Problem in Rotating Surfaces in Gmsh
 

Dear All,

I am a new user in Gmsh. I am trying to rotate few surfaces together against an axis and not getting the type of extrusion I am looking for. I have attached an screenshot and the Gmsh script file (in txt format though).

I am trying to rotate all the surfaces within rectangular space ABCD and my axis/line of rotation is AD. The desired outcome is shown in the right-bottom corner (typical slice of a cheese cake). But, what I am getting is different (see the portion with question mark).

Any suggestions will be greatly appreciated.

bests, fahd
