I am Urban Planner and try to use Arcmap for planning roads.
At first stage, I draw roads by fat lines with type "Cartographic Line Symbol". There are roads, Red lines, and white space between.
But at next stage, roads should have fillet on crossing and red lines - facets. Please help, how it is possible to do this automatically for entire feature class.
PS.: It's ok to convert road lines to polygons at this stage.
