The PZL M-28 Sky Truck Aircraft Solid Assembly Model consists of 222 solid part primitives collected into 9 sub assembly modules.
All of my models are developed specifically for use by conceptual designers, experimenters, educators, students and hobbyists.
The models are constructed from scratch employing scaling of publicly released simple 3 view drawings and experienced based assumptions. Although general representation is very good - detail accuracy and accountability can be compromised by this approach.
I have successfully applied this tactic in classrooms wherein the models serve as points of departure for a large variety of student projects involving part redesign, concept alteration and new concept evolution.
