Well... It's a very old project but it deserved to be presented on this blog. Two years ago, I decided to model an Optima from scratch in glorious 3D.
I began crawling thru the web looking for material. I didn't own any optima in 2005, so I modeled everything from manual's scans and pics found on Ebay... and from my own rememberings (I had a Javelin when I was 15).
The only app I was confident with was SketchUp v4 (by AtLast Software at that time but now property of Google). So I modelled everything with that pretty straight-forward yet powerful 3D soft.
