W12 engine block

grabcad

This is based on the Volkswagen W12 engine and is the hardest thing I have ever modeled due to the odd angles and bore offsets. There are over a thousand features and many mistakes and backtracks so I have not included the original Solidworks file in the downloads. I am planning to do the entire engine based on the surprisingly large amount of information on the internet. The internal water passages and oil feeds and drains are largely guesswork. Looking at a real block I am not sure how the cores would be supported so I have probably missed some core plug openings. Dave
