There is currently not a way to join/group multiple nodes to a structure node to match existing survey data. This node join/group capability is needed to match XYZ surveyed invert points (from field collection) and be able to use the Extract from Graphic tool to build the existing conduit network using conduits and mock nodes at the surveyed invert points. Once the existing conduit network is created, a user can use the Place Node tool to place the structure nodes at the structure top surveyed points to match the center structure locations. The surveyed top elevation at the structure node can be captured as the structure node’s ground elevation. The surveyed bottom elevation at the structure node can be captured as the structure node’s invert elevation. However, users cannot currently join/group the conduit mock nodes to the structure nodes to connect the existing conduit and node network, while matching the surveyed XYZ field data on the existing network and using the Extract from Graphic tool. Please see the attached survey data example showing multiple pipes in a structure.
