DrawingViewHatchRegion is not defined Inventor 2022 .NET 4.8

[lmc.engineering]

Hi all,

As the title, I seem to be having an issue getting hold of the DrawingViewHatchRegion object in visual studio. I note this was added as of Inventor 2022 and appears  I am up-to-date with the Inventor object Library & .NET version, yet I can't figure out why I can't use it? Am I overlooking something?

Cheers.

Hello

What means can't use it? Is there an error message like "Type undefined" or something?

You need to add a reference to the Inventor 2022 Interop.dll. Earlier versions don't know this object. If you don't import the Inventor Namespace in your class, you need to add the namespace to the variable declaration like

Dim oHatchRegion as Inventor.DrawingViewHatchRegion

It turns out that I'd failed to update the Autodesk.Inventor.Interop reference. My mistake!

Thanks
