How to Change the Default Sump Depth Value of 2.0 in Civil 3D

Have you noticed that when you create a new storm system in Autodesk Civil 3D 2015 or 2016, the darn sumps are all set to 2.0, even when your rules specify them to be 0.0?  Well here is the fix.

Issue Details:

When drawing Pipes and Structures a 2.0 meters/feet Sump Depth on each Structure is applied. Rules for the Structures with Sump 0.0 meters/feet are set. In the PartBuilder settings are checked but it is not possible to change the calculation of Structure Height there.  So, it appears that the only possibility to solve the issue is changing the Sump Depth to 0.0 meter for each Structure one by one. But there is a better way!

Solution:

  1. Close AutoCAD Civil 3D 2016
  2. Go to this location: C:\ProgramData\Autodesk\C3D 2016\enu
  3. Rename C3DPipeNetworkRules.dll to C3DPipeNetworkRules.dll.OLD
  4. Download C3DPipeNetworkRules.zip from the Autodesk Knowledge Network and unzip it into C:\ProgramData\Autodesk\C3D 2016\enu
  5. Right mouse click on the pasted file and click “Properties”
  6. In the “General” tab at the bottom, unblock the file if prompted
  7. Launch AutoCAD Civil 3D 2016 and open desired drawing file
  8. Apply rules to your pipe network and notice that Sump Depth is now 0.0

This fix also applies to Civil 3D 2015. Same steps, just replace the version year with 2015.

If you would like to include this fix with your AutoCAD Civil 3D 2016 deployment, you can replace the original C3DPipeNetworkRules.dll in your deployment (path is Img\x64\en-US\C3D\C3DPS\AllUsersContent) with the downloaded C3DPipeNetworkRules.dll.
