Link between Relation3d and Dimension


Hi at all,


I'm new here. I hope, I have a simple question, but I can find a solution. I have add a relation PlanarRelation3d (AddPlanar) and all works fine. Now I wants to set a formula in the dimension (variable) of the relation. I intend to use the variable table, but I can find the system generate name of the dimension.


Thank you in Advance!
