One of my learning objectives for this semester was to become familiar with AutoCAD overlay.

Vector file - the drawing obtained using AutoCAD software in which you can draw lines, circles, arcs, etc.

At work we mainly translate electrical diagrams, water pump designs, and layouts of piping and wiring.
