Basiswissen Dachfläche Ausmittlung
Base Knowledge of Roof Surface Design/Geometry

The book is a collection of revised articles from the journal 'The Carpenter'. The contributions provide foundations and numerous exercises of varying difficulty. The task solutions are presented step by step, so that the practitioner is a quick introduction to the subject and then be able to expand and deepen his knowledge.

The flatness of the Dashfläche can not be clearly ascertained in these views.


This where the Google translation this suck. Are they talking about the Real Roof Surface or how flat the surface of the prism is? The entire book is drawings on the development of the real roof surface, so hopefully it's the Google translation of the German to English.

In the book Basiswissen Dachausmittlung they show how to develop the roof surface of a prism. The method they use is similar to the Mowat brothers tangent handrailing method of developing the surface of the prism. Their drawings are confusing, but it's probably because I can't read German.

In this drawing I unfolded the prism to develop the pitch of plank. Then developed the surface of the prism using their method.

Here's the way you develop the surface of the prism using the tangent handrailing method. Unfold the prism then use arc's to establish the points of the prism surface.
