![]() ![]() ![]() This will allow those used to different standards to understand the drawing they are looking at.įor example, you might have 10 different parent pushbuttons in a schematic, but the table would only insert 1 or 2 (NO/NC) dumb block/s with the one entry stating that the symbol is indication of a pushbutton. What I believe the post is requesting is a function to add a dumb block of each TYPE of parent symbol used in a project to a table with a short description of what the block shows. ![]() This is an extremely old standard in Australia and was moved away from due to their similarity to the symbol for capacitors. For example, I used to work for a manager who wanted all contacts shown as two parrallel lines for NO and NC had a diagonal line across them for NC. I have come across older Engineers and Managers that are used to one style of symbols and demand everything be drawn using those symbols, however, they are no longer used elsewhere. With the continually evolving standards, symbols can change rapidly at times and what's valid today may not be valid in 10 years time.

I think it's more of a legend of what each symbol means going by what the attached image in the original entry shows.
