Desing with Multipled curves using the loft

[SCALEMODEL]

You could use loft to make it work but just simple extrude and shape with fillet can do it.

1. Make the curved board.
2. Extrude a rough shape of the lip.
3. Fillet

It’s kinda similar to this process for an AC knob.

Modeling Toyota A/C Knob

I am trying to model an A/C knob from a Toyota Tundra. I’m able to create the basic shape, and extrusions and center grip. However, I am having difficulty creating the smooth curves from the grip into the edge of the round body. The surface curves in 3 dimensions - from an end-view there is a fillet that blends into the side of the knob, and from the side view, the grip curves down into the edge of the knob. Pictures attached of what this looks like. Appreciate any suggestions. Thanks! […
