Unknown *invalid_ skipole* 3D Risers HydraCAD v50

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

{44D62FAE-67A7-4131-BF38-489CDFE44738} failed due to the following error:

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)
