Three-Point Arc Tool
Use the Sheet Metal Three-Point Arc tool to sketch an arc when you know its chord angle and the location of its start and end points.
Lines, splines, and arcs are extruded to the thickness of a sheet metal wall when they form a closed profile. You can change the default wall thickness in the sheet metal properties.
In addition, you can choose the Profile option to create a wall that is perpendicular to the sketch plane as you sketch.
