+/**
+Currently, the three functions area(), volume() and findSizesAndAxes() are independent and self-sufficient.
+Each of them converts the input model to SolidsShapeTypeModel if necessary.
+Were these functions to be called multiple times for the same model, this would be inefficient
+(the potential conversion of the same model would take place multiple times).
+
+To improve efficiency, these functions should not have the Model argument.
+Instead, another function should be introduced to set the model, the conversion to SolidsShapeTypeModel
+should take place in this function once, and these three functions would then always use the converted model.
+A similar optimization is already implemented in the ModelGeometry class that provides FramScript access to ModelGeometryInfo.
