Great!
I started an Oerlikon in SketchUp but haven't gotten around to finishing it. I did manage a 73' hull in SketchUp, but it was a complete bastard to do! In fact to do my scratch built Vosper, I modelled the bridge in SketchUp and then laid it out flat in Xara (what an ace vector prog that is) and cut plastic from those drawings.
The results, so far, are here: http://www.frasers-art.com/models/m-index.htm Working in both worlds is really 'educational' You can check out the sections you've drawn, make sure they fair up before getting busy cutting etc. My next problem is going to be finding a rorgamme I can actually afford in my now unemployed state to map, texture and colour what I do!
Have you got your work posted somewhere?
Best,
Fraser
