Harritan sketchers use CAD (Computer Aided Design) to detail every aspect of our fabrication. Whether it is piping isometrics, sheet metal flat pattern layout or structural steel detailing, every dimension is checked and re-checked prior to actual fabrication. We are currently using the latest version of Autocad and have the capabilities to plot or print 8-1/2" X 11" to 36" X 42" drawings.
