CamBam / FreeCAD 2D/3D MOP question Please help

disregard my first idea as this was done in Vetric, in Cambam first create the semi circle then extrude upwards to the over length you require then follow the instruction to rotate the part.

(To create extrusions along other axis, the shape must first be extruded in Z, then rotate the extruded surface object to the required orientation.
The Extrude operation will first prompt for an Extrusion Height. This will be the Z height of the extruded surface. A positive height will extend toward the positive Z axis (ie toward the viewer when drawing is in the normal orientation with the XY plane parallel to the screen). A negative height will extend the surface along the negative Z axis (ie into the screen).
