What do you like best?
I like the simplicity of it. Creating profiles and finding stats on the storm sewers is easy to do. And I enjoy being able to use it in MIcrostation as well. The project overall is effective at what it is billed at--sizing storm sewers effectively.
What do you dislike?
I wish things like spacing and the library catalog were more in depth. Some things like that in the program are almost 'too' simple. Having a greater library and being able to have a better way to space inlets would be helpful (like in Geopak Drainage where you can place a storm sewer on an alignment and the cross slope/profile slope automatically updates). I also wish it had an option to allow headwalls, as often there are culvert-type end sections connected to a storm sewer. This would help a lot to model the system as a whole. The project also tends to be buggy-much of the linework seems to be corrupted every once in a while, it's not something that makes it impossible to work with, but it does get annoying.
Recommendations to others considering the product
I would recommend understanding basic hydraulic and hydrological concepts before using.
What business problems are you solving with the product? What benefits have you realized?
I'm being able to correctly size storm sewers for closed drainage. Usually this is done on highway projects. I benefited from being able to do calculations via a computer program and not by hand. Generally however, a product such as Stormcad is required to submit calculations, so this is a software option to use.
