Re: Sketching on a curved surface
I am not sure what ridges you want to add, it might be doable without having to sketch on a non-planar surface.
Otherwise, you can use Spline on Surface, see attached file.

Re: Sketching on a curved surface
Why don't you start with an offset plane, and sketch on the plane?

Re: Sketching on a curved surface
Ive done some more digging and Ive managed to do the attached. Ive created a sketch and used the curve pattern option. This worked, but the sketch did not follow the curve and has protruded through the front surface. Any suggestions?

Re: Sketching on a curved surface
Are you using SolidWorks, or a different CAD software? Why don't you post Solidworks files?

Re: Sketching on a curved surface
Uploading the SolidWorks file helped.
You need to use the curve itself as an end condition, see my attached file. I did extrude From: a copy of the fact To: an offset copy of the face
Then when you do a Linear Pattern, as long as "geometric pattern" is NOT checked, it will also pattern from the one face to the other.
You will note that in my attached file, the second fillet won't pattern, sorry, you are going to have to add those back in by hand on each one. note that you can select faces to fillet, which might make it faster.

Re: Sketching on a curved surface
Charles - I'd better do this quietly in case the off-topic police get me. I used a circular pattern rather than the linear one, which I thought a bit more appropriate as the 'lens' is an true circular arc, and you can pattern both fillets.

Re: Sketching on a curved surface
thank you all for your help. I found the circular pattern worked for me. Im not sure why the linear did not. I offset the surface but could not get the pattern to follow the curve.
Thanks again
