Hey Guys!

I've got a big Problem with Autodesk Maya.
I have a .stl File (3D-Scan), i've converted this File into a .obj (in another Program).
But when i import the .obj File into Maya, i can't see it.
If i press "F" i can see the object for a second, but then it disappears.
I don't think it's a Clipping Problem, because i've set Near Clipping to 0.1 and Far Clipping to 99999.
I hope someone of you can help me.
