When running an autolist, you're no longer getting the listing tag IDs such as MAIN A.1, MAIN A.2, MAIN A.3, etc show up on your drawing.  It only shows the original tag of MAIN A 

Same can be said for line tags #LN1.1, #LN1.2, etc

When raising to 3D, you get the error message, "Error loading the Error GUI has occurred.  How ironic."

The drawing will raise to 3D, but you won't see the error dialog window.

Trying the Show Model Errors command (SME) produces the same error

Pipe fittings in certain views were grayed out and could not be selected, making it impossible to edit or work with them.

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 possible

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.

Could not find file HCAD_ENV.INI

Is 2024; error: no function definition: PRINTEM

When raising to 3D, the drawing hangs.  On the progress bar at the bottom, it may be stuck at, "Creating entry for mains database"

If you turn off the Show Fittings in Model option found in the 3D Modeling Settings window (3MO command), it likely will create a model.

The only option is to End Task AutoCAD to stop the process.

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.

Drawing successfully elevated to 3D. No errors were found

*Please note, while the Demand summary at the top shows D3 as a point, since D2 and D3 are the same value, the graph will only show point D2.
