Tim van Helsdingen has started an excellent Houdini course for beginners on his YouTube channel. We are starting with his section on modeling a table and will follow up with modeling a chair. 

Houdini is a very different 3D application than most because it is node-based software. It takes a conceptual leap in order to get started. If you are brand-new to Houdini you might want to try Tim's intro video to get your head wrapped around how Houdini works. 

You can try Houdini or buy Houdini Indie at the SideFX website. It's a great program that is widely used in professional VFX studios.
