Hello folks,
  Is there a way to round the edges of a prism... kind of
Superellipsoid-like? If so, let me know.
  Thanx to all,
   tgl

I've had some success using a sphere_sweep built on the same spline as 
the prism with a radius of the size I want the rounded edge.  Use a 
union or merge of two scaled prisms with the sphere_sweep.

Doesn't seem to work consistently for all spline types though, you may 
have to tweak it some. Depends on the type and complexity of the spline.

Have a look at this thread to see a couple of ways of making rounded prisms.

  Brilliant work!
 (The following question has been forwarded by a member of
the Society of the Coding Inept.)   When using the "Generalized Rounded
Prism" macro, how is the radius of the edge controlled?
  Thanx again,

Thanks, tgl!

//Generalized Rounded Prism
#macro RPrism(Vtx, Sides, SH, SR)

Vtx is the 2D vertex list
Sides is the number of sides
SH is the side height
SR is the side rounding

So SR controls the radius of the edge. Makes sure SR is less than SH.

Have fun!

- And if one want to go "3D", then that is possible too:
