Can you send me the simplest non ifc related code that fails? Would make it easier to debug. I honestly doubt it is a bug with Topologic because the same call in sverchok python code is working fine.

I will soon but you could also look at the python behind that node and see how to call that method. If it works in sverchok, it will work in a python script.

@topologic Sverchok node are fine. I have problems using this method in a script.

@agonzalezesteve I just tried it in sverchok and Face.AdjacentCells worked perfectly. Here is the screen shot. Notice that it produces the two cell (in stethoscope) when the middle face is asked for

I have decided to expand the beta testing of Topologic-Sverchok for Windows. This version is supposed to work with minimal additional packages. Please test and report back any success or failure in ac

Topologic also doesn’t depend on blender. It can run as a python module from the console. Topologic-sverchok on the other hand runs with Blender.

@JanF yes you can group sverchok nodes into a custom node and choose which parameters to expose.

@stephen_l i don't think it is very different from normal programming, in more complex projects you simply have to divide it into smaller blocks (but you're right, as far as I know sverchok lacks gras

You can then download and install the Topologic Sverchok nodes, but there is currently some Windows code that prevents it from running, edit ~/.config/blender/2.93/scripts/addons/topologicsverchok-mai

As a small standalone business, Geometry Gym has no resources to donate to a Sverchok port at this point in time.

Well, ping @geometrygym - what are your thoughts on a Sverchok port?

@JanF and @kaiaurelienzh great! Have either of you used GeometryGym's IFC nodes? If you get familiar with it and are able to demonstrate how to use it to me, I can replicate that behaviour in Sverchok

I am currently trying to learn Blender/BlenderBIM and Sverchok. I come from Grasshopper background so would be happy join in on this initiative and help out in some way.

I'm packaging the Homemaker add-on here, but the problem will be the same with any other add-on that uses Topologic (such as the Topologic Sverchok nodes).

I am happy to announce that the porting of Topologic nodes to Blender/Sverchok is now complete! 194 nodes! Truly enjoyed this journey and still lots more to do:

So did anyone try to actually build ifc files with the sverchok nodes? What am I missing? I'm simply trying to create a wall using the sverchok nodes only. I have two problems:

I will try to visualise it using Topologic-Sverchok. Stay tuned :)
