Hello,
I am currently using inventor to design a piece fabricated by thin film technology (nanometer resolution). I have a structure which is 25nm thick (0.025 micron). Unfortunately, when I export it in STL format, the smallest tolerance is 0.1 micron. How can I change that? Is it possible to work with sub micro structures?
I need the correct dimensions, because I am doing a simulation in COMSOL using this design.
Thank you in advance for your help.
Best,
Julia
I've tried over the last few minutes to make a 25 nm cube with IV 2014 and I can't get IV to zoom in far enough to see any sketch geometry once I apply a 25nm dimension.
What settings have you used to create these small features?
I looked briefly in the IV help file to see if I could find a listing of the min/max feature size that Inventor supports, but I did not find anything.
I understand that STL files started out as a tool for 3d printing. Wikipedia's article on 3d printing talks about printing resolutions on the order of 10-100 micrometers. I don't think anyone spent any time making STL suitable for features 1000x smaller than the resolution of the typical output device.
You might try stp or igus files.

Hello,
Thank you for your answers!
So actually I made a mistake in my first post. I am exporting in STEP format (.stp). Truly sorry =/
Nevertheless, the minimum tolerance for .stp is still 0.1 micro (100 nm).
I tried to export in other file types, but none show what the minimum tolerance is. And when I try to import them back in COMSOL, I got errors, because of features which are too small. Any suggestions for the best export format?
Thank you again for your help and time.
