as a noob i have to say that my hand was up. i check angles, otherwise the design process means very little-especially when one is trying to learn what tweak means what (in reality-not reviews legend).
there's a bit of tolerance yo.

It is not commercially available, which is a shame.
It was written by a chap who worked at the A.I.S some years ago.
I was involved with some tweaks to the program in efforts to bring it to market
but the owner of the program has done nothing with it for 5years , SIGH!
Every one now uses the other BikeCAD which I learn has some connection many years ago with the program I have.

nope. no need to draw them out - just make them. you could always scale it down.........OK - serious question for you noobies - how do you know if you angles on your finished product match you design? ever check? huh? ..........not so many hands going up in the class room now - Garro.
I guess you don't need to but drawing in the CS helps me with dialing in that BB drop. Otherwise, both head and seat angles would be off if my CS-ST angle deviated much from the drawing which I check against the frame after each joint is finished. My seat angle looks pretty dead on in this photo:

Henry, In regards to not bothering to draw in chainstays, once one has extrapolated the bb to steering axis number and the bottom of the head tube number from the drawing, the chainstay length and BB drop are directly set on the HJ fixture. I think maybe is a case of Fillet vs. lugs, if I was using lugs I would totally make a full drawing like you have there.
I can do trigonometry all day, and instead I use bikecad. Absent spending $300 on BikeCad, there are a few alternatives. Kinda wish the bikeCad upgrade would come out.
yes, the spreadsheet is out there. Check this post from the framebuilder's list.
Update, I'm liking rattlecad, especially because it uses a standard XML file to store its data. This allows me to edit the numbers like tt length directly, which is a lot faster; the rattlecad interface can be a little funky to figure out how to edit what dimension.

Yeah, having a jig would help but I get by with my trig and $25 worth of angle iron and clamps.

put the rest of the tubes on and check back..... - Garro.
