Can't remember how...

I am looking at creating a ceiling hanging in the form of a slab or countertop (whatever is easier)

I cannot recall how to do a polyline subtraction with circles. (it works with rectangles) but basically i want to create a horseshoe shape out of the 3 cirlces drawn as a solid piece.

Help?

I believe the trick was to use a square and then radius the corners.For some reason that worked but a circle didn't.

Chaos-
Draw the circle then select it. There will be a "Convert Curve to Polyline" tool on the Edit toolbar. Make the conversion and you;re good to go.

You can directly use the primitive tools > Cylinder then the solid substraction.
