I have looked though the discussion groups, even Googled it, and I am having a hard time finding any step by step tutorials or training of any kind on this? all the older posts I have read about people asking for the same thing seemed to have been left unanswered from a year ago +. After all this time, no one has created a step by step anything?
If I am missing soemthing, please let me know, it wouldn't be the 1st time.
Go to Analyzing catchments in Storm and Sanitary analysis (on the help tab). At the bottom you'll find setting up the part matching settings in Autocad and exporting them to Storm and Sanitary analysis.
Study that tutorials. Hope it helps
