I just imported an .dae file into Blender and I realised that all the faces are triangulated and the faces are separated.
I can fix this manually entering into edit mode, removing doubles and converting triangles to quads. The only problem is that I have something like a few hundred separate objects, so obviously, to repeat all this operations for every single object will be a very time consuming job.
Is here around a script or something to do all this steps automatically? Enter into Edit mode, Remove Doubles, Tris to Quads, leave Edit mode.
