Rhino stl exporting error

hello, I’m trying to export my model for 3d printing, and when I export to stl file it becomes cracked and rebuild with boxes… How can I fix this? I tried to change the exporting option but it doesn’t. change.

Hello- is your object very far from the World orign?

Yes I thinks so does that matter??

Hello- yes it does - meshing precision is lost at distances very far from the origin - if you move or copy your object to the origin (world, not CPlane) then generate the mesh there, it should clean up.
