Woodworking in 3D

I am a retired mechanical designer who use to design electric motors using SolidWorks. Now I am using SolidWorks to design woodworking projects, which is my hobby. I have a few questions.

Is there a community of woodworkers who use SolidWorks Maker?

Are there templates for various woodworking joinery for cabinets and such?

I'd love to learn how to design a room full of furniture so I could do a walk through. 

Thanks
