If geometry, from an Ideas part needs to be added to an existing FEM, in NX 12.0, the following proceedure is available to add the part to the FEM.
Solution
NX 12.0 still includes the Ideas *.xpk extension type.
The File -> Open and File -> Import function can be used to add the geometry from the Ideas File Exchange Package, *.xpk file.
1. Make the NX Master Part, of the active the FEM. the Displayed Part. Select Application Modeling.2. Select File -> Import -> Part and check the Create Named Group Checkbox. Scale = 1.00(or as needed), Layer = work radio button and the Destination CSYS= WCS. Setting the Destination Coordinate System to Specify, uses a specific CSYS to be used as the Destination orientation. Click OK to continue
3. After the Import Part file selection dialog diaplays, set Files of Type = *.xpk. and select the desired *.xpk file. OK to continue
4. The point dialog then displays. It allows the geometry to be imported into the NX part at the proper location. If the original part is in its "rigged" position/orientation, the reference can be set to Absolute Work Part, 0.0,0.0,0.0 as the reference point. OK to import the geometry. Once OK'd cancel the Point dialog as needed..
5. Make the FEM the Displayed Part. If needed, Edit the FEM and check the Edit Body to Use checkbox. Select the appropriate Bodies to Use dropdown option to add the body or bodies to the FEM.
