The PC-DMIS help file defines TP of a group as follows:
1. Create a feature set of the holes from the Set menu option (see "Constructing a Set of Features" from the "Constructing New Features from Existing Features" section for instructions on creating feature sets.).
2. Select the True Position menu option. The True Position dialog box appears.
3. From the True Position dialog box, select the created feature set as the input feature, and select any other options used for the dimension.
4. Select the Textual check box from the Analysis area.
5. Access the Edit Window toolbar, and select the Report Mode icon. You are now able to see the deviation of each feature and the translation and rotation required to bring the features into tolerance. Results are always shown using Regardless of Feature Size (RFS) on Datum to see the maximum deviation.
My question is this, is this right?? I always had trouble believing the "Set" was actually the center of the group. I have two holes with the TP callout back to a center hole datum and I have to TP them as a group. Just wondering if this is the best way or should it be one hole to the other?
Thanks in advance.
