How do I view an event sheet outside the project?

I am new to Construct 2, and I've develop 3 games so far and seems to work well, however my 4th game on development is struggling due to some aspect to the game (i.e. Flying Enemies) But the asset pack gave a demo which was made in Construct 2, and the file also gave some event sheets, I don't know how to open or put the even sheet. I think it's not a feature in Construct 2, if it is, how do I do it?

If I get it right, you want to use an event sheet from the asset pack in your own project, right? If that's the case, just create an empty event sheet on your project, select all events from the other event sheet, copy and paste into your empty sheet.

You will need to have all variables and objects, with the same names, in your project, though, or it won't paste.

Hope this helps. Cheers!
