We are thinking about upgrading from 2016 to 2017 C3D.
I'm wondering if anyone is using the new Analyze Gravity Network command in C3D and how well it works compared to exporting our system to SSA.
Thanks, Allen Damron
apples and oranges...
The problem we have with SSA is that any pipe sizes and flowlines that are changed in SSA have to be updated back in civil 3d manually.
If 2017 can analyze pipes inside civil 3d, then we wouldn't have to update them twice, right?

From what I know based on limited research this new feature is for pipe sizing only, kind of like running hydraflow storm sewers within C3D. Pumps, gates, rules etc. and other bells and whistles of SSA not included. I personally think this is a step in the right direction after all these years of separate layout and analysis platforms.

My understanding is this simply does a HEC-22 analysis on the pipes.
As far as updating the pipes in Civil 3D, if everything is set up correctly, you should be able to export a .stm file out of SSA and then import that into the drawing with the network and it will update it.
Defects or Limitations...

Brian,
On the autodesk help site, under About Pipe Network Rules:
http://help.autodesk.com/view/CIV3D/2016/ENU/?guid=GUID-4FBF470E-16EC-497A-82A9-8E84580F3963
It has this note:
Note: It is important to note that rules are not applied to pipes or structures when importing pipe networks from either LandXML or from the Storm Sewers Extension.
I'm wondering how to size pipes....if you don't apply rules, then how do you size pipes with the correct length and slope?

Our office has been looking for a software that does exactly what this says it does. We thought that the SSA would do this, however after flying the guy who claims he was head of the development in. We were very disappointed to learn that we still had to manually type the results back in, and there were a bunch of defects in the software. I quickly tried this new program out, and here is what I think of it:
Hopefully they continue to improve this product, it would be great to have something like this to work.
