Currently it causes an error if you run it in object mode and doesn't really work in edit mode either because you may have no vertices selected. Will fix soon.
Now it's possible to set custom markers in section annotation.
To do so you need to add BBIM_Section pset to the annotation and then you can either toggle displaying some marker with ShowStartArrow/ShowEndArrow or you can write the id of some custom symbol in StartArrowSymbol/EndArrowSymbol (need to make sure the symbol is included in symbols.svg).
Other changes:
- removed vertex sorting in decoration.py so that start and end points will be the same thing both in svg and in viewport representation (previously the sorting was needed of the direction the arrow in shader wasn't inverted));
- fixed bug when in svg section arrow symbols wouldn't rotate if you move individual verts of the annotation, not the entire object (I guess this bug sneaked in after adapting elevation annotation)
Here's the example - https://i.imgur.com/db09OVF.png
To make it work need to add BBIM_Section property set to the annotation and set "HasConnectedSectionLine" to False (by default it's True).
Also added preview for this feature in viewport.
Otherwise it always returned a list with 1 empty string like `[ "" ]` which resulted in messy class names in svg like "-87IfcAnnotation0LtaLiEpzAOxEqmIvCV27EFALLSLOPEANGLE".
Added fall annotation - they appear both in viewport and svg.
There are three types of annotations (SLOPE_ANGLE, SLOPE_FRACTION, SLOPE_PERCENT) you can switch them by changing annotation's ObjectType to one of those values.
By default it uses angle representation.
Small fix to allow setting cad_tool even if operators were called not from viewport and to avoid warnings like "Warning: Tool 'bim.cad_tool' not found for space 'PROPERTIES'"
Changes:
1) Added editing railing / roof path as hotkey to bim / cad tools.
2) Added profile decorator
3) Some switching modes and tools for convenience
4) Fixed nasty bug in tool.Blender.apply_bmesh - method wasn't updating current mesh if it was in edit mode.
Added Ifc Roof modifier (also added it to shift-a menu and type manager). It works similar way to railing modifier - you define roof profile and then roof is generated.
Currently it has only 1 type of roof - HIP_ROOF (it utilizes bim.generate_hipped_roof operator).
