What is supposed to happen if an invalid quantity is used? `verify_parse_operation("10 §§§")` or ``verify_parse_operation("10 $")`` verify_parse_operation correctly returns False but the Size_Quantity property has a value of "10 mm"....

I haven't yet checked the links you posted. It seems there is a bug in the quantity parser of the core system. When I write `App.Units.parseQuantity("1$")` then it correctly raises...

I can't give a qualified answer about whether these classes are needed or not as I don't know much about assemblies and their requirements. But for the new code you...

``` // clang-format off // inclusion of the generated files (generated out of AssemblyObject.xml) #include "AssemblyObjectPy.h" #include "AssemblyObjectPy.cpp" // clang-format on ```
