Reference Point
Any visible model point can be constrained to be a reference point. Solve places reference points in the variation at the position specified by the constraint.
To assign a reference point:
1. In the Generate Constraints dialog box, click the Assign radio button. Then pull down the Type selection list and select Refpoint.
2. Click Apply.
3. Click the point to be constrained. You may select any visible model point (Use the Creo Elements/Direct Drafting Show dialog box to display model points if needed) If a point element does not exist at the location you click, one will be created.
4. Input a position for the reference point. You have two options:
◦ Click End or select another point. The reference point will be placed into the variation at its current position at solve time.
◦ Enter a parameter name or Creo Elements/Direct Drafting expression that resolves to the point position (string input).
The reference point will be labeled with the position symbol. See
Constraint Icons. If the reference point is set to a parameter name, that information is appended to its icon.
