CAD Inter-/ Extrapolation Additional Informations

As the informations content in the blueprints is rather low for a -not structure identical- built I had to interpolate some additional information ...
the "mill" is intersected with the spacers arrangement and so gives a cloud of additional points for stringer allocation.

Alright Harpye, your on! I'm already learning, looks like I'm gonna do a Typhoon as well, but mine is gonna be a bubble top version. Should I start a new thread?

A new thread would be nice!
After all participants have opened a thread for each I will gather them all together by links into a lead thread which will be closed after entry to everyones way to find all threads is the same...

Good luck on yours!!!
