You want quad exports from SU into Blender?

Ideally I'd like to model in SU as I have always done and export to Blender so that I can use the mesh from SU. I have tried converting models in SU to quads but that does not work great and I have tried converting tri's to quads in Blender which also does not work great.
-
Can you PM or share a file?
I might have a workflow but since I mostly model in Quads I'd need a dirty mesh to test.
If it's something's with n-gons forget it as that's just a recipe for disaster.

Having exported many SU models to Blender over the past year or so, I've found that if the mesh doesn't convert to quads well in SU (I use TT's Quad Tools) it's not going to convert well in Blender. The same errors that you find in the SU model will show up in the Blender conversion. You do need a very clean and logically constructed model to make use of quads in Blender.

This video by Peter Guthrie shows his workflow from SketchUp to Max to have quads.
I guess it's similar to Blender.This also led me to this idea for a SketchUp plugin: http://sketchucation.com/forums/viewtopic.php?f=323&t=54677#p495930

Nice work on the plugin
I've been doing that manually for a long time, nice to have this automated. It matters a great deal if you are doing displacement or want to modify the mesh in any way (soften corners, etc.)However - n-gons are perfectly fine for architectural work. Those planes will render as planes regardless of the orientation or subdivisions of the mesh. For building models, I just import the whole mess into Blender and never have to bother with quads. (the only exception is that I still do tris to quads to simplify the mesh, and always remove duplicate vertices.) For windows it does matter because you need proper geometry to get refraction correctly.
Another thing to note - mirrored components from SU will end up with reversed normals a lot of times (wrecks havoc on windows and refraction
). I'm wondering if it is worse with nested components though, may need to test that further. -

I may have a solution to my mesh problem
-
I have that tool. Not really gonna work completely.
-
Rich, I pm'd a model for you to test.
I was reluctant to send before as I assumed you may be a little busy and knackered after the arrival of the boys.
-
Won't get at this short term. But will defo take a look and pass on whatever info I can.

Retopology tools have a different function than I think you're looking for. Create a high detail (high poly) character, texture it, light it, etc. Then bake all the maps down. Then 're-topologize' the high detail model with the retopology tool to make a low detail, low poly version and then apply the baked map to it. The result is a character with the visual look of the high detail model but having a small fraction of the poly count of the original.

What I was trying to do is get some of my SU created cartoon characters which are very heavy in SU into Blender cleaned up, rigged, posed and then 3D printed.

Hi,
You might be better off not trying to clean your mesh but just build a retopology on top of it even if you are not planning to bake maps. There are a few options, looks like you have found one of them, another is a shrinkwrap or bsurfaces but the failsafe way is just to use the snapping tools. I have done this a few times with MOI and sketchup models to build a proper deforming mesh for animation and doing the retopology allows you to concentrate on edge flow e.t.c.
Slow at first but done enough times it speeds up, just like anything, especially with the looptools and F2 addons.
Hope this helps.
Regards
Sam

Oh. My misunderstanding. I thought the comment was about architecture, which would be a lot of work for a retopology tool.
-
Hmm ... but if your end point is 3D printing I would think you're going to lose a lot of detail with a retopology tool.
But, aside from the issue of SketchUp to Blender, if you're talking about cartoon characters, you're going to love sub d modeling once you get the hang of it.
-
If detail is what you are after you can use a multires modifier and shrinkwrap on the retopology. shrinkwrap setting project positive and negative.

I have just learned about retopology and when to use it, interesting stuff that. So much to learn....
So here I am thinking Z-Brush is the king at sculpting, and just discovered Blenders Dynotopo, WoW!!
Blender is awesome.

Blender sculpting methods are competitive to zbrush ones.
If this statement sounds like fanboyism you have to check it first.

http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.66/Dynamic_Topology_SculptingI have seen a lot of your sculptures on Blender, I'm very interested in the style you use, not sure if you are using some sort of displacement brush or new method, got a link to a tutorial? Those scifi looking things (do not know what to call them as they look like organic space ships)
