SewerCAD User Data Extensions

Mohd Azzam
Offline

I am trying to use user data extension in SewerCAD  (under Conduit) and creating the following formula;

(DownStream pipe Invert - Manhole Invert)

But unfortunately I was not able to find Manhole Invert there in the conduit; I know it is under Manhole but I am preparing output and need it to be there.

Regards......MO.

    Hello,

    There is no direct way of doing this. This is because the data for different elements is stored in different parts of the database. Therefore, only properties from the same element can be used to make a formula User Data Extension.

    There are a couple of things you can try. First, it is possible to make your own FlexTable for the project. One of the options to do this is to make a Two-Row FlexTable, which allows for limited information from the nodes to be included in a conduit-style FlexTable. This includes the invert for the upstream and downstream nodes. If you create a table with the inverts for the upstream and downstream nodes as well as the invert elevation for the conduit, this can show where these may differ. However, you will not be able to make the User Data Extension.

    Another option can work for manholes in the model. There are results fields for manholes in SewerCAD is called "Elevation (Invert in 1)," "Elevation (Invert in 2)," etc. These show the invert elevations for the first incoming conduit, the second incoming conduit, etc. While these are typically used to show the invert elevations for cases where more than one conduit drains to a single manhole, you may be able to use this to help with your UDX. You can use the different between the "Elevation (Invert in 1)" and "Elevation (Invert)" for the manhole element to show the different between the two. The only place this will not work is upstream-most manhole in a gravity subnetwork.

    I do not think that will target what we need to present in the pipe FlexTable using User Data Extension. The best is to have the manhole invert in the conduit database and in that way I can calculate the back drop, or Bentley to enhance the FlexTable to report the back drop values.

    Hello MO,

    I have file an enhancement to see if it will be possible to add something like this to a future version of the program. The reference number for this is 220396. If this is implemented, it will be in a future release of the product.

    For now, one of the other methods above are available. You could also export or copy data to Excel and import or paste the data back into a User Data Extension.

    Hello,

    The following link has information similar to the second option I suggested above: communities.bentley.com/.../20225.reporting-drop-depth-of-a-manhole-or-catchbasin

    This appears to give you the results you are looking for, though it will need to be reported in the manhole FlexTable, as these are manhole properties.

    Thanks,
    Scott
