- a file should remember the last chosen layer to put the “main/hidden” lines on
- sometimes quite clearly visible lines get onto the “hidden” lines layer and vice versa
the command remembers output layers but this info is not held in the file- is that info is not currently saved in the file but rather for Rhino in general. Do you see that or is that also not being remembered?
If you can send an example when you see this (here or email@example.com) , it will help us figure out how to avoid this, at least more often.
