I'm trying to start up Inventor, open an assembly and save it to stp using API (C#).
This works perfectly fine with parts, but not with assemblies.
doc.SaveAs("fil.stp", true); // doc is an iam-file (Inventor.Document)
...gives me error: "Invalid parameter... HRESULT: 0x80070057 (E_INVALIDARG))".
I start up Inventor visually so I know that the assembly opens up correctly with all parts and subassemblies.
If I do it manually it works fine with Export -> CAD Format -> STEP (stp).
Does anyone have any ideas why or what I'm doing wrong?

Solved! by simonsson. See the answer in context.
I found the problem. Inventor was not ready loading when I opened the assembly. Thanks!
Can you try providing that full path for the output file, rather than just "fil.stp"? I tried the following VBA macro on the active assembly document in Inventor 2011 and it works for me.
Sub SaveAsSTP() Dim oDoc As Document Set oDoc = ThisApplication.ActiveDocument Call oDoc.SaveAs("C:\temp\test.stp", True) End Sub
Would it be possible to add options for the step export within the code?
Specifically, does the export step have savecopyas options that can be set just like in the dxf/pdf translator addin?
Goal: I want to preset the export options for the step file.
options I would like to "grab" & "set":
- Application Protocol: 203 or 214, then 214 alone, 214 IS or 214 DIS.
- Include Sketches (True/False I guess)
How can I access the saving options.
I want to exclude the sketches while saving as stp
