CADXChange electrical symbol library, IEC 60617 style (DWG)
===========================================================

51 symbols as AutoCAD blocks, drawn in millimetres at 1:1. Plain DWG (AutoCAD 2018 format), no add-in needed.
The symbols are drawn after the common IEC 60617 forms. They are not copied from the IEC database and the library is not certified
against the standard. Check your company or client standard before you rely on a shape.

Conventions
- One block per symbol, named IEC_<NAME>, all geometry on layer SYMBOL.
- Terminals sit on a 5 mm grid (turn on GRIDSNAP 5 and snap to the ends of the terminal lines).
- The insertion point is terminal 1: the left terminal of horizontal symbols, the top terminal of vertical ones.
- Every block has a visible TAG attribute and the key parameter (for example the resistance or the rated current) next to the symbol.
  The other attributes (ratings, MANUFACTURER, PART_NO ...) are invisible and only show in the attribute editor (EATTEDIT, or
  double-click the block) and in exports. DESC holds the name of the symbol.
- Model space holds a catalog of all symbols (cells of 60 x 45 mm); the CATALOG layout shows it at 1:1 on an A2 sheet.
- To count the symbols or list their attributes in many drawings, export the blocks to Excel with BlockSync: https://cadxchange.net/blocksync
