Create MultiViewBlockReference with .NET

[mgreven]

Hello,

Does anyone have a example how to insert a MultiViewBlockReference with .NET in ACA?
I have a MultiViewBlock created with the Name TestBlock and want to create a Reference in the drawing.

For so far as i discoverd i have to make a new MultiViewBlockReference object and set the defaults.
But how do i set the insertionpoint and the the link to the MultiViewBlock definition?


Regards,

Marco

Hi mgreven!
Try this:
