Adding material to a complex curved surface?

Adding material to a complex curved surface?

Adding material to a complex curved surface?

(OP)
I have a part that was made using lofts, the surface is a shallow complex curve. This part was provided to me as a "split" type feature and I do not have the curves that generated the original lofts.

I found that I need a little more material in the middle of the part. Basically what I want to do is leave the edges alone, and bulge the center of the part outward.

The "Features" options modify the base geometry, which I want to leave alone. (I.E. "dome" or "deform").

Perhaps the Boss-Boundary ?? I'm having a lot of trouble getting it to work.

I've attached a jpg of the base part, I'll add a jpg of the problem as well.

Beat to fit, paint to match.

Here's a jpg of the problem I'm having, I need a little more material out in the middle of the part.

My last resort will be to just loft in more material from one end to the other.

RE: Adding material to a complex curved surface?

I would use a convert entities sketch from the top surface and extrude boss up to your desired thickness. Then draw a curve on the right plane to cut away what you don't need - yet still meet the edges of the existing surface. Same for a cut across the front plane. Not sure if this will maintain your curve effectively, but you're needing to change it anyways.
