If a region already exists, this method overwrites the existing region. Use degrees for angles. Parameters: radiusfloatRegion position for the radial coordinate. thetafloatRegion position for the angular coordinate in degrees. region_namestrName of the region. .. deprecated:: 0.6.0add_region_rt will be removed with Motor-CAD 2025R2 (tentative).
