Unspecified error (0x80004005 (E_FAIL)) when LoD of drawing view is not Master

[Anonymous]

Version of Inventor - 2019.
I have some rules in drawing, when level of details of base view (assembly view) is set as not Master I get error: Unspecified error (0x80004005 (E_FAIL)).

I determined that the error appears here:

Dim thisDrawModelDoc = ThisDrawing.ModelDocument

 after that I can't use this object, for example:

thisDrawModelDoc.update

results in error. Saving document - fix this trouble, until i change somthing in assembly (bill of materials for example).

I've tried this on several computers, it's the same result.

How can I fix it? Thanks in advance.

trying to edit a documents level of detail while a drawing is open can become a problem. For example you are using the master LoD in your drawing and you are trying to edit the LoD in the model. Inventor cant handle that. When you do this as a user you get a warning like this:

But when you do this with iLogic then you will get unspecified errors.

You could try to set the LoD in your drawing the same as the LoD in you model. (or the other way around.)

Really. Error appears when in model activated LoD different from in drawing. Is it possible to get around this problem by iLogic?

Update! Error appears after making any changes in model, even when model and drawing documents have the same LoD. After saving drawing document, there is no error.
