Part Thickness Limitations
Part Thickness Limitations
(OP)
I am building a part model of a PCB (printed circiut board) in Pro/E, and need to model individual layers so I can included the stiffness of my ground planes when I inport it into Pro/Mechanica. The PCB is about 9.00" x 15.00", so it is a simple extrusion. However, when I type in the thickness of 1 ounce copper (.00135) for the extrusion depth, it balks and won't let me go any lower than about .003". I tried extruding teh part 1.000" and then subtracting .99865" away to leave a .00135" thick part, which it will let me do, but them there is no model left over.
Is this an inherant limit in Pro/E, or is there a setting I can change to go to a .00135" thick part?

For circuit boards you will probably want to convert to absolute accuracy and set it smaller than your .00135".
I think I would set:
enable_absolute_accuracy yes
default_absolute_accuracy .0005
Or create a start part with those settings.
