Rhino 6 suddenly hanging on simple mouse clicks and saves

Hi - I’ve been using Rhino 6 with a good Nvidia graphics card for a long time and suddenly the program is freezing constantly on simple mouse clicks, with delays of up to 30 seconds before the program resumes. The file is mostly 2D, very small, although I have a lot of empty layers set up. I have two image pictures in the file, but even with their layers off I get this issue. Never had this before. The screen says “not responding” then finally resolves. Additionally, I am working locally and saving the file (with so little geometry) should (and has been) instant but now it hangs for 30 seconds. Any thoughts on what could have changed and is causing this? Thanks, Matthew

Hello - please open Options > Plug-ins page and disable Mindesk, Enscape, Lumion, then close and re-open Rhino. Is there any change?


Thanks, Pascal. Unfortunately no change. Another example of the behavior is I create a simple 3D extruded box then hit save. It still takes 10 seconds to save (where previously it would be instant) and then after the save is finished, the workspace is frozen (no response to mouse or typing) for a few more seconds before finally “releasing” and allowing new work.


Hi Matthew -

How suddenly? did you make any changes to the system or install a plug-in or anything that you can recall that corresponds to this, timing wise? Does it happen in any file, even a new one started with ‘no template’?


This started happening last week. I can’t think of anything that I’ve done differently than in the last many years. I did just try creating a very simple completely new model and with just a few 3D boxes there seems to be no issue. So I guess there may be something corrupt with the file? The only possibly unusual thing is the use of inserted jpgs as pictures, and the fairly large layer list (relates to a grasshopper script).

By the way, an additional (presumably related) issue is when I simply select some geometry in the file and hit control C to copy I get the 5-10 second hang up.

I’m thinking the issue is the embedded bitmap. I imported it as a picture and the originating file is on a remote server, not local. I’m thinking that the issue may be both the bitmap file size and its remoteness. Question: when importing a bitmap as a picture, does it remain as a link to the originating file or get embedded in the local rhino file? Also, is there any difference in this regard if I import a ‘picture’ as opposed to drop a bitmap from file manager onto a rhino surface? Thanks

In rhino 5, you used to be a command called pictureframe and one of the options was to embed the bitmap. I have spent the last 20 minutes looking and can see no way of doing that with the new picture command. In fact, I can find no way to embed bitmaps into a rhino file anymore. @brian, is this a correct assessment? Because that would be really frustrating when it comes to file sharing if you can no longer embed the bitmaps.

As for this part, I believe that picture basically just automates those same steps. In both cases, the end result is a surface with a bitmap applied as a texture. So is there a difference? no.

Hello - ‘Picture’ images are treated as regular material textures in V6. They are saved and restored in the same way- that is, if you check ‘Save textures’ in the Save dialog, (default is checked) then they are saved.
