Hi Chris,

I export files for laser cutting also but I find MOI is limited in this - I use RHINO convert to ARC function prior to export. I explode all the curves and then convert any splines or small curves to ARCs. I can set their resolution in the command depending on their final size then I export to DXF using the RHINO R12 NATURAL DXF setting and I always smooth arcs and converted splines that way.

I think a similar tool or script would be required in MOI to do this.

Breaking down to really small polylines sometimes works but some laser cutting software has small limits and if it cant handle it goes wobbly.

Hope it helps.

Alex.
