We have a set of users who have an old project using files created in v6.
Their assertion is that opening these files in v7 - we’re slowly migrating to v8 - “doesn’t work”. I am seeking clarification of what that actually means but, meanwhile, does anyone have a matrix of compatibility for the different versions? Should v7 be able to open, manipulate, edit and then save to v6 format?
There is also a very nice Rhino file conversion program posted in this topic. You can use it to convert Rhino 8 files as Rhino 6 files, for example. Make sure to download the latest version.
