Bad export - nigec - 04-08-2020
I downloaded the Pearce 1931 model as lwo
http://www.dmi-3d.net/modelscar10.html
First thumbnail on that page
It imports into W3D no problem but fails totally to export as obj, Wings just freezes totally, I left it 10 minutes and it never recovered.
Exporting as 3ds, only a small section exports and you can not re import back into Wings (as 3ds)
This is the error:

dae fails to import into Sketchup
RE: Bad export - micheus - 04-09-2020
nigec, usually this behaviour has some relationship to the model topology.
I download the model and as it is a very densy mesh I just took a look at the edges length (Select->By->Edge Length).
There is a lot of very narrow faces in the back door's handle - 0.00005 wide only and 0.013 long. This very tiny number can bring problems to wings.
I can say you it's safe to use only four decimal digits values. So, after checked the small values has five decimal digits I just set the Export Scale on the OBJ exporter dialog to a value of 10.0.
Here is the result using Assimp:
That should fix any similar problem with you can have using third part objects that very detailed and small.
RE: Bad export - nigec - 04-10-2020
i was already exporting as scale 10 (exports are tiny in sketchup) but I have managed export it now
thanks I see what you mean about this model being rather dense in places, it'll export to Kerkythea perfectly fine
