My initial thought is that steps
resolution should depend on the scale perhaps.
20cm in plan or elevation will be a bit
pointless at 1:500 or 1:1:1000 – would look like a fuzzy line.
Standard symbolized rise:tread of 2mm:3mm (or
whatever) might be better.
Similar might apply to handrail elevations.
The idea that some symbolizations might be
different in plan/elevation/none projections is intriguing. I don’t
think we have that yet (?), but it seems like a good idea for some types of
symbol.
Edges, Borders
Personally I’d just go for a general
line edge and drop the rock edge. Or, given the current symbol set,
stick with ‘line rock edge’. Having said that I find I often
want variants of general edges, lines or borders for all sorts of thing.
Maybe a line edge –scale [xs s m l xl] is a possibility and use the scale
to scale line weight and symbolization size? Same would be good for line
border. I like the current invisible, visible, presumed, temporary
subtypes but I do find I use them for situations other than what their name
suggests.
On a related topic…
Attached are some text changes I was just
proposing to our local group for the ‘english translation’ of
legend text. Some are slightly clumsy in the phrasing and one spelling mistake.
They won’t necessarily all be appropriate for the global English audience,
but I expect at least some are.
Also as in this picture below,

there is some untidiness and discrepancy
in the symbol text size in the legend. It could however be a function of
changes I have made at this end.
