Back [plane edges visible in Blender

[Ark Vuckovic]

Hello,

I've run into a problem while modeling a building  from AutoCAD floor plan. I'm using Blender 2.79. I imported the DXF file and build my walls, extruding a plane. When I extruded the walls on Z axes, I discovered that all my back plane edges are visible as you can see it on the snapshot bellow. Can you give me a clue on how to fix that?

Thank you.

A to select all -> Ctrl+N to make normals consistent.

Thanks for your reply. I tried it , but it had no effect. My solids look like they are in wireframe mode, but they're not.

So, did you click the little button that lets you toggle between solid and transparent viewing?

Of course I did. It just adds more visibility. Nothing else. You can see it on my snapshot that the button is pressed.

How do you expect anyone to guess the problem without seeing how the normals are facing?

Looked like inverted face normals but was actually a problem with clipping in the 3D editor when in Edit mode and Orthographic view. ( Was ok in Perspective view. ) Changing the Clip Start and End values had no effect.

The fix for the imported mesh ( from Autocad.Dfx file ) was the following :

 

 

 

Note: The mesh had been imported with the Unit Scale at 0.001 so that it would be the correct size in Blender, approx 13 x 15 x 4 meters. The working unit in Autocad must have been set to millimeters.

You gotta clean up that mesh friend. Why would you use autocad to produce game models? That's a completely different type of 3D model.

Ah wow, never thought of that. Good info, not much of an auto cad user minus fusion for specific things in 3d prints. Ty for this post
