Hi
I have imported a 3D model from my client as dwg.
When I open it, I see a lot of invisible lines dividing the surfaces into triangles.
When I render with Vray and use a material with an outline applied, the invisible lines also render, even in places where there are no dotted lines in my SketchUp model.
I have tried removing all smoothness, but it doesn’t change the outcome.
What can I do to remove it - without rebuilding the model?
Thank.
What are the settings for the orange material? Does it have an EdgeTex?
ThomThom’s free Cleanup extension would remove the diagonals if the faces are truly planar.
Hi Mihai an Anssi
I have inserted a screenshot of the material settings but am not using EdgeTex.
I have noticed that when I explode the geometry and group it again, the geometry “changes” shape—it protrudes or “grows” in size.
Is this something you have seen, or know why?
Hi
I have solved it, but it is manual labor, so if you have a solution, please let me know.
The model is imported into the coordinate system UTM32 and, thus far, far away from origin 0,0.
I have offset the model closer to 0,0, so it is only a few kilometers from the origin.
The result is that the geometry is still “distorted,” and exploding the group and grouping again solves the problem but “changes” the geometry. The corners still display the same coordinates, so all should be okay, except that Sketchup can not correctly interpret the closed groups that have been imported far from the origin.
Is there a way to explode all groups and group them again automatically?
I have Chris Fullmer’s plugin, “Loose to Groups,” but because the geometry is touching, it creates one big group.
Below you can see that the group not yet exploded is “off” in position and will not allow me to select the exact position due to the exact position is “wrong” of the not yet exploded groups. If that makes sense!? 
Thanks
The information about how the model was created was important, and from the image it was probably arrived at after several guesses.
It is possible that the groups each have their axes positioned at a great distance from the origin and you can use one of the existing extensions to move them.
Yes, I see it is essential information, but I was unaware of it.
I am used to offsetting geometry more than 0,5 million meters in the x direction and 6 million meters in the y direction, but I have never encountered an issue where geometry shifts position visibly.
All the axes are positioned locally regarding the individual group.
If I figure out why, I will let you know.
This is a common problem in 3D - even in videogames of the game roles biggest entertainment franchises - costing hundreds of millions of $ to produce suffer from it.
Hi and thank you. Thank comforts me a bit in my struggle and tedious work cleaning up
