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.
Fixes mapping of vertical alignment parabola business logic to geometry. Adds creation function of h and v alignment. Adds stationing referent at start of alignment. Fixes utility functions
(I hope I don't miss anything, no tests seem to fail and performance is increased significantly) but because `subelement_queue` initiated with the `traverse` all `element`'s subelements will be traversed inside `while` loop twice - once as a part of initial queue and another time when `element` is traversed inside the loop and all those elements added to the queue again.
Now we just initiate the `queue` with the `element` and it will be traversed inside the loop like any other element.
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.
1) replaced walk with traverse(max_levels=1)
2) early return if there total_inverses == 0
3) early return if also_considered_inverses is enough to cover total_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.
