Siemens NX Center Constraint

Nahid Mubin · Apr 11, 2025

In siemens NX's center constraint, I can set two faces of a body two be in the center of two faces of another body. But these constraints only work if the faces are all parallel. You can check my previous thread here to understand the issue- https://www.eng-tips.com/threads/center-constraint.513106/

Now I want that this constraint should also work incase the faces are symmetric even if not parallel. How can I add this option using NXOpen python API?

Create a datumplane in the center of each pair ( The bisector plane) use the datum planes instead for the constraint. ( Touch/Align since it's 1 on 1)
If you anyway are to write code for this, you would be using ootb functionality and full associativity.

If your case is similar to the one shown in the other thread, you can use the linear edges instead of the faces. Or create geometry in the file just for the constraint. All the suggestions in that thread are valid and useful.
