Hiding layers of worksession links gets lost when the file is closed. Would it be possible to by default for Rhino to remember which layers where changed/hidden. I applies to both worksessions and linked blocks.
Sorry, I realize that’s a poor explanation, but not quite sure how to describe it.
The state of the layers in the files that are involved in the worksession is saved in the worksession file. You need to make sure to save that before exiting Rhino.
