There is a bug in TBC, since quite a while, that prevents often to create vertical lines with only 2 vertices. It will work if I draw the line further to another node, but I don't want that. The linework in the sample comes from an exploded IFC-object, and for structures I also don't want to start nudging lines. 2 node vertical lines must be possible.
Sometimes it works, sometimes it doesn't. No idea at how many decimals it looks, but if I enable 6 decimals the lines that work still show the same XY for the two nodes.
