There appears to be a bug in "Plane Components". Soon after I drop Plane Components tool on to the canvas it causes my computer to lock up. I am using Rhino 5, GH 7.0055, and Vista.
I think I'm suffering from the same bug in a definition that was working fine yesterday, perhaps the new WIP broke it?
This error is from an Offset component that has a plane component fed into it.
I did close down Rhino, reopened, opened Grasshopper, placed various plane components on the canvas, panned around, tried to delete them and Rhino crashed. I've sent it in through the McNeel error reporter.
I am also having problems with the "Surface Frames" Component in addition to "Plane Components". To test, I opened the drawing in Rhino 4 SR8 to see if these GH components would work, and they worked just fine in the same definition.
Conclusion - it seems that Rhino 5 Sept 29 WIP has issues regarding various GH Plane components.
Yeah, it was a Rhino SDK break. Since Grasshopper uses the SDK that ships with Rhino5 when it's running under Rhino5, any SDK breakage will usually result in a few days of Grasshopper not working on Rhino4 until everything is updated left and right.
