CAD Symbols — Notation, Signage and North Arrows

Six files of drawing notation and signage. A legend sheet of 972 entities sets 256 pieces of text against symbols for plumbing, drainage and electrical work spread over eleven layers. A north arrow file holds 1,630 entities on 39 layers, with the north symbol drawn several different ways. Safety signage follows: emergency exit signs on 22 layers numbered EV01 to EV14, a workplace hazard sheet with 83 hatches in the familiar black and yellow, a set of prohibition signs, and 38 sport pictogram inserts.

Notation symbols belong in the drawing frame and the legend, plotted at the same printed size whatever the plan scale, so place them in paper space or size them against your text height rather than the model. Signage plans are drawn at 1:100 with the pictograms enlarged to stay readable. The exit and hazard signs rely on hatch fills in the colours the standards expect, so keep those hatches on a layer of their own, where a global scale change cannot wipe the fill out.

Questions

What is on the legend sheet?

Symbols for plumbing, drainage, electrical and fire services with their descriptions, split across eleven layers so you can keep only the trade you need.

Do the safety signs follow a standard?

They use the familiar shapes and colours: red circles for prohibition, green for escape routes, black on yellow for hazards. Check them against the code your drawing is issued under.

How should I scale a north arrow?

Size it against your title block and text height rather than the model, so it plots the same on every sheet in the set.
