Node Point Symbology

There was a simple document published alongside IAN 147 some time ago that described the preferred symbols to be used for point items on HADDMS drawings.

Many of the symbols for different point items are the same where they point items fall into a family of similar types of asset. With the publication of the 2nd edition of the HADDMS Data Formats Document in September 2020, there are two new point items (Instrumented Gully and Vortex Separator) and a requirement for one new symbol.

The point symbology is:
