how do you rescale a model by exact measures because i don't know how. i can't print my model because the measures aren't good sow how do i make them good with google sketch-up.
i hope you can help me.
Grab yourself a copy of Accutrans3D or MeshLab and use their scaling tools. NetFabb can also be used for scaling, but it doesn't support .dae files, though it can be an invaluable tool for measuring & reparing models.
