It's located in "Modifiers" section of the properties (the same way as IFC Array or IFC Stair).
It requires Sverchok addon to be enabled (it's lazy importing it when it's needed, so there is no new constant dependency).
What you can now do with it:
1) Add sverchok graphs to this modifier and store simple data from sverchok in IFC ("Update data from sverchok). The "output" node of the sverchok graph has to be type of "Viewer Draw" and it's name should start with "ifcoutput" (no case-sensitive).
2) Import/export json of sverchok graphs.
Fixed bug where the angle was drawn in svg only for the first two edges of the curve.
Now it takes into account all edges - first angle = edge0 + edge1, second angle = edge1 + edge2 etc.
Added ReloadSelectedIfcFile operator and added it to IFC Quality Control -> IFC Debug, it's useful when you're debugging and doing a lot of iterations on the same file.
Added c- and z-profiles with lips to IFC AU Steel profile library (based on data from https://github.com/boltsparts/boltsparts/pull/15).
For z-profiles I've created simple 2D curve generation function that can be reused later - it requires list of points and list of points with fillets and the results are list of curve points, segments and IfcIndexedPolyCurve.
Example:
points, segments, ifc_curve = create_simple_curve_from_coords(coords,
fillets = (0, 1, 4, 5, 6, 7, 10, 11),
fillet_radius=(r+t, r+t, r, r, r+t, r+t, r, r),
closed=True, ifc_file=ifc_file)
Added new stair type "Wood / Steel" to IFC Stair modifier. It's less sophisticated than "Concrete" stair type - it acts more like a "Dumb stair" operator we have.
1) Added "IFC Stair" to object modifiers - it works in similar way as "IFC Array". It creates a stair from current object (if it's IfcStairFlight) and writes it's parameters to property set "BBIM_Stair" and also to IfcStairFlight parameters.
Then you can edit it - modifying stair parameters and immediately see the changes, then you can save those changes or discard them.
2) "Clever Stair" operator (in Shift+A menu) works a bit different now - it creates new IfcStairFlight with IFC Stair modifier activated.
