Change Extrusion Method Back To NURBS

I’ve run into a strange glitch where Rhino’s extrusion method is no longer NURBS. Instead, all curve extrusions are generating Meshes. Where can I reset this so Rhino creates NURBS as it should be doing by default? Thanks.

Hello - Rhino never makes meshes from the ExtrudeCrv command - by default is makes extrusion objects

You can turn this off and get only surfaces/polysurfaces by using the UseExtrusions command.
