Can't find a issue based on this anywhere on the web, Whenever iI add an Object or import an SVG object, I am able to extrude it either by EE or by the extrude tool in object data, but I can't do that for a plane ( and just saw for a cube as well ). I get no options for it in the Object Data section nor does Pressing E ExtrudesE Extrude it. What have iI done wrong or not installed? I'm very new to Blender, Thank you!
