What every plan set gets before it reaches you
An engineer reviews each set. The software has already checked the rest.
An electrical design canvas that checks as you draw
Symbols snap together, and the one-line and three-line stay matched. The 120% busbar rule, conductor tags and wire sizes are checked on the canvas, so errors show up before the plan checker finds them. Describe a change in plain words, review it in red, then approve.
Reviewer comments make the next set better
Corrections from a plan reviewer are recorded against that jurisdiction with the code article and sheet. Your next set there is checked against them before you submit.
Also in every set
