Thanks for the input, right now I'm taking photos of fire company's apparatus and modeling them for fun... right now it's just to showcase what I can do with SketchUp. The fire company I belong to uses the models to determine whether or not there is going to be issues entering certain facilities in our first due (turning radius, enough overhead clearance, etc.)
As far as houses, I have modeled a few of them but haven't put them on the web (one might be floating around the gallery), these both were done to help people see what they could do to their house and how it may look with those additions.
I just like to model for fun and want my website to be a fancy "portfolio" of my works, but with a focus on th fire service, as well as home modeling.
