Converts the CAD design to a parametric design, opening a new parametric child view onto it. The
parametric designs lose the CAD menu command capabilities and becomes defined and modifiable entirely
by typing dimension values. The parametric design can be converted back to a CAD design at any time.
If the parametric design is to be saved as a template file, having created it from a CAD design by
conversion, then it is usual to delete out the parameters that are not wanted using the right click Delete
command on the property editor menu pop-up menu (right click to access).
