Finally some more work on Maison de Roulement.
I added the walkway around the bottom of the building. There will also be some way to get down to the ground. Also some detail around the front doors and selected a wheel design. The axles are there, but no connecting bits or protection.
I like the way SketchUp lets you have components, and groups, but I've found myself getting into groups of groups of components, and multiple components rolling up into single components, and I haven't found an easy way to absorb parts of models into other components easily, like I'm used to in 3D Studio MAX. It's probably just my workflow.
