3D dwg export generates many polygons

Anonymous

Hi.

When I'm trying to export our building as 3D dwg our slabs becomes a mess. As we have a lot of holes through the slab archicad generates polygons across the whole slab when exporting to 3D dwg.

Any tips on how to get clean 3D outlined slabs??

Why wouldn't you want the holes you've placed to be exported?
What is the purpose of your exporting the slab with no holes in it?

We do want the holes but there are a lot of unwanted polylines that covers the surface like a morph before hidden geometry...

That the round holes become faceted when saving to a 3D DWG is normal, see screenshot. The mesh like lines on the surface, if I understood you correctly, do not. Can you post a screenshot?

I had some issues trying to post a an image from my dropbox (as I can't create a public folder I dunno how to make it work) . So basically if you would have my problem there would be lines from the corners of the slab connecting to the holes.

Just do a screenshot and attach it to your post.

Wow, you have quite a few SEOs on that slab!
Some of them are affecting the slab height hence the many accurate contour type lines along it's surface.
You could try using a mesh instead of the slab. With meshes you can adjust the ridges from smooth to all defined. Perhaps that will translate with the fewer contour lines.

Actually there are no SEO. Also to be assured that there are no intersecting objects I've copied the slab so it's completely alone. I have also redrawn it using magic wand and it shows the same result.

I just found out that it works fine in archicad 19. I've checked both translators and they have the same settings.
