I wonder wich program save as .nx3
I know is a CAD platform and probably created in u-g nx3 (unigraphics nx3) siemens cad platform.
the problem is u-g nx8(last version) or nx3 save projects as .prt not .nx3
Well the .nx3 files are used to create a body with 2d textures (.dds). is also called for that a jointer.
So wich cad program, tool anny... can open .nx3 files, or better wich soft can save a model texture as parts (dds) and joints (nx3)
