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'

'refpt'

Error when attempting to make a fluid delivery time file...

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.

When opening HydraCAD, you only receive this error message and not a HydraKEY error with the golden X.  If you receive a HydraKEY error, search for the linked HydraCARD in that message box as it takes priority.

Security Error:  One of the following conditions is likely;

HydraCAD is unable to function under these conditions

• Lock database needs updating in HydraKEY
• Accounting flag on your account
• Hardware lock not plugged in
• Extra ACAD.RX file found in folder in Support File Search Path
• Sentinel driver is missing
• InstallPath registry item set to wrong drive

After AutoCAD opens, press F2 to view the command prompt, see if the text below appears.  If yes, see solution 1.

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.

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.
