thanks! i'll give it a try and try to remember to report back.
i have traditionally changed isolated parking stripes in autocad, convert to plines, give them a width, them wblock out for import to sketchup which works well enough. trying to avoid cadwork thought and streamline the process in SU.
ALSO,
Vali Architects, "Instant Road NUI" has great many features including "Striping" which will take SU lines, convert them to faces and drape them onto a surface mesh.
thanks,
bob
