hi,
The best solutions are cad technics for the industrial models.
In fact maya supports cad technics
For the ýndustrial models I offer you only nurbs modeling.
Never use poligon and...

You can use duplicate than snap to point commands
or you can write simple short mel command
Of course you must turn on CVs "nurbs compenent" at display pulldown menu.

Yes, discusting problem,
Solution:
change value 0,001 Tolerance at "round constant radius history"
and
change value 3 and 3 U and V division factor at "tessellation"

Enjoy....
