We provide training in SketchUp.  CAD is becoming an essential tool for contractors, and SketchUp is becoming an industry standard.  While SketchUp is relatively easy to use, getting accustomed to using its tools, and properly building in it, may take some expert guidance.  Most importantly, SketchUp has a free version that enables a user to do most of what can be done in the pro version.  The free version is very powerful design software, proving that there actually is a “free lunch”.
