Extrude curve does not make lightweight extrusion

Rhino Rhino for Windows
4

Hi Rachel, normally this setting should stick between sessions, so if you set i once from the commandline it always should use extrusions if you extrude. Please try this:

  1. Set _UseExtrusions to Extrusion from the commandline
  2. Extrude a rectangle
  3. Select the result and run _Properties and click on the Details button
  4. It should list that the object is an extrusion
  5. Close Rhino, reopen it and do step 1-4 again

Is the result an extrusion or polysurface ?

Sometimes Rhino cannot create an extrusion, but with a rectangle it should always work. Maybe you should post the curves when it does not work with a specific curve.
