for occurrence classes without special type.
E.g. previously:
you select IfcSlab and change it to IfcRoof - since there is not IfcRoofType in IFC2X3 it would figure the matching product type is IfcBeamType and change this slab's type element to IfcBeamType. IfcBuildingElementProxyType seems more generic and fitting.
E.g. you select IfcSlab and change it to IfcRoof - since there is not IfcRoofType in IFC2X3 it would figure the matching product type is IfcBeamType (which is confusing too but that's another subject) and change this slab's type object to IfcBeamType which consequently change IfcSlab to IfcBeam instead of IfcRoof that was selected originally.
Noticed investigating #5918
To support obtuse x_angle a refactoring had to be made, which helped
improve the general code for slab addition.
This is challenging because there are a few features that interact
with each other to create slabs, like `depth`, `direction_sense`, `offset`
and `x_angle`. In addition, these interactions can happen in different parts
of the code. This refactor improves the coherence between those different parts.
Files changed:
- `api/geometry/add_slab_representation.py`
- `model/slab.py` - inside the function `change_thickness()`
File to be changed in a following commit:
- `model/wall.py` - inside the operator `ChangeExtrusionXAngle` - To-do
1) Add default values for new IfcSurfaceStyleLighting so they won't appear invalid.
2) Temporarily disable starting surface style with a texture style since it requires additional texture UI to be exposed or some default texture to be assigned to keep it valid.
1) `do_not_delete` performs best when it's set
2) also_consider when `element` related elements go first, so there will be no need to traverse all other elements to see if they cover `element`'s inverses.
check schema version instead of accessing attribute directly (hasattr under the hood is just doing getattr and checking whether it returns AttributeError), so one less IFC access
Similar thing with element.Item to access IFC just once.
