Hello,
I am working on design sewerage system for a zone, about 22 km of networks are collected with one station.
when i choose the design engine it the file gives me error that the invert level is higher that the ground level.note : the ground elevations are mostly in negative.
so i tried to change the invert levels to -20 m but it didnt work as well because it kept the slope as min and contained desgin using -20 m level.
another issue is conduit catalog should contain conduits that available for design.
thank you
Hello Ahmed,
Could this be a result of "fixing" the elevation of one or more elements by way of local design constraints? (for example "Design Start Invert?" = False for a conduit, "Design Structure Elevation?" = False for a node, etc).
To help solve this problem faster, consider providing the model file using one of the two options mentioned in my last message.

Dear Jess
I have over passed the issue of the conduit catalog but still i have another problem which is the message of the "conduit is above design capacity" and the maximum conduit was sized by sewer gems is 500 mm where the conduit catalog contains pipes from 200 mm to 600 m and they are all available for design so the point is why sewer gems doesn't go for the next size if the pipe size is not enough ?note that i have modified the design constraints for slopes to be tables as following
also i tried to make the slopes simple may be it prevent Sewer Gems from choosing the right size but also the same the max pipe was 500 mm only
regards
Also regarding the user notification, if the information from my previous post does not apply, check to make sure that the appropriate entries in your conduit catalog (the one with the same Shape and Material) are marked as being available for design. When you click on each entry in the Conduit Catalog, you'll see an "Availability" section, which a check box for "Available for Design".

These two issues may be related. It sounds like the Conduit Type for one or more conduits may be set to User Defined. In order for a conduit's size and/or inverts to be designed, you must choose Catalog Conduit for the Conduit type. This allows the program to choose from the available section sizes in the Conduit Catalog during design. Without doing this, the conduits won't be able to have their size nor the inverts changed from the original input values, which is likely why they remained -20 m. Try setting all conduits' type to Catalog Conduit, choose the appropriate material and select an initial size. Ensure that the Conduit Catalog is populated with an appropriate range of sizes that you'd like to the design to select from. Another thing to check would be local design constraints; check for any "fixed" inverts ("design structure elevation?" = False) that may have been accidentally adjusted.
If this does not help, please provide a copy of the model (zip up the .stsw and .stsw.mdb, if you're using the latest version) and some additional details of where to look. There are two options for sharing your model files. If you would like the files to be visible to other members, you can upload them as an attachment using the ‘Advanced Reply editor’ before posting.
