Complex very small scale .dxf's to Pro-E part

Hello All, New job and a new challenge. The gEEk creates small micro-wave components on alumina substrates. He has no concept of physical reality (he just designs to what works on his simulation package, and sends the result). I'm taking his .dxf's, dropping them into a drawing, and using the drawing to create part section. I need to deal with very small geometries and accuracies (1E-05"). These sections are not stable. Any ideas on how to pick and manipulate this geometry 1:1 w/o the possibility of feature shifting? Thanks to all. Bob Fleming

Something like Duroid 6010?

Sounds familiar. No clearances anywhere, IOW. What dumbass "geniuses": the companies they work for foster this by providing minions, cad monkeys who scurry around cleaning up the "advanced" ones' droppings.

Why DXFs!?! Their version of CST Microwave Studio doesn't have any solids translators? Not even SAT? Dumbass and cheapass: not a charming combo!

First, DXF is units insenstive. Accuracy problems will increase if your default units is inches and you're getting exported files in mils, the typical board design units. Get them to set their files up, even temporarily, in inches and then export. Or, get them into a part with a custom units in mils then use this for your drawing. Most people don't realize that drawings in Pro/e are incapable of setting, scaling or interpreting units, meaning both ends of the communication process are lame. Drawings take their units exclusively from parts/assemblies. So, while in a drawing view, you may be able to scale geometry to fit on the sheet reasonably well, the whole business of accuracy is totally cocked up. But, mainly, I'd recommend trying to sweet talk them into exporting solid geometry (in the spirit of science, in spite of the fact that the otherworldly "genius" knows everything). The janitorial work doesn't decrease, but the ability to deal with it increases.
