SewerCAD/GEMS: I currently have all my manhole invert elevations set to zero, but I do have invert elevations for all the conduits. Is it possible to set all the manhole invert elevations to be equal to the invert elevations of the outgoing pipes without entering numbers manually in the manhole Properties window? Is there a column I can add to the manhole FlexTable to do a Global Edit?
Hello Robert,
It will be easy for you to choose the option to set the conduit start and stop inverts equal to the start and stop node, and then adjust the upstream downstream manhole invert (which will adjust the conduit invert along with it) instead of adjusting the conduit inverts.
If not, see the workflow suggestions here: How to apply conduit start/stop elevations (eg. ground & invert) to adjacent nodes.
If you want the constraint-based design solver to set both the node and the pipe inverts for you based on constraints like slope, velocity and cover, you can specify which element(s) have a fixed elevation, around which the solver will design the other inverts. For example if you know the outfall's elevation and want everything else to be designed around that, choose "false" for "Design structure elevation" in the outfall properties, then enter the ground and invert elevation. Make sure the other node elements also have a ground elevation set (it will only design inverts, not the ground elevation). Here are some resources that may help you:
