the paint and decals look good - kind of fresh feeling. The dimensions from the sit bones, plus the reach and then the length to the tops are how specs SHOULD be written up for prospective customers. Why are they not I wonder? But at the same time those, should Thorn make it thus, would make it too long for my body, while the frame size is correct. What a tough job designers have satisfying such a variety of needs and preferences as are out there.
I,m surprised by a few choices you've made. The cranks at 195, would that not be hard to find, and not limit your choices? If the drawing is to scale it seems like the overplayed horror over toe overlap would come revisit Andy - and I think he's likely fed up with that. Also the axel to crown at 370mm is ten mm less than the current Audax. What was attribute you were looking for in that design choice?
I used to draft way back in 82/83 and in 85 was sent for Autocad training (on high end 286's with about 1/1000th the memory of my iPhone). It was way too much fun to be thought of as work. But nowadays the cost of a license is prohibitive and there's not much I'd be inspired to use it for. Perhaps re-doing the kitchen?
I never thought about BikeCad, didn't even know it existed. Is it affordable? That could be a hobby in and of itself, designing the perfect N=1 dream bikes. And much cheaper than buying too!
