ReleaseComObject vs FinalReleaseComObject
When freeing up COM objects in your Inventor add-in, don’t use FinalReleaseComObject() as it will badly affect other add-ins. It fully releases the object, so that other add-ins previously referencing it will not be able to access it either. Here is an example. AddIn1 does this when being unloaded: public void Deactivate() { Marshal.FinalReleaseComObject(m_inventorApplication); m_inventorApplication…

Hook up a chain using iMate’s with MatchList
I already had a blog post on Hook up a chain using iMate’s, but I was recently asked about more iMate related API samples, so I thought I could also demonstrate the usage of iMate MatchList. In theory, when using a MatchList, the iMates in the various components should be matched automatically when using the…

Run commands from the “Text Commands” panel
As mentioned in this article already, you can run registered Fusion 360 commands programmatically as well. You can also do it without creating a script or add-in, by using the “Text Commands” panel: In this case we are using Python, so make sure that the appropriate radio button is selected: import adsk.core, adsk.fusion app =…

Using Visual Studio to Debug iLogic Rules
In Inventor 2019, we have incorporated an experimental mechanism that allows you to use Visual Studio to debug your iLogic rules. It is not a seamless experience, but nevertheless is an effective technique. We are looking for feedback as to whether the quirks in the experience are tolerable, versus the benefits of being able to…
