GH not reading surfaces correctly

Hi everyone.

Really simple, my geometries are not being associated correctly to GH. The GH geometry does not match the Rhino geometry, even very primitive ones. In addition, when I orbit my 3D views, GH seems to be rebuilding meshed whenever the viewport changes.

This happened all of a sudden.

Your shapes are really really far away from the origin aren’t they?

This looks like meshing artefacts, which is what happens when numbers get very big. The actual nurbs curves and surfaces are stored using double-precision numbers and so won’t suffer from these rounding errors until much later, but meshes are stored as single-precision numbers (half the size in memory).

Thank you David, that’s exactly it. I moved everything closer to the origin
