Show Message Box Before Saving a Part

[isocam]

Can anybody help?

Is it possible, using a Python script, to show a Message Box before saving a part in Fusion 360???

For example, 

Say I have created a simple sketch and extruded it.

I now want to save it.

Normally, I would press "SAVE" and manually enter the name of the part (Default shows "Untitled").

Is it possible to show, for testing purposes only, a message box saying "Hello World" before the "Save" dialog POP-UP box appears?

Many thanks in advance!

Hi @isocam .

This can be done by using the documentSaving event.

Based on the sample add-in here, I modified it to a minimal state.
