Fixed by Kev33.
The newest version of Mesh viewer with fully functional wireframe and most of the errors fixed. 3D fuction and quick draw added. Point assistant and group assistant added for ship developers. UPDATE: Measure distance mode added and +/- values fixed. Sorry for re-uploading but I changed the author and it disappeared from my add-ons. (Screenshot from previous version)
Now with full instalation program there shouldn be .ocx files missing
