How do you show them? Do you show them schematically or accurately?
Depending on the situation, we typically use the pictoral installation details Simpson provides on their Strongtie.com site, or the cd you can get mailed to you with their catalog.
That's mostly for wood connectors, concrete anchors, straps, and other such connectors. For shear walls, we'll have a roughly-scaled elevation of the shear wall with connection types called out, and a table noting what hardware to use with connections, and a separate sheet for connection details, where we have a slew of the Simpson details shown pictorally with minimal annotation.
Not sure what you mean specifically, but that's one example.
For times when we have Simpson hardware in our structural foundation drawings, we'll typically have a detail with the orthographic hardware drawn in, in one of our typical sections/details with the other foundation details, but typically they're things like sill plate anchors, or tie-down straps that can be included with the typical foundation details in a similar way as I described the shear wall details.
