Removing hidden edges on wireframe architectural model

[Ignas van Rijckevorsel]

I need to make a wireframe rendering of a building for a job. I’ve been given a model of the building, but it’s really messy, extra edges everywhere!

Using the “Melt” function I’ve been able to remove alot of the messy edges.

(img 1, 2 & 3)

But somehow I’ve found hidden edges within some surfaces which I can’t
remove . The edges don’t show up in the Constant Shading (Lines)
display, in Gouraud shading they show up like this: (img 4)

I can’t select these edges to remove them.

using the Cel Renderer to render the wireframe, all the weird hidden edges render as lines: (img 5)

This shape should be one whole surface without all the extra lines.

What are these strange edges and how can I remove them?

I have tried subdividing and a few other functions, the same also happens using the Sketch and Toon render effect.

Any ideas?

Thanks already in advance!

Cinema is drawing those extra lines as the surface is nonplanar and there are tons of extra points across the top edges. It basically needs those edges to be able to render/ draw the polygons or n-gon as it is. If you use mesh checking ( in the attribute manager menus) it can highlight issues. I think you’ll have to re-top it, the poly pen is great for this.

Don’t use edge. Go with 0 degree crease or border and use explosion modifier with 0.01% strength to detach object by faces so it can be rendered as faces without hidden edge showing.
