AutoCAD Based HydraCALC (Ribbon/Toolbar/Location)
Description:
There is a 3 pipe connection at node point but all 3 change marks are the same. Use Velocity Pressure Input error
When using velocity pressure, an Input error dialog box appears stating, There is a 3 pipe connection at node point ??, but all 3 change marks are the same. (?? could be any node point in the calcs.)
A node point appears in a calc for 3 or more pieces of pipe with the same input type for all. In Velocity Pressure calcs, Input Types are used to track flow direction in a straight flow pipe. The Input Type for the pipe that changes flow direction needs to be different.
