamfers are not treated as separate features.
When you add features to your Pro/ENGINEER file in Pro/DESKTOP, the new features are treated as normal Pro/DESKTOP features. The three Pro/DESKTOP default workplanes (base, frontal and lateral) are also created.
Accepting Pro/ENGINEER File Changes in Pro/DESKTOP
After using Pro/ENGINEER to make changes to the part file, save the changes. The next time you open that part file in Pro/DESKTOP, the file changes are recognized and Pro/DESKTOP issues a message, warning you that the original Pro/ENGINEER part file has changed. To integrate the changes, click Yes and then update the design in Pro/DESKTOP.
Note:
If you are using Pro/ENGINEER and Pro/DESKTOP simultaneously, you do not have to close and reopen the Pro/ENGINEER part file in Pro/DESKTOP. The warning message will appear after you move from Pro/ENGINEER to Pro/DESKTOP.
After the Pro/DESKTOP file is updated, it may happen that a previously-existing Pro/DESKTOP feature cannot be regenerated. A common cause is deletion of a Pro/ENGINEER object referenced by the Pro/DESKTOP feature.
To open *.prt, *.pdt, and *.g Pro/ENGINEER files in Pro/DESKTOP:
Pro/ENGINEER *.prt, *.pdt, and *.g parts can be opened in Pro/DESKTOP using three different methods:
Drag and drop the file from Windows Explorer into the Pro/DESKTOP application window.
Drag and Drop the file from File Explorer into the Pro/DESKTOP application window.
The File > Open command:
Click File > Open. The Open dialog box opens.
Select Pro/ENGINEER (*.prt, *.asm, *.pdt, *.g) from the Files of Type list.
Browse to the desired file.
Click Open. The Pro/ENGINEER file opens.
To open *.asm Pro/ENGINEER files in Pro/DESKTOP:
Pro/ENGINEER *.asm files can be opened in Pro/DESKTOP using two different methods:
Drag and Drop the file from File Explorer into the Pro/DESKTOP application window.
The File > Open command:
Click File > Open. The Open dialog box opens.
Select Pro/ENGINEER (*.prt, *.asm, *.pdt, *.g) from the Files of Type list.
Browse to the desired file. Note: All assembly component files must be stored in the same location as the assembly file.
Click Open. The Pro/ENGINEER assembly opens.
To import *.prt, *.pdt, and *.g Pro/ENGINEER files into Pro/DESKTOP:
Pro/ENGINEER *.prt, *.pdt, and *.g parts can be imported into Pro/DESKTOP using two different methods. Each method imports the part with the Pro/ENGINEER blue background:
Drag and drop a file from Windows Explorer into the Pro/DESKTOP application window.
The File > Import command:
Create a new Pro/DESKTOP design file.
Click File> Import> Pro/ENGINEER Part File. The Import Pro/ENGINEER dialog box opens.
Enter a name for the imported feature in the Feature Name text box.
Browse to the desired file.
If you want to import individual solids in the Pro/ENGINEER part as components in your Pro/DESKTOP file, click Make Components.
Click Open. The Pro/ENGINEER part imports and opens.
To import *.asm Pro/ENGINEER files into Pro/DESKTOP:
You can import an assembly as a single feature using the Pro/ENGINEER Shrinkwrap option. You must set the Shrinkwrap to the Solid option.
