New vba script: Autocad2EPA-SWMM

Posted by: Skylar In: Stormwater

Though I haven’t seen EPA-SWMM used extensively up here in Ontario, I was required to learn a bit of the program during my undergraduate studies. The first thing I noticed was how tedious it was to have to draw all the subcatchments freehand, and then to enter all the areas, widths, slopes, etc manually. All of this information is already there in AutoCAD. Why not just export it?

Enter this script – Export2EPASWMM.

Currently all it does is draw the subcatchments and enter the areas from autocad. In the future, some additional functionality would not be hard to achieve, if there is a demand for it. Hope some people find it helpful.
