Hi Dave, I would make these suggestions for a new user (or an 'old' user starting with the new technology):
1.) Take all the relative LEARNserver courses available in the area/software you will be working. You mention templates specifically, so I searched the LEARNserver (learn.bentley.com/.../Public) and found instruction on templates in "Roadway Designer Overview" and in "Advanced Roadway Designer".
2.) Also view existing videos on template in the "Support Solutions" are of the BE Communitites.(communities.bentley.com/.../roadway-designer.aspx)
3.) If you have a question that is not answered in training or a video, search the Road and Site Design forum to see if someone has already asked/answered it.
4.) If the question has not been addressed before on the forum, post your question here on the Road and Site Design forum.
