How do I draw tiny circles?


I am trying to draw a profile that includes a very small radius. When I key in the radius (0.15 mm) I get an error pop-up “Radius is too small”.
I have tried increasing the precision in Window/Model Info/Units, but that has no effect.


Work at a larger scale and scale down when finished.
SU has problems forming tiny faces, but they can exist.
When working on small things in metric it is often easier to work in meters so nothing is smaller than a mm.
Once you are ready you can then scale the whole thing down without issue.


Ah! That makes perfect sense! Thank you so much!
