Keeping pro e assemblies when rendering in another package

I model in pro e wildfire 2.0. I have one major issue though. Ive found that there is no simple way to export my assembly model from pro e into a suitable package for rendering.

So far I have managed to export into image studio via step or IGES but I need to make better quality renders so I have started to learn rendering through Cinema 4d and maxwell studio, and I hope to start learning 3ds max anytime soon. I cant seem to export my assembly with all its parts into these packages while keeping all of the parts seperated, i.e. keeping all the parts within the assembly seperate so I can apply materials easily to each one or edit positions.

Does anyone have any advice because I really need it.


I’ve been using a program called PolyTrans. It allows me to import a pro assembly directly into Maya for rendering with MentalRay. I think the basic program will get you into 3ds format. I had to get an upgraded package for the Maya transfer. There is a link here. I should mention that I have never actually used the program itself. The Maya transfer happens internal to Maya, so I have never actually waded through Polytrans. It should be easy enough, but I don’t think I would try to model in it or anything… Good luck!

Just export as an .obj. format. Only thing is that you need to assign different colors to different parts in the assembly. Imports into almost anything since .obj is so common. The different colors should key each component so that you can assign separate materials.

I do this with Maya. Works fine. Here’s an example from some time back: reBang - mixed reality design .

save it as a part file.

many rendering program recognize seperate bodies within a part, but not parts within assemblies…save it as a .prt, then from there save it out as an .setp or .ges


You can export the assembly as a STEP to alias image studio and it keeps all parts and recognises them inthe part select panel. You can then drag and drop or assign different appearances to the seperate parts or sufaces.

Cheers, for the replies guys.

Ive been experimenting a bit and found that .obj into Maxwell Studio works a treat provided I limit the chord length, but even so I found that elipses and cirlces don’t come out perfect. Also, IGES and .stp files work good in Image Studio but there is no way I can get those formats directly into Maxwell Studio.

Ill try out the polytrans but it depends on how much it costs to purchase, but I have heard that is good.

Csven, how did you get the surfaces so smooth, what were your settings when you exported as a .obj?

Same as if I was kicking out an .stl file. I vary the settings to get the best triangulation. For this model, I forget the tri count but it was probably around 500,000 or so.

Ive tried using OBJ and this is what I got, quite a bit of tesselation around the edges as you can see best in the bottom right. Anyone got any ideas?
Ignore the scene set up, Im still working on that to make it brighter and clearer.

I would check the settings in 3DS or whatever you are using to render. I had the same tesselation problems importing assemblies from SolidWorks into Maya. It ended up that I had to adjust the tesselation settings in Maya to fix it.

Problem is that wehn exporting from pro engineer as an OBJ you only get the chord length and angle control settings. I dont think there are any other settings I could adjust to get a better output.
