Spiraling Extrusion
I need to make a spiraling extrusion of 180 degrees or less. I tried using a reference plane on the concave curve and sketched a triangle on the reference plane, extruded it 2.80mm (connected the outer circle with the inner circle). I'm able to get close. With a height of 3mm I'm able to get it to work without an error up to 2.88mm. At 2.89mm and I get an error "Unable to create this feature because it would result in zero-thickness geometry." I'm not sure if the wrap command is the best feature to use for what I'm trying to achieve. Perhaps the Swept Boss or Lofted Base may be a better choice? Please see the attached pictures to understand better what I'm talking about.

I was able to complete my objective successfully thanks to you! I had to do it slightly different though as I didn't find an option to knit the surfaces. After I successfully made the loft I then had to make a sketch underneath the loft (the other half of the circle) and then simple extrude it up to the surface. This is exactly what I was trying to achieve.
Make a spiral 180 degrees as a surface.Then extrude half a circle as TO SURFACE.
