GDL Revolve Issues

[Anonymous]

Hello.
I was wondering if anyone had an idea on a problem I was having with the GDL scripting of an object. I am basically trying to create a smashed dome, which I could do using CUTPLANE and SPHERE, but I want to make the object parametric, and am weary of finding an equation which would adapt the cutplane's orientation based on the radius of the sphere (if anyone has an idea on where to look for that, that would also be appreciated).

My issue is that in order to REVOLVE something, it cannot be below the X-Axis, so that means I draw half the arc, and then rotate that a full 360 degrees to obtain the final shape. When I REVOLVE this, it creates a "nipple" at the point of the rotation in the 3D view. I can jack up the RESOL of the object, but the "nipple" still shows at the top of the REVOLVE. I am attaching a picture of what I am taking about (its the darker spot on the top of the dome). Below is the GDL script for the REVOLVE command I am using. Am I missing something? Any hints, tips, advice would be much appreciated.
Thanks in advance.

It is two complex profiles.

You will see how magic wanding the complex profile wall [to a guide circle] with segments instead of "best match" yields short straight segments instead of an artificial curve.

Place the other complex profile at the intersections.
