Problem with opening dxf as 3dmodel in Inventor

[MaciejWojda]

Hello, as in written in title, I try to open dxf as 3d model in Inventor.

The code is like below:

Dim OpeningOptions As NameValueMap
Set OpeningOptions = ThisApplication.TransientObjects.CreateNameValueMap
OpeningOptions.Value("ImportAs") = "3DModel"
Set invDoc = ThisApplication.Documents.OpenWithOptions("C:\test.dxf", OpeningOptions)

 I am getting error: Method 'OpenWithOptions' of object 'Documents' failed.

Is it correct way? Am I missing something?

Thanks
