A typcial line with 1/2 of a leader arrow each end, on opposite sides. Bundle and # of pieces not included.

Another one is a circle with lines inside parallel to the direction of the flutes. The lines are intended to read as the deck flutes. Typically this symbol has a letter or number that is tied back to a deck schedule which defines deck style, deck gage, and spacing of deck attachments. Bundle information or number of pieces would not be shown on the structural drawings. You would only see this information on deck shop drawings. The question is not clear as to the context where the deck symbol would be used. Typically an engineer who is calling out deck material is familiar with one of the common symbols. I cannot imagine such a symbol being shown on the architectural drawings.

I should have directed you to the National CAD Standards for their module on graphics and symbols.

I would doubt that many even have a copy. From what I gather the structural engineering community has not been involved in the National CAD Standards process. The one convention from the National CAD standards that has been adopted is the drawing layer naming convention whereby structural layers start with an "S" Margaret G.

Stroud Pence Assoc. My husband works for them.

Even though the structural design community has provided valuable input into the development of the NCS since the original release of NCS v1.0 in 1999 we still need more help from this user group. I encourage readers to join the NCS Project Committee at www.nationalcadstandard.org and get behind the effort (there is no charge, other than owning a copy of NCS v4.0). If structural designers need a symbol that is not in the current version, a graphic of the symbol can be submitted for adoption and we can include it quite easily in NCS v5.0. FYI: Many are also unaware that printed output complying with NCS formats is a requirement for minimum BIM according to the National BIM Standard. Hope this helps!

One impediment to more people becoming familiar with the NCS is the Cost. It apparently costs $410 for a single copy. While individual firms are members it appears that none of the structural engineering organizations have officially participated in the effort. Looking on the forums I had the impression that CAD layer naming is very much a work in progress. While there are undoubtedly some structural firms using the NCS, my sense is that in Northern California that there has not been wide acceptance. It would be interesting if there were a survey of the level of compliance of NCS firms. If the standard is adopted in one office is it also used in all other offices?
