A brief look at the CAD packages I am familiar with and some of the work I have done with the tools that each software has to offer...
The software I am most proficient in is Solidworks. Shown here are the projects and interests that I have developed using this CAD package.
Before starting university, I took the time to learn SketchUp to give accuracy to my designs and to provide a sense of proportion which I might miss from my hand drawn sketches.
Blender has given me the tools to rapidly develop and try out various concepts for a recent project I have undertaken. I am still relatively new to the software but I have enjoyed the freedom that it offers, especially when it comes to designing organic shapes.
