I'm trying to model a curved bump on a flat surface like the image below:

enter image description here

Is there a recommended way to model this kind of shape? Should I add subdivisions to mark the outline of the bump and then have the subdivision modifier somehow create the round shape? I tried doing that but the curve I get is not defined well enough, and ends up looking like the plane has a "swollen" part instead of a well-defined bump like the one in the image...

Thanks in advance

How about using curves?

  1. create a profile shape using Bezier or path enter image description here

  2. create your case contour shape and use the profile curve as taper object: enter image description here

  • $\begingroup$ When you "extrude" the curve with the taper object and use the 2D mode, it will create an airtight mesh wherever your profile curve is place. I think what's relevant is how you draw the control points of the profile curve, not its final position when extruding the contour one. $\endgroup$
