The Sentinel is a futuristic concept car designed by Cristobal Vila, and under his copyright. He invites modelers to try their skill at replicating his designs, as long as his copyright is respected. Pictures of the Sentinel design are featured on Angevine's thread "Concept Car Blueprints" here in Designer's Corner Forum. In this thread will be posted photos of the progress of my efforts at modeling the Sentinel. The original design has too many compound angles for me, so I simplified the car's shape. I am also doing something I have done on a few other models, but is a method that most of you don't use: building a solid model by layering profile shaped pieces of corrugated cardboard to build up the shape.
