Want to add control points to a surface (which is the only one displayed on screen) but don't know which bonded surfaces might be affected? Please add a "Show Bonded surfaces" option together with the "show Intersecting Sufaces" and "Show Only Selected" when right-clicking in the Assembly Tree.
This is now in Modeler 2026
The Bonding data is shown in the last column of the Surfaces table.
But your suggestion of displaying the Surfaces bonded to the selected one shouldnt be too hard to implement so will try to get that done for the next release
