Topic: Symbols IEC 60617 line width
with pleasure and success I am a new user of QElectroTech
and already a big fan. An her is my second posting/comment:
My topic with this post are the correct symbols in line with IEC 60617.
Up to now I could NOT find ANY free CAD tool, which includes the correct symbols.
The main reason for this is the high cost of PDF and online database access
of such IEC standards. There is only one free PDF from Alsthom about the standard:
But most CAD tools do NOT include the correct symbols. Also KiCad and ProfiCad
with its libraries of IEC 60617 have the wrong dimensions of most parts.
This, because the so called module size and grid of all symbols is defined clearly
in the standard, but wrong in most libraries.
With QET the situation is up to now only a little bit better, but some deviation
does still exist. Especially the line thickness of symbols is currently to my humble
opinion not correct. The line width of 1,00 does not look good and clear
and is not in line with IEC 60617.
It is not easy to follow the IEC 60617 discussions, decisions and standards
if you are not a participating member in standardization bodies,
but I found two example protocols with comments about line width and grid:
With this and the Alsthom pdf, it is possible to create quite good
standardized IEC 60617 symbols with QET. One modifcation for me
are improved or removed connectors of elements and the element
length of 2 or 4 without the length 3. A major modification is also the
increase of line width for all symbols and connections:
Conductor - Appearance Size: "2,00" instead of "1,00"
Element Editor - Appearance - Weight: "Strong" instead of "Normal"
I know about the other (partly old) forum discussions at:
Does it make sense to place/move my contribution to there?
The URL-limitation of "1" for hyperlinks in this forum is a pitty.
So you have to copy/paste/complete my mentioned URLs manually.
Please find attached one small example screenshot:

If required, I can add more examples of my IEC 60617 symbols
or contribute to an official library.
