Structural Plans Standard Symbology

[siteturbo]

Hello:

I have been placed in charge of coming up with standard symbology for plan sets within our company. Does anyone have a source of information that has a set format or rules/standards that symbols should like on plans.

Examples:

- what kind of hatching to use
- what should a shear wall look like in plan view
- what should a column symbol look like in plan view
- what does a wall marker refence pointer look like
- what does an anchor/hold down symbol look like.

Thanks.

You need to be familiar with auto cad or whatever program you are using. Its all about line weight/plot style. Obviously you dont want to have the hatch to print solid black. I think you should just look at other companies' plans and copy them a little. You need a good drafter in your team and start a block library for the symbols.

The AIA has a layer standard with weights, etc. You might start there. I use a modified AIA approach. I don't find their layering as comprehensive for structural stuff as I think it should be. They also have layering for Civil, Electrical, Mechanical, etc. Also Harvard University has a rendition of the AIA system that is pretty good. I have two standard line weights that I use and denote them as DikLt and DikStn... the DikStn is based on the ISO standard for the third heaviest weight and the line widths (weights) are diminished by SQRT 2 or 1.4142.

You might want to Google Tri Service A/E/C CADD Standards and obtain a pdf of the entire document. There should be a chapter for drafting symbols.

Another source is the National CAD Standards.

The list you provide appears to be for wood structures. It has been my experience that many of these available standards do not have a decent library of drafting symbols especially for wood structures. I'd go with COEngineer's suggestion of looking at other companies' standards and adopt any good ideas.

If you are lucky enough to have a veteran drafter who started his career before AutoCAD was around, get his opinions on the visual.

Also, I highly recommend checking out Architectural Graphic Standards, which includes a CAD layer list with layer names from the National CAD Standard, as well as symbology. It's definitely more focused on architectural needs rather than structural, but there are many items in common (font, leaders, dimensions, etc), and there are significant structural resources as well.
