I know the accuracy is even more than a micron, but how do I change the settings that I can work with such a radius?
By the way: Points instead of units would be fine too as long as the relations would be correct.
Thanks!
As of right now, from a GUI users perspective one can not adjust either the units or the maximum precision (number of decimal places) of the the gui input fields.
However FreeCAD can already make these parts (at 0.001 size box for example), if you enter the data via the Python command line or by running a script/macro.
For example if you create a new macro, paste the following into it, run the macro, then hit "zoom to view all" you will see a box 0.001 cubed.
Code: Select all
from FreeCAD import Base
from FreeCAD import Part
bb = Part.makeBox(0.001,0.001,0.001,Base.Vector(0,-2,0))
Part.show(bb)
You can also translate Units with a script.
If you only want to use the gui, then the only thing I can suggest is that you scale your whole model, e.g. multiply all dimensions by 10.
After 0.13 is released we could consider how to change these two issues, if there is enough interest.
