Hi Guys, I'm Bobi1 from the Madmechanics forum. I just found this nice forum after reading post at Madmechanics with a link redirecting here.
I'm almost ready with Aventador plans for building body plug with wooden cross sections. This is NOT just some quick projection of sections on the 3d model for a few minutes, like other people trying to sell plans do. I always add lots of additional details, make channels, ribs, holes etc, and my plans are 100% usable. The amount of work is huge. The cross sections I arranged at variable distance in order to provide useful information, such like where the door openings and window openings start and end, to name a few. There are 7 mm deep and 7 mm wide channels to mark the location of all body panel gaps. They are all hand drawn by me as well. It's supposed that builders will cover the wooden/foam plug with up to 2 mm thick layer of hard coat and body filler, so the 7 mm wide gaps on the wooden formers will become 3 mm on the fine finished plug, and 5 mm deep. Perfect for easy release of the moulds. I also add thin lines at each edge (aka "crease line" in the cardesign field) where the degree is too small, so using these guide lines you will know there MUST be an edge in that particular location even though it may look nearly smooth.
For my cross section plans I'm using the 3d model of Lamborghini Aventador extracted by the video game "Forza Motorsport 4" which is low-poly, but is probably the most accurate 3d model of the car and I also improved the shape in some areas to make it even more accurate. Since the 3d model is low-poly Mesh, I had to manually redraw the extracted cross sections using curve approximation technique to get perfectly smooth curves that a 3d Mesh model itself can't.
I make curve approximation and setup the plans to be able for printing on large paper size such like the European standard A0, or similar (suggestions here for American standard?). The plans are in AutoCAD's native DWG file format used by all modern plotters, printers and projectors, and popular CAD software as well.
Current pre-order price is set to 100 USD / 75 EUR, and once the plans are completed* they will cost 200 USD / 150 EUR. Also, people who purchase(d) my Aventador chassis plans will receive the body plug plans for free.
*in about one-two weeks depending on how long the curve approximation will take

Shown below are some examples of plans I made for IKR's Reventon plug 4 years ago, just to show you the details I draw additionally on the cross sections and how the corresponding wooden pieces "lock" together with ease thanks to the additionally designed ribs and channels.
PS: Please, note that there are couple of almost-finished Aventador body plugs made out of foam that some other guys at Madmechanics are currently making, so consider carefully if you want to start building of Aventador plug from scratch, OR just wait a while for some fiberglass kit to be offered on the market. Building plug and moulds by yourself is not recommended unless you are experienced and know you can handle this type of work.
