Long time Rhino user, new forum member.
I have a question about a file that I am working with right now. It is opening so incredibly slowly on my machine even when I am working on it from my SSD. Sometimes is takes as long as 5 minutes or more to open or will simply lock up and I have to close Rhino and start again. Is there somewhere to submit files for testing? Or a way to inspect it for why it is so slowly beyond the Audit command?
The file is only ~270Mb and I have had files over 1Gb that have not been as bad to use. It does make heavy use of block instances (which is the only real difference from my usual workflow), but I had set it up that way thinking that blocks are lighter in terms of memory usage.
29 instance definitions
10 dimension styles
249 rendering materials
44771 normal objects
0 locked objects
0 hidden objects
0 deleted objects (in undo buffer)
8072 block definition objects
0 reference normal objects
0 reference locked objects
0 reference hidden objects
0 reference block definition objects
The only other thing that I can think of is that there is a lot of imported GIS and AutoCAD linework that is perhaps causing problems. I have just purged the file, saved and reopened and it hasn’t helped. While opening, it shows Rhino using about 10% CPU and ~6Gb of ram.
