I need to create a surface model of a stretch of roadway with two roundabouts. And I do not have a Roundabout add-in or extension for InRoads. I found the following post on this in the old discussion groups, saying it can be done and with some quick words of advice.

Can someone expand on how best to proceed with modeling such a roundabout, or direct me to a resource that would help?
Thanks,
Brian
