I have just started using Povray and  Moray. What fun!

I have a couple of questions and one minor problem.

I had to construct simple triangular slab. I was surprised to see no
direct way of doing this.  I used CSG difference and chopped corners off
a square. I could have used spline. Is there any advantage either way?
Assuming I'm not bevelling etc.

Another model required a helix (coil). I could not figure out a way to
do this in Moray. I used a separate prog (helixr) and imported. Did I
miss something?

Finally, I used rounded cube plug to form plinth. The 3D view (in GL)
makes it too thick and my object sink up to their ankles. All the other
views are correct and render is fine.

i would have used a height field, that way you can bevel by smoothing the
edges of the hf file, but tahts just me :)

nope, there is a moray plugin for splin objects, but the seperate app you
mention does the job fine (what i use for such things anyhow)

Well, you could have just done a translational or tapered spline object. 
These can create arbitrary shapes like you need.

The OpenGL has problems every now and again, I've found.  I'm not surprised
that the rounded cube goes a little weird.  Maybe Lutz will get around to
finxing it soon?
