Unknown *invalid_ skipole* 3D Risers HydraCAD v50

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

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.

Using negative floor elevations and drop windows with specified lengths, drops give a warning that takeout was greater than it's length, when going to 3D.

Raising to 3D and you get this error;

Exception Occured at AddURLToHyperlinks :: HydraHeads

System.Runtime.InteropServices.COMException (0x80040154): Retrieving the

COM class factory for component with CLSID

(REGDB_E_CLASSNOTREG)).

Trying to get an elevation but the results are either 0 or an incorrect value

This result should report 3000mm, instead it reports 230mm

This should report 3000mm, not 0mm

When raising to 3D (S3D command), you get a yellow circle with the message "Takeout of fitting does not match takeout expected for a "??????".  Change fitting of fabrication method"

When closing a drawing in 3D, and later re-opening and returning to 2D, some of the drawing symbols show up looking like outlines (Hangers, Sprinklers, etc)

When raising to 3D, you get the following error;
