Hey there!
I converted a cityGML file to 3dm and by default it looks like you can see in the first picture.
The buildings are individual meshes that all have these diagonal lines running through the main surfaces.
When I switch the view and hide the grid lines, the diagonal lines disappear and the buldings are displayed clean.
Now I want to deconstruct the building with grasshopper and want to work with these clean surfaces like shown before. How can I get these surfaces?
I tried things like deconstructing the mesh, converting to breps etc. but the surfaces are always split up. But the fact that rhino can display the buildings in a clean way proves that there is some differentiation between the vertices, otherwise it wouldn´t know which ones to hide or show.
I am using Rhino 7 btw.
Thank you for the suggestion.
Merging the faces helps but unfortunately does not go all the way. The picture I posted here shows three copies of the same building.
is the unedited mesh with hidden grid lines in the display settings.
is using AddNgonsToMesh
is using MergeAllCoplanarFaces
Like I said, it helps but does not do the full job!
