""""""""""however the fuselage shape in question the profile for the top and bottom are different """"""""""""""""""""

Revolve the top shape, then turn on points for the revolve and pull out the bottom shape. (Again, moving a revolves points to far will break the revolve.)

ummm I'm having another senior moment :)

If I'm following you correctly I have revolved the my profile with the Ellipse rail curve. (Rail revolve)

However if I then show points on the profile and move the points the changes are reflected on both top and bottom as expected.
If I show points on the rail and say change position of a point on the rail then the change is reflected along the shape.

With a revolve, you can show points on "The solid"....

Hi Steve, yeah Burr means select the output surface and then turn on the surface control points, not turn on control points for the input curves.

If you want to experiement with that method for deforming the surface, you'll need to either delete the end caps of the revolve or turn off the "Cap ends" option when creating it so that you've got just one surface instead of something with multiple surfaces joined together, and then you'll be able to turn on its surface control points.

Also if you want to try that method, it may work better if you create a regular symmetrical revolve to start with instead of a rail revolve - a regular symmetrical revolve will get converted to a fully squishy surface by a kind of internal surface rebuild if you start pulling some of its control points around.

Wow I didn't know that, thanks guys

I have a play around tomorrow

Is this unique only to revolve?

Hi Steve,

> Is this unique only to revolve?

Well, you can turn on surface control points for any surface object - but not if you've got an object made up of multiple trimmed surfaces that are joined together. When you've got an object like that it will not show control points because it would be too easy to pull them apart and make their joined edge not touching anymore. There's some information on this in the FAQ here:
http://moi3d.com/faq#Q:_Why_does_show_points_work_for_some_objects_but_not_others.3F

But if you get any surface down so that it's just 1 single surface all by itself (either delete other pieces, or use Edit > Separate) and not joined to anything else, then you can turn on surface control points for any individual surface like that.
