Import PMI from a JT file

You can import PMI from a Teamcenter lifecycle visualization JT file. PMI can include linear, angular, and radial dimensions, upper and lower specification limits, nominal values, dimensional text notes, upper and lower surface finish roughness values and ISO details, and both regular and composite GD&T feature control frames (FCFs) derived from JT. Set the Mci0ExtractPMISurfaceProperties preference to true to retrieve surface properties such as position X, Y, and Z, and direction I, J, and K.

You can import all data from a product structure or specific data from the part table or 3D window of the Graphics view.

Procedure

1. If you have not already done so:

   Install JT Open Toolkit that is supplied with Teamcenter externally from Teamcenter. Note The JT Open Toolkit supplied with Teamcenter is stamped with a Manufacturing license, and any other toolkit package will fail to work.

   In NX 7.5 or greater, define the PMI information—for example, features, datums, tolerances, and FCFs—to be imported. Use the JTTK Inspector to verify which properties can be extracted.

   In NX, use JT Open Toolkit to export the JT file as documented in the NX help.

   In Teamcenter, create a product structure and apply the JT file to a Direct Model dataset.

2. In Multi-BOM ManagementPart Planner, from the product structure, select a BOM line containing child lines as well as the directModel dataset.

3. From the product structure, right-click a BOM line containing child lines as well as the directModel dataset to which you want to import PMI information and choose Open with→PMI Manager.

4. Click to open the Graphics view.

5. From the product structure, show the JT image, right-click the image, and in the Graphics view, choose Show PMI.

6. Do one of the following.

   To import all PMI data, in the Graphics view, right-click the part and choose PMIs→Import PMI from JT. Tip You can also import PMI from the PMI Manager toolbar. To import specific PMI data, in the list or 3D viewer of the Graphics view, press Ctrl and select each PMI element you want to import.
   In the product structure, right-click the part and choose PMIs→Import selected PMI from JT.

Results

Because the JT toolkit provides different ways to store information on JT files (assembly, part, monolithic), PMI objects are imported under the part the JT was created with, without any validation that those objects are attached to the part in the Graphics view. You can move, update, and delete PMI objects as necessary after import. The information is read from the JT and no changes are applied to the JT file. You can now assign the PMI objects to operations.

Note

If the JT is updated and you reimport PMI, new PMI objects are added, existing PMI objects are updated, and missing PMI objects are deleted.
