Extruding an arc shape with a plane as the extrusion path I created this model in AutoCAD and I am looking to recreate this design in blender.

To create the model I created two closed polylines and set there Z's. To draw the arc between the top and bottom plates the UCS can be aligned so that an arc can be drawn in 3D and then extruded along the top polyline to create this part that looks kind of like a lantern.

I am continuing to try to do this in Blender but I have not yet been able to achieve the design. Is this possible to model in Blender?

Thank You!
there could be many ways,  this is one :


add a biziere curve align it to front view
convert it to mesh with Alt+ C 
add a screw modifier 
set the steps to 4 (in the modifier)
