If the current geometry representation for the geometry sequence is CAD kernel, an automatic conversion of COMSOL objects to CAD objects takes place before using the objects in Boolean operations and before using the objects in the
Convert to Solid,
Convert to Surface,
Convert to Curve, and
Convert to Point operations. This ensures that the CAD kernel is used in the abovementioned operations. This conversion is also performed when COMSOL objects are used as input to features that require the CAD kernel, for example the
Knit to Solid feature
