In order to keep the grid fixed, the page size is set to A4 size and should not be changed, as doing so will move the grid and mess with the formatting of the symbols. Anchors for graphics anchors such as circle centers.Designators for the designators (R1, C3, U3 etc).Values for values (in the case of passives, their nominal values like 10k Ohm or 100nF).Line thickess was kept as 1mm throughout symbols.In order for the images to be compatible throughout all systems, the font used is sans-serif which is an open-source adaptation of Helvetica.Points use a 1mm grid with thicker lines at every 1cm.In order to ensure scalability and reproductibility, certain aspects are enforced and uniformized throughout the symbols: Since the standard does not indicate grid or sizes, some liberties were taken to better reflect the symbols in the standard to digital form.

This symbol library follows the IEEE/ANSI standard 315-1975 for its references as to how to draw the symbols. Software documentation, specially embedded firmware.As such, the library can be used whenever detailed circuit schematic characteristics are needed: The initial versions were used in the Acheron project documentation, aka Acheron Docs. This library was first intended for the writing of circuit and hardware design documentation, which needs thorough and detailed drawing of the schematics involved. Status: actively maintained, under construction but usable.The tool used to draw and edit them is Inkscape, a free and open-source vector editor.

The main purpose of these symbols are to be freely available in a vectorized format so they can be modified, adapted, scaled and documented in any way needed. The original source is from Inkscape and all sources are developed in Inkscape SVG format which should be natively supported by most vector editors like Illustrator, CorelDRAW et cetera. Electrical Template Symbol Library IntroductionĮlectrical Templates is a symbol library used to make good-looking and uniformized electrical circuit schematics in a vectorized software.
