difficult geometry

[raymarcher]

I have imported a model from autocad that is difficult to cleanup, see the screenshot attached, I have double faces and flipped normals.

 

With xview i can highlight what needs to be flipped with face orientation, but I can't transfer the highlighted faces to a sub selection.

Hi,

 

First, weld all vertices. Then transform your mesh in poly edit (faster for rendering)

 

I would simply use a 2 sided mat. It will do the job.

Have you tried unifying the faces?

[postite]

You could try this script:

I tried that all before, if you have the time, here is a sample from the terrain, with xview you can highlight the disoriented faces, good luck

Heu... I do not have any problem rendering it...

 

Simply Arch & Design material with Back Face Cullin unticked.

Bonjour postite, I should have explained it better. I want to add a turbosmooth or a simple smooth modifier with it, for that you need welding, and for welding you need to have an uniform face orientation.

Salut raymarcher

 

Your mesh was really stinky!! I used a topography software to re-generate a new proper mesh.

Hope it helps

Out of curiosity, what program did you use to clean up the topography?

[raymarcher]

Well done, I am curiuous too, greetings

[postite]

I did not clean the mesh but re-generate it.

 

I imported your mesh in Mensura Genius 2008 to generate a 3D mesh based on the existing vertices then export in dwg.

[raymarcher]

Hello postite, I have mensura at my disposal but am not expierenced, could you explain step by step how you converted the model from max to mensura so

I can get this quickly done?

Here is my detailed workflow:

 

1. Do a "Create shape" in poly edit mode with all edges selected sothat you have a spline network.
   
2. Delete the old mesh and export the spline network in *.dwg
   
3. Open Mensura/ New project
   
4. Link a dwg (the one just created before)
   
5. Module/ Land (new window opens)
   
6. Open the layer manager and with the green arrow import all layers from your dwg to this project
   
7. Land/ Create land (or something like that) (popup appears)
   
8. Click "OK" (popup closes)
   
9. Right-click in the scene (contextual menu appears) click "All"
   
10. Then push "Enter" on your keyboard and it's done
    
11. File/ Export to dwg
    
12. Import in max
