Just want to share this workflow for creating a train track for wooden model trains. I've so many times needed to get a specific size of track that is not standard. I end up quite frustrated.
Just found out that I can quickly create a trai track and even complete trains with 123D. Let me walk you through the process.
Please check this model on the 123D Gallery: http://www.123dapp.com/123C-3D-Model/Train-Engine/595304
