Just one remark - it's true that you don't see the complete picture from the amplitude data alone, like from a single FR curve, but in case of a polar map, you can see how the amplitude response changes spatially and this clearly separates these issues and makes them all quite obvious.
Very nice. The region below ~2 kHz will get affected by placing the waveguide into a finite enclosure (even for the better, maybe) so it doesn't make much sense to try to optimize that further for the IB situation.
You should read it 
At least the paragraph about installation (1.1):
"2. All associated dynamic libraries are included in the baseline release package (4.6.0). These thrid-party libraries won't change very often, if at all, and won't be distribuited again in every future minor update if not necessary."
So please download the baseline package first (4.6.0) and then the latest update (4.6.1 at the moment) over that.
Generally, I think you won't move very far without reading the manual this time - a lot has changed. Definitely you may miss a lot.

Updated Excel Macro Full Auto Loft
I've managed to hack together some more code to make the Excel macro a one click import and loft to curves, surface or filled solid via three buttons.

Mabat can you explain using the example you posted before how
Code:
[b]; Horizontal profile[/b]
;Coverage.Angle = 45
;Term.s = 0.7
;Term.n = 4.0
[b]; Vertical profile[/b]
;Coverage.Angle = 18
;Term.s = 1.08
;Term.n = 2.55Becomes
Code:
[b]; Blended profile[/b]
Coverage.Angle = 45 - 27*sin(p)^2
Term.s = 0.7 + 0.38*sin(p)^2
Term.n = 4.0 - 1.45*sin(p)^2I see the s and n terms from the horizontal on the left side but I can't work out how the right side terms were chosen.
Sure, that's trivial. Whenever you want some parameter to vary around the device, simply choose the values for the horizontal (h) and vertical (v) planes and use this formula. The choice of 'n' is up to you (even numbers give a symmetric shape). This is the most simple example - you can of course combine several sin() and cos() functions like this in one expression.
