3.2 Why can't I select my model for the hardness levels?

You have set the basic hardness for the insert, but you cannot select your model to define the hardness with the right mouse button.

SOLUTION: Check whether the model is embedded in the insert. Only models that are not embedded and can therefore be customised on the insert can be selected in CUBIFY.

If you do not want to redesign the inlay, you will have to select the model grid manually.
