I am trying to use the extrusion command on a generic family I've made the square object and clicked the finish button, but now there is no option under the Mode tab to modify the extrusion. I'm about to pull my hair out right now because I need to create a custom roof and using the "generic model roof based" as a starting point I can't even get the extrusion command to close as there is no cancel or finish buttons to click. WTF!?!?!
