I want to use wings3d as 《Creo》 an extension , because there some lack of《Creo》 in the polygon modeling function， 《Creo》 used to exchange the polygon file format is the obj format, if Creo file simply, wings3d is no problem, but if the Creo file is more complex, Wings3d will bring problem. Creo has no Problem with other software (3DMAX, Maya).
I find that error come from here:
If there are multiple independent geometries in Creo，the error will come。
and if there only one geometry in creo，the error will disappear。
