I have seen the dragon tutorial and want to put additional CV's like in the video but I can't get them to appear. Is he copying and pasting something??

I guess I would like to know exactly, step-by-step, how to add an isoparm.

I right click on the object and select isoparm from the menu but then when I select the existing isoparm and click away from it where I want another isoparm I get nothing.

Please help.
