I recently installed the 7.6 Rhino 7 update. I ended up rolling back to the 7.5 update because the update broke a grasshopper model I am using on a current project.
The problem encountered was in a Pufferfish Scale2Vlume component which failed to recognize a referenced b-rep and failed with an error stating it did not recognize the type of geometry being referenced. I tried to fix the situation by rereferencing the b-rep (a standard polysurface modeled in rhino) . However, this did not fix the problem.
I imagine this will require some updates to the Pufferfish plug-in. However, I am interested in finding out why this occurred and knowing if there is a simple fix on my end that will allow me to install the 7.6 update without losing needed functionality.
As I post this I see other reports of 7.6 update producing a bad objects bug. Am guessing this is related.
