Rhino 6 Grasshopper Geometry Pipline Error / Bug

Hello all,

I have encountered a strange bug in Rhino 6 (latest release) in Grasshopper. When I open the attached file the Geometry Pipiline in GRasshopper will not work. Also when I refference the curves to a curve parameter and than change the curve it will not update.

Any ideas?

For sublayers, you need to include the name of the parent layer(s) - in this case like this:

PPM::Section

I didn’t understand the second issue…
