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.
