Hi everyone,

I imported a simple building geometry from Archicad (here is only one wall as an example) and I don’t know how to solve this issue in a simple way. In the first picture the wall is shown, in the second, if I move a vertex, there is a weird polygon in the back meaning that there’s something wrong and the vertex doesn’t belong to the edge I’ve moved it from. The wall has 0 thickness, so there’s no back polygons - IF I edit poly and click on the wall to select polygon, there is only one, after deleting it, the wall disappears.

If I select all vertices and let the Max weld them, it doesn’t help.

I can’t leave this geometry this way as when I import the file to Perpakura software as is, it cannot handle unfolding geometry in the right way - there’s no windows in the final effect.

I know I could cut the polygon to support each vertex, but it’s too much work.

I need to have it done in all walls (quite many of them). Is there any quick way to solve this problem?

Thanks in advance.
