I am trying to use a sketch on two planes to loft from a semi-circle shape to essentially a rectangle, but get a very smooth curve (see photo). For the life of me, I can seem to find a way to do this. I will upload a photo of the real thing as well as a screen grab of how I am envisioning using planes to sketch on. I have tried lofting through multiple sketches, but that isn’t working either. Any suggestions would be greatly appreciated!
Hi @mjhillsc
Welcome to the forum.
You have almost done the job yet.
The rectangle has 4 summits so the solution is to draw 4 guides for the loft tool.
The trick is to draw 2 guides, ending on the rounded side of the guitar handle, at some distance from each other, otherwise the loft would fail.
I created 2 construction planes using 3 points each time to define them, and draw the guides using 3 points control mode spline.
To ensure tangency of the guides, I also project some edge or line to the sketches and use the tangent constraint between them and the guides.

And of course you can play with the fillets to get a better transition to the handle.

Well, this hasn’t been easy! But, thanks to @PEC video, and lots of trial and error (heavy on the error side), I got what I was after.
