ProjectSketch is a free SketchUp add-on for the selection and placement of Office Furniture in SketchUp drawings.
ProjectSketch is free and includes a generic furniture library with hundreds of 3D contract furniture components. (A multi-manufacturer data subscription that includes thousands of Components from dozens of major manufacturers is also available.)
If you are interested in Office Furniture, (or just want to help out), I would love to have you take a look at ProjectSketch. Even if you don't use office furniture, you may find the Componenent Placement Wizard handy. This wizard, also contained in RpTools, lets you select any SketchUp component from a Windows Explorer like interface, and use the arrow keys to rotate the component while placing it (very handy for furniture)
