When receiving input from a .dgn file a lot of it's parts are seen as Lines (That is how Smart Solids appear in it, almost as a WireFrame), I managed to group them and I am trying to build areas from them which I can later pass to a MeshBuilder.

Some of these lines seem to form perfect forms, just as I wish but some are deformed despite the wireframe looking just as good as the others.

I am grouping my lines by igds_cell_sequence_number, which gives me sort of individual elements like walls/windows/etc. as a wireframe:Then I pass it to an AreaBuilder

But my output looks like this:

It seems to connect just that triangle over there, how could I change this?

Or any idea of a different approach would be greatly appreciated.

Thanks in advance!
