Kevin Clark did a post earlier this year on “When a Pipe Network Structure isn’t a Pipe Network Structure”. Autodesk Storm and Sanitary Analysis (SSA) uses the STM file format as the mechanism for exporting a Civil 3d pipe networks out for consumption with SSA and the return trip back into Civil 3d – these settings within the command setting become critical. Kevin’s focus was on Civil 3d 2010 and what it did during the export to Hydraflow Storm Sewer. Let us take it one step farther – Autodesk Storm and Sanitary Analysis.
Autodesk Storm and Sanitary Analysis is a Civil 3d 2011 Subscription benefit. It requires that either AutoCAD Civil 3d 2011 or Map 3d 2011 be installed and it is a Stand-alone product that requires you to leave Civil 3d to launch. If you want to launch SSA from Civil 3d, add the SSA program path to the Working Path of your current profile, and add a command macro button on your Ribbon that uses the following command macro;
(startapp “StormSanitary.exe”)
For example; for Windows XP, add the following path;
C:\Program Files\Autodesk\SSA Stand-alone 2011\
The path for Win7 64 is; (SSA is a 32-bit product)
C:\Program Files (x86)\Autodesk\SSA Stand-alone 2011\
Note: This works in Civil 3d 2010 as long as you meet the installation requirements of SSA. SSA can read and write the Hydraflow STM file format to allow you to use 2010. There are other reasons why you may want to push 2011 out to your corporation.
Yes you heard me, static null structure descriptions! One of the most annoying things about null structures when designing a storm system are the description resetting if you make any changes to the connected pipes inverts or within the structure properties. I would always find myself having to go back through each null structure to make sure it did not reset. For the longest time I looked high and low to see if anyone had found a way to fix this or work around this issue. Make the jump to learn my workaround. (more…)

Hi everyone. I would like to say this is my first official post with Civil3d.com. Tonight, I would like to provide you a few tips and tricks for pipe network design. Lets begin by setting the Manning’s coefficient for each of your pipe sizes in the part network list. I provided a list of the three most commonly used storm pipe types below. You can also find this information in most city standard drainage manual. This will come in handy later on in the post. (more…)
Today was the first day of AU sign up in case you missed it. Looks like things are going much smoother than in the past, but I have to imaging much of that is due to the diminished number of folks who will be going to AU without much thought. In the past you could count on the fanboys to jam the switchboard on day one. This year? I’m thinking a lot of us are seriously looking at cost-benefit ratios, and debating how much political capital it’s worth to make the trip. Personally, I don’t think AU can be beat. Three days of hardcore training and ideas for less than most consultants charge for a day in your office.
Anyway, I’m teaching “The Floodplain Truth in Civil 3D,” and I need some new data. I’ve played with the same floodplain data set and HEC-RAS model for a number of years and want something new. If you have a HEC-RAS model you’d be willing to share with me, please drop me a comment below. Obviously, you and your firm will get the much deserved credit for being so generous. Thanks.
