Main tubes are defined!

Here we are! Using Schleicher's detailed drawings, I was able to reconstruct most of the main tubes in the fuselage. Some interpretation from the NNZC's photo album is still necessary though.

Initial 2D drawings assembled in 3D.

For this, I first redrew the 2D views from Schleicher, then used Inventor's projection tool to locate intersections in 3D

After linking and projecting the 2D views in 3D.

Quite time consuming (almost 8h), but the next step will be looking into more detailed plans to spot the missing smaller tubes. One essential bit I am missing is the landing gear, and the wing box.

Stay tuned...
