On a serious note, a lot of residential-based architecture is "plug n chug" for its
structural requirements from the Uniform Building Code.
Granted, this doesn't address harder stuff or many renovation based changes in structure, but that's
also where it makes sense to focus the expert's time/attention on the important/unusual stuff that
can't be found on a look-up table, such as how many ganged 2x10s are needed to replace a doubled
2x12 for a span.
And an architect for a bathroom or kitchen? Cabinet boxes aren't hard IMO...Thats why Home Depot
will offer to do it. Maybe if there's something unusual about the space such that you want an old
hand who knows more tricks.
In any case, if the software's basically just for design, then the dialog with the architect becomes
easier for him too: they know exactly what is wanted and what he is to work within to make it work.
