https://community.graphisoft.com/t5/Archicad-C-API/automation/m-p/717273#M11050 I am trying to automate the creation of a door threshold based on the floor elevations on either side. I have successfully retrieved the elevation data, but I am struggling to create a virtual axis by clicking two points—and then automatically drawing a perpendicular threshold centered on that axis. Could anyone help me with this part of the code?
