My new book on preparing aircraft reference drawings is already available in the web shops. This is the first volume of the new (fourth) edition of the “Virtual Airplane” guide:
Here is the link to this project page. Below you can see a screenshot of two pages from this book:
“Preparations” describes how to create accurate reference drawings from available sources: scale plans, photos, general arrangement diagrams, and even the original factory blueprints. (In the last years documentation of some most popular aircraft became available on the Internet). It discusses typical issues, which you can encounter using these materials.
I suppose that this guide can be also useful, as a book on its own, for all those who work with reference drawings. In particular: the classic modelers and the authors of the scale plans.
