1. Inserting a hydraulic reference point doesn't erase an existing ref point at the same location

2. New ref points in HydraCALC are not using the values of the HYD ref points.

AutoCALC is creating extra node points where there shouldn't be.  In the image below, node 45 shouldn't be created as there's neither a flowing head nor a change in diameter at that point.

'extra node'

'extra ref point'

'extra reference point'

Double-clicking your HydraCALC icon makes nothing happen.  You do not see HydraCALC open onscreen nor on your taskbar.  

If you open your task manager and see the app "Hyd_prog.exe" open but not on your taskbar, then the application is stuck in purgatory.

If you see entries here, use END TASK to get rid of them.

Another option may be that it's on the taskbar but not on your screen.  That means it's open but offscreen. 

See this HydraCARD to fix that issue;  HydraCARD 565 only AFTER you've checked on the solution below.

Upon starting the Show 3D command (S3D) the drawing immediately switches to SE isometric, reports no errors but no 3D piping is visible.  Even newly drawn pipe won't elevate.

After buiding your 3D risers, raising to 3D, exporting to a Persistent Model and Navisworks successfully, your 3D riser is missing, with the exception of the skipoles

Your layers are on and the 3D_DETAIL layer is present, unlocked, thawed and visible, you just can't see the pipe and fittings.  The one customer reporting this said they disappear if the drawing is closed then re-opened.  They'll be visible in viewports as well, just not in 2D view.

When using 'Publish selected layouts' or doing a batch plot in AutoCAD 2024, the riser nipple/vertial pipe does not display correctly.  It'll either be missing outright or a proxy bounding box will be in its place.  If you plot a single sheet, it works fine.
