Hi, i'm having trouble with the instant road plugin (free) and sketchup7.1 (free).
Whatever i'm trying i get "ERROR: No group selected". i have exploded the ground surface as stated and the centerline is in a group. With both selected i activate the plugin and get the error. any tips ? The instant roof plugin is working fine btw.That error message is generated when the script doesn't find any group in the selection set. Are you sure that the centerline is enclosed in a group and not a component?
Hm, Yes you are right, i used a component. 
Because the shortkey to create a component is "g" which lead me to assume it was a group. my mistake.
Thanks for your reply btw.
