What it does
AutoCAD-style drawing
Command line, object snaps, ortho, polar tracking, grips, and window, crossing and lasso selection.
Projects of sheets
ANSI sheets with a grid of zones (6-D1 references) and an editable title block.
Your own library
JIC/NFPA schematic symbols, panel footprints and parts. Three-phase power symbols, terminal strips and PLC I/O points.
Wires and wire numbers
Wires stay attached to symbols. Wire numbers (6001) number themselves, with distribution blocks (6001A) and off-sheet connectors.
Tags and cross-references
Device tags by page number (CR601), contacts linked to their coil, and cross-references that update themselves.
Files
DXF in and out, DWG in (AutoCAD R13 to 2018), PDF out.
