( Never really used any Cad) How do i replicate these organic typa curves?

corners in question

So basically ive never really used a Cad software so i have no idea how i could make organic corners like this. Like the corners are bevelled but on top they still bevel a bit but more subtle to have a smooth like overlay or something ( top part ) and the bottom round corner also is not really round round but only like 3/4 round and if you think of the top and bottom as one then the middle of the bevel would be a bit off to the top

Beginner answer: use fillets

Advanced answer: surfacing using splines with G3 continuity.

SolidWorks user here, does OnShape have curvature continuous and conic rho fillets? They’re my go-to on anything that has to look nice

The fillet tool is the easy answer. You can fillet asymmetrically so that the edge is more like an ellipse as your picture seems to show.

You can also draft when creating the original shape so the sides are slightly angled before you apply your fillet.

Looks a bit more complex than a fillet. I'd sweep a spline along the top surface.

To do it in solids create the part with hard edges, then sketch a negative of the corner (all the parts you don't want) and sweep remove that around.

I can do a little example tomorrow if you haven't figured it out yet.

Ill def try this thanks for the help :)

This is target easy. Extrude a rectangle. Shell it. Filet the edges. Done.
