Issue with exporting mesh from Rhino

Issue with exporting mesh from Rhino
There is an issue while exporting model from Rhino to .STL and .OBJ.
It just turns in a damaged mesh in Cura and even in Rhino when importing it back.

Does anyone have the same situation? Would be glad to get some tips about this.
Many thanks,
Alina

From the image it looks like your object might be very far from the origin… That will make bad meshes. If so, move it closer to the origin and re-export.

Hi,
thanks a lot, that was really helpful.
I’m curious why it happens? If you could explain that will be amazing!
Many thanks,

This has to do with how digital computers deal with numbers - floating point math. Meshes in Rhino are created using single-precision numbers and when an object is very far from the origin there is enough rounding error in those single-precision calculations to make a jagged looking mesh. This is a pretty common issue posted here, which is why I recognized it just from your image.
