I create a sketch then attempt to extrude the sketch - image then disappears immediately - there a setting some where I think but up to now cannot find it - anyone got any suggestions?
Can you share the file, or share a screen shot of what exactly is going on? There are nuances to behavior that we need to see.
As Dan indicated, it's difficult to help without more information. What exactly disappeared, and when? Did the sketch disappear as soon as you closed it, did the extrude disappear after closing that feature, or something else?
For assistance with Dan and Glenn's suggestion, see: How can I attach a file to a forum post?
