Panel in aircraft fuselage

Hi, all!

I have modelled an aircraft’s fuselage (let’s assume it is a cylinder). Now I want to cut a groove in it to show the limits of a removable panel. I suppose I could extrude a circle along a curve drawn on the fuselage’s surface, but what would be the next step?

Thanks in advance,

Thierry

The simplest way to me seems to be to select the vertices intended to be the panel, then press the P key and click separate. The vertices selected will then become a separate object, no longer editable in edit mode. When you return to object mode you will be able to manipulate, animate, texture, or edit the newly created object independently.

Try if you can adapt this technique:
