Hi Nathan, I am not a BRL-CAD developer, but I have used it for a long time. I personally do not know of a way to adjust that limit. To me, the easiest thing to do would be to scale up your model. If you are modeling a nm scale object, apply those values in a mm scale. Then it is just a matter of decimal placement.

I read in regards to the end-points of the PIPE primitive: "Points may not be coincident; they must be offset by at least 0.0001 mm." so I'm confused with why the PIPE command has this constraint, when I've read in BRLCAD docs something like it supports 'from subatomic to galactic' scales with perfect representation. 100nm is larger than the smallest thing I have plans to model (nanofluidics), can I somehow reduce that 0.0001 number (is it some macro or hard-coded value?) or do I have to write my own PIPE-type helper function that joins cylinders and torii?
