Google recently purchased the popular 3D modelling program, SketchUp, and has released a
FREE version to the public. I've written up a
tutorial article for the frontpage on where to download it, and I walk you through the basics in a guide covering the first tutorial that comes bundled, step by step. This is the first in a series I will be doing for TBCS - the next will be going through the next two tutorials, then going over creating a few basic and advanced shapes from scratch and importing textures and models, then we'll be moving on to actually modelling a computer case to plan for a case mod.
Please take a look, this is the second article I've written for the front page and appreciate any constructive criticism you could provide. Thanks!
