Extruding a curved face along a vector, Please Help!!
(OP)
Hi all,
Please let me know if this can be done because every time I try this I just get a sheet body rather than solid. Here is the description (Unfortunatly I cant upload due to IPR)
Say I have a solid wing shape, all I want to do is offset a square section of the wing surface along a vector by 8mm.
This is what I did, create a datum plane directly above the wing solid. Draw a sketch of the simple square. Do a divide face projecting the square onto the wing surface. Now that I have a separate surface I thought I could just extrude the edges of this surface along a vertical vector by 8mm, but as I said I just get a square 'frame' made up of sheet sufaces.
I have also tried projecting the sketch onto the suface and extuding the projected curves but just get same result.
I know I could just thicken the divided face but this extrudes along 'face normals' not along a vector.
Grateful for any help as deadline due soon!
BTW I dont have the freeform package, just standard NX if that makes a difference.

Cheers,
Rich

That works with divide face, but if I pick the outer edges of the first extrusion, I get a sheet body without the top face. It seems like I run into this alot. Any idea why?
Thanks,
John

Yes that is what I want, unfortunatly I tried it on my part and couldnt get a solid body (solid body checked on extrude).
The only main difference between your part and mine is that mine is curved in more than one plane.
I managed to recreate the unwanted effect I am getting by doing a square on a sphere.
See attached.
Now im thinking that is the limit of my NX package without the 'freeform' add on??

Rich

One thing Si, did you really need the projected curves? I was dividing the face directly with the sketch.
Stars all round!

That should have no effect whatsoever.
And the Face Edge approach works with doubly-curved surface (see attached example).
