I'm a Professional Engineer working with a great team focused on residential structural design. I develop CAD applications to automate the design process. The designers have more time to concentrate on important matters, it's the best way to keep speed and quality high and errors low, and it's quick to understand every calc they run. My current favorite language is C# due to how well it works with Visual Studio. I still maintain code in C++, VBA, and AutoLISP.
