Questions about the free resources
- Are the DWG symbol libraries free?
- Yes. Every library on this page is a free download: one ZIP per DWG file, with a preview of every symbol before you download.
- How do I find a symbol quickly?
- Type its name ("gate valve"), a designation ("IPE 200", "DN100", "M8") or a block name into the search box. The Filters button next to it narrows the libraries by industry, purpose, standard and type, and the tabs under the box switch between symbol libraries, templates, sample drawings and LISP commands. The search works inside whatever the filters leave. Symbol names are in English.
- Which standards do the libraries follow?
- ISO, IEC, ISA, IEEE / ANSI, ASME, EN / DIN and AISC are covered, for example IEC 60617, ISA 5.1, ISO 10628-2, ISO 1219-1, ISO 1101 and ISO 14617. Where no standard exists (architecture, HVAC, process equipment, water treatment, metallurgy) the libraries follow common practice of the trade and say so on their page.
- Are the symbols certified copies of the standards?
- No. The symbols are our own drawings after the common forms of those standards, not copies of the standards and not certified for conformance. Check the shapes against your own copy of the standard when a client requires strict compliance.
- What is in a block besides the drawing?
- Every block carries attributes: a visible tag and, hidden, the data a schedule or equipment list needs, such as service, size, rating, manufacturer and model. Plan symbols are drawn at real size in millimetres; schematic symbols at their plotted size.
- Are there AutoCAD LISP commands too?
- Yes. The LISP commands come in six families: text, blocks and attributes, measuring and polylines, layers, clean-up, and export and import with CSV. Each command is one .lsp file, free to download, with its code on the page. Load it with APPLOAD, or use the optional loader that loads a whole folder at startup. They are tested in AutoCAD.
