As Big Kev says "I'm Excited!" ..
Aluminium arrives tomorrow, like a Kid at Xmas, Yay!
Sadly they only had 1250 x 2500 sheets, I usually lay everything out on standard 1220 x 2440 sheets, so I will have to suffer a little waste as I'm not going to renest everything again. You would be surprised what a difference 60mm longer and 30mm wider makes to nesting, spreading parts over 30 or so sheets. That also goes for the actual design, you can't make a part that won't fit onto a sheet, or cut up into at least the minimal part sub lots.
But Sketchup will save me, Long Live Sketchy, Sketchy for King!!
