I start with a solid object, when I use the Dir command all normals are pointing outwards. I then explode the object and get a collection of surfaces. For some surfaces the normals are pointing outwards and for other surfaces the normals are pointing inwards. I tired using the Flip commands to flip the inwards normals so they are pointing outwards. I double check that they normals on a surface are pointing outwards with the Dir command. However when I extrude the surface along the normal the direction Rhino Extruders the surface inwards. This is very confusing?
I can manually change the direction but I want to have a script extrude all surfaces automatically along the outwards normal. Is there any way for fix the normal direction for the Extrude command?
