Comments, Questions, and Answers related to AutoWrap() Messages in AutoPIPE Vessel

Problem:

The following appears when trying to generate a 3D AutoCAD drawing using AutoPIPE Vessel, why? user tries to generate the drawing (Execute Drawing Generation option) which ends with error:

Null IDispatch passed to AutoWrap

AutoCAD 2021 not registered properly

Solution:

Reason 1: In this case, the problem is the administrative restrictions on the computer given by the IT department. The export of the model to Autocad 3D dwg works with full authorization. 

Reason 2: AutoPIPE Vessel does not support AutoCAD Lite to export the drawings. You will face this error in case you choose AutoCAD Lite for drawing generation. Workaround here is, select other CAD software (ex. AutoCAD, Microstation, Bentley View etc).
