Perhaps this belongs in a Microsoft forum, but maybe someone has had the same problem.

I cannot import a model directly from Photoscan into a office program (Word, powerpoint). "An error occurred while importing this file C:\model.obj" is the error message.
I have tried all different export options (I think), but always fails.
And if i import into Microsoft 3D-builder it finds some error with the model and wants to repair it. After the repair I can export it, and then import into office with no problem.
Any help apriciated!
