I can't sketch anything smaller than about 100 nanometers. Is it normal ? As I wrote in an old thread "Modelling space size" :
So I thought I could "easily" design sub-micron features, especially when setting microns, nanometers or angstroms in the document options, but it seems the workspace is "fixed" to a few cubic kilometers, limiting the resolution at the bottom of the scale... What limits sketching to 100 nanos while numbers would allow to go down to about 0.2 nanos ? What's the use of using angstroms as units if you can't use them ? Did I miss something ? For those who ask why I care : some swiss watchmakers model gears with a sub-atomic precision. The fact that atoms can't be cut in two flat pieces is considered as a machining error...
