[mapguide-users] Custom Symbols...

Tue Jun 3 17:07:58 EDT 2008

There is not enough information to answer this. Is the rest of the road drawn using the same symbol definition, or is it a separate one (or even a separate layer?). Normally the scale range for visibility is specified for the whole layer, so if you are seeing this with data on the same layer, it could be a bug.
