Determine File Type for iLogic Rule

Issue:
You need your iLogic code to check to see if the file type is a part file first, before running. Otherwise it generates an error. Is there a way to do this?

Solution: 
Here are a couple of quick code snippets that demonstrate how to do this using the DocumentType enumerators:

'start of iLogic rule - - - - - - - - - - - - - - - - - -

doc = ThisDoc.ModelDocument

 'check file type

If doc.DocumentType = kPartDocumentObject Then

MessageBox.Show("This is a part file.", "iLogic")

Else if doc.DocumentType = kAssemblyDocumentObject Then

MessageBox.Show("This is an assembly file.", "iLogic")

End if

 'end of iLogic rule - - - - - - - - - - - - - - - - - -

 

'start of iLogic rule - - - - - - - - - - - - - - - - - -

doc = ThisDoc.ModelDocument

 'check file type

If doc.DocumentType = kPartDocumentObject Then

'do nothing

Return

Else if doc.DocumentType = kAssemblyDocumentObject Then

'do something

MessageBox.Show("This is an assembly file.", "iLogic")

End if  

'end of iLogic rule - - - - - - - - - - - - - - - - - -

Here is a list of all of the the DocumentType enumerators available in the API:

kUnknownDocumentObject
kPartDocumentObject
kAssemblyDocumentObject
kDrawingDocumentObject
kPresentationDocumentObject
kDesignElementDocumentObject
kForeignModelDocumentObject
kSATFileDocumentObject 

kNoDocument

Here is another version of the rule that will report the file type and check to see if a sketch is active. This example rule will report the file type even when editing within another file type. Meaning that if you have a part file active within an assembly, this rule reports that it is a part file.

'start of iLogic rule - - - - - - - - - - - - - - - - - -

Dim oDoc As Document

oDoc = ThisDoc.Document

If oDoc.DocumentType = Inventor.DocumentTypeEnum.kPartDocumentObject  Then

            If Typeof ThisApplication.ActiveEditObject Is Sketch Then

            MessageBox.Show("You have a sketch active in a part file.", "iLogic")

            Else

            MessageBox.Show("This is a part file.", "iLogic")

            End If

Else If oDoc.DocumentType = Inventor.DocumentTypeEnum.kAssemblyDocumentObject Then

            If Typeof ThisApplication.ActiveEditObject Is Sketch Then

            MessageBox.Show("You have a sketch active in an assembly file.", "iLogic")

            Else

            MessageBox.Show("This is an assembly file.", "iLogic")

            End If

Else If oDoc.DocumentType = Inventor.DocumentTypeEnum.kDrawingDocumentObject Then

            If Typeof ThisApplication.ActiveEditObject Is Sketch Then

            MessageBox.Show("You have a sketch active in a drawing file.", "iLogic")

            Else

            MessageBox.Show("This is a drawing file.", "iLogic")

            End If

End If

'end of iLogic rule - - - - - - - - - - - - - - - - - -
