Frame builders: Anyone have tubemiter.exe application?

Fruitbat - I found tube-mitre extremely useful, as you can print out highly accurate cutting templates, showing both inside and outside lines.... I can only assume from your comments that you either have never tried producing multiple mitres at fixed lengths good enough to fillet braze, or you do it so often it has become second nature. I am also guessing you are probably not a software developer. .

Busted... but I can do the maths and the drawing.
I haven't seen tube-mitre, how does it show the inside and outside lines?
I'll download and have a look. I realise that I was being slightly cough facetious in my earlier post
