Fastest way to create a spherical look on the end of this using zmodeler (where I’ve highlighted with temporary polygroups) I’m trying to make it as if I attached a half sphere to it! What’s the fastest way to do this? Go!!!

Which way is it supposed to be oriented? 
Trying to make a shape similar to the red lamp on the right. So, oriented in the normal direction facing outward from the temporary polygroup:
Um, click on the central point and drag out? Maybe divide up the poly’s on the face first, using triangles only?
