Please see my response on this thread: Rhino to blender not updating mesh but creates a new one - #6 by Jedd
We understand the need to re-implement an Update mode for Blender. We’re currently investigating a solution that is fit for modern Speckle data, and doesn’t have the problems of the original pre-2.16 implementation.
Unfortunately, its a feature that we need to design from the ground up, and as such I can’t give any timeline just yet.
Thank you all for being patient, I’ll keep this thread updated with any progress.
