Many thanks Arie, fixed it :)

Hi Eddie! Grasshopper uses the units from Rhino. I think your Model Units is set to Millimeters in Rhino, which explains the 10000000 mm2, which is the same as 10m2. In the Rhino menu bar go to Tools > Options and then under Units, check that the Model Units is set to Meters instead of Millimeters. It will ask you to scale your model, hit YES. This should do the trick. See attached image for clarity I hope this helped good luck! Arie
