Now i did use my better construct about this vase.And it works perfectly.Just i found too the problems you describe but not for in such a accurate way.

Yes thanks i fix my writing here now. the 4.4mb file is good enough.The first file i upload but have to leave the house in a hurry and drop my notebook into Resume but the upload maybe was not finished.Back later i upload another file because i check for make/Add Face.

edit : and it looks too that it miss some formatting about colors(and i did remember wondering about that i get this white meshes).
Because of selection of meshes i did start using obj some time ago
