What would be the best strategy for this?
Did anyone try a 3D probe? Is it more precise than using dowels?
Absolutely not. One thing you should keep in mind is that imported stl/obj files are converted into a pixel based representation. Therefore you can lose some accuracy in regards to size and thickness, also any features within the part. There is currently another thread active that discusses this situation.
Back to the dowel locating. It is a very good method of locating parts.

I will be using another software for tilting the spindle on the 4th axis. This is how the piece looks like with side support for dowels and bridges/tabs:

Is the stl/obj importing issue something related to vcarve or something in general in all softwares?
It is related to the conversion between a vector based file and a pixel based programming system. Think what happens when you convert a vector drawing to a raster drawing....some portion of the pixels are either over or under the line. Just the nature of things. I think I can safely say that Vectric's target market is not the precision machining industry. The programs that do that work directly with the mesh. The advantage Vectric has is when working with organic/artistic things. Those are miserable to do in more mechanically oriented packages.
Did anyone try creating a negative of the piece that acts as a support for when flipping the piece? Would that work?
