Delete hidden geometry

[Boein]

Hi all,

After importing a dxf file (coming from an exported floorplan drawing) in sketchup2015, my model had a lot of X's. It looks like every endpoint of a surface/shape was joined by a line during the import. So I had to remove a lot, and a mean really a lot of those lines. Removing them was sometimes dangerous, deleting the wrong line could delete a part of a surface. So I used the smooth edges tool, clicking on the line and using the smooth edges, removed the line and the surface divided by the 'cross' became again a plain surface. But I didn't know I was not actually deleting the line, just hiding it. Using the show hidden geometry option makes them reappear, and I guess those lines have an impact on processing although they are useless. If using the "show hidden geometry" can show these lines again, I guess it must be possible to create a ruby script to only delete those lines? Anyone knows how?

Sounds like the faces are triangulated.
Get thomthom's CleanUp toolset from the PluginStore.
That has options to delete edges making coplanar in faces [merge-faces?].
Thus undoing any unnecessary triangulation.

Alternatively switch on Hidden Geometry, Edit>Select-all, then copy+paste this snippet into the Ruby Console + <enter>

model=Sketchup.active_model
edges=model.selection.grep(Sketchup;;Edge).find_all{|e| e.faces.length == 2 }
togos=[]
counter=0 
model.start_operation("Delete Coplanar Edges")
edges.each{|e|
  next unless e.valid?
  if e.faces[0].normal.dot(e.faces[1].normal)>0.9999999999999 && e.faces[0].material==e.faces[1].material && e.faces[0].back_material==e.faces[1].back_material
    togos << e
    counter+=1
    Sketchup;;set_status_text(("Coplanar Edges Erased = #{counter}"),SB_PROMPT)
  end#if
}
model.active_entities.erase_entities(togos)
model.commit_operation

It is one step undo-able...

Ok found it, I installed the thomthom's CleanUp toolset and using the "merge faces" did the trick (5119 faces merged). Saved me a lot of work thanks for the suggestion!
