Ive written a small cad program in a couple of days, it works by taking cubes subdivided once and twisting them around, and you just keep placing cubes. it has a grouping system so if you make a cool piece you can zap it all on at once in a single hit.
thats about it, and ive got pretty pleasing results out of something so simple.
the texturing is homogeonous at this stage and no shadows, cause im on a really old computer and it cant hack anything.
I tried writing an animator not long before this but I just couldnt find the effort to finish it, sometimes I find it sooo hard to get to the keyboard to make these artistic tools, but this one came out quick and easy and I was making the buildings in no time.
