Why do the models, converted from solidworks, have such terrible wireframes? What can I do about it?
Check you Tools/Options sketch display settings - could be you have a different template your pulling from when generating the models...
John, I primarily use other packages with solidworks. Therefore I have to convert the files to OBJ. When I do and view the wireframes, they are always in very poor condition (ie. unwanted hard edges, overlapping cv's, poor tessellation.) Any guidance is most appreciated.
I don't know much about OBJ files, but is it possible that the "resolution" of the file is based on the part's display resolution before it was translated? IFC files are like that.
If so, then you can change your display resolution here:
Try it out.
Thanks Dan, will do.
Michael, a little off topic but how exactly do you convert your files to an OBJ? I only ask because it's not a standard format for SW (at least not on export) and it makes me wonder if you couldn't mess with the settings for whatever format you first save it out in. Of course this is moot if you have an add-in that allows you to save-as an OBJ, but just curious.
We are a graphics division within a large manufacturer. We take the Solidworks files, assembly files, etc and bring them into SolidWorks Visualize Pro. There we export to OBJ. I realize this is not ideal and I am wondering if there is another way that would have better results. We use both Autodesk Maya and Autodesk Softimage as well. We are producing visuals of our products for primarily marketing and advertising purposes and most of our "higher-end" work is done in Maya, Max and/or Softimage. My priority is getting the best working file (clean wireframes) into one of these packages. BTW, I am not actually Michael, My name is Scott Lange and I am a contractor working for Toto.
Thank you for your time and attention.
Might be good to submit you question here:
Free Solidworks OBJ Exporter v2.0
You might try this above ... I have not used it much myself so I don't know if it improves on the existing tessellation settings.
Actually, nurbs to mesh conversion is poor in many cad applications. If you need to do this on a regular basis, I suggest looking at Moi3D. According to many users, it has the best mesher for cad models producing mostly quad output which is great for rendering. Its an inexpensive application and is developed by the same person that wrote the original Rhino.
Thank you, Chris. I will try this out.
Chris, is this still viable in the current Solidworks version? I am asking because I am "adding" it to my Solidworks Macros and it won't "open".
Check the video from that post on how to setup and use that macro.
Thank you. It does help a bit but doesn't really solve the primary issue, which I have come to find out, is a rudimentary issue regarding converting a spline-based model to a poly model.
I suspect that the problem lies in the settings for the conversion utility you are using for creating the OBJ files, not Solidworks.
Does the utility give you options for max tessellation angle, max chord deviation & min face width?
Are you doing this via a STL file exported out of Solidworks? If so, what is the stl resolution set at?
One issue is the the triangulation method is prone to rendering artifacts. Long, spikey, triangles can produce rendering artifacts and SolidWorks does not give any control over the aspect ratio of the edges.
Another issue is crease angle, which tells the renderer to smooth shade or not smooth shade a particular edge, these are not present when exported. Not all formats support this but OBJ does.
