CAD to rotate a two-dimensional image around a Y axis?

One of the things I have wanted to do is recreate a dish I made in a pottery class: roughly what would be obtained by rotating the attached image around the Y-axis. It's a bowl of sorts with a smaller raised bowl in the center.

What would be the recommended way to do this? Is it straightforwardly doable in TinkerCad? Should I be using another tool if I want (in this case) to create a solid by rotating something around its center?

This may not be the best beginner project, but I thought I'd ask.

If you can get the shape as a SVG or DXF file, then OpenSCAD can construct the 3D shape for you, potentially as simply as rotate_extrude() import("shape.svg");

If you would provide a DXF file, I could create a STEP or STL file for you.

My take on The Bowl, made in fusion 360.
I have no idea about any other cadprogram

85mm in dia, resize it to suitable size

In FreeCAD you can 'revolve' a face around an axis to make a solid of that profile.

Also known as lathe, or lofting, this can be done in several programs although the name of the function may change the process is fairly straight forward, to rotate a spline around an axis or another splines axis, it can also be termed as Nurms or Nurbs, depending on the software.

I think it can be done in FreeCad.  I was not very particular on the splines but you get the idea. Click on the image to see it all.

I've done a number of drafts in FreeCAD where I started with a good high-contrast photo, converted to .svg, and then promoted to a face and extruded to a solid.  I have not had the need to do a revolve to a solid, but it appears to be similar and I'm confident that I could do it.
