Hello,

Need help  and could not find a solution for it.

I have  the ID of non rectangular view port and I need to find the Polyline attached to it.

How do you do that ?

Thanks,

Hi, Janet!

Please attach a simplest dwg-file with such viewport and correspondent Polyline.

 

P.S.: Maybe method Viewport.NonRectClipEntityId can help you?

Hi,

 

Once you have a viewport ObjectId, use viewport.NonRectClipEntityId (that should be not ObjectId.Null) to get its non-rectangular viewport, see the following code snippet:

 

transaction.GetObject(viewport.NonRectClipEntityId, OpenMode.ForRead) as Polyline
