Ok, this looks like a really useful feature we should have done long
ago. Yes someone please log an enhancement request for this in Project
Tracker and include a reference to these e-mails for the use cases.
Thanks,
Bob

I've been wanting this in MG for some time.
Another example: say I have a polygon layer (parcels, zoning, habitats)
and the boundary of the polygon should be interpreted as imprecise -
say, the actual line could be within 10 feet on either side. I would
want this line to have a 20-foot width, that is defined in ground/map
units.
This avoids the common issue of having users attribute false precision
to boundary locations as they zoom in. It's a big issue in map use.

Yes, for lines and borders. Should I put in an enhancement request? :)
Lines are most important. In many cases I want them to show up as a
fixed width. Two examples:
- At large scales, I want road centrelines to show up at the their
physical width, as defined in the database. I don't have a polygonal
roads coverage; this allows me to shade the roads.
- I want to be able to do the same with utility pipes.
I can work around this by pre-processing the lines into polygons (using
FME), but it would be much nicer if I could just define a map-units line
width in the application.

Jason,
Do you mean mapping space line width? In that case the answer would be
no. However, this is a feature that can easily be added.

Is there any way to define lines in map space instead of device space?
This is going to be a considerable problem for me if not...
