New preview for 2018?

[Buckeyelights]

First, thanks to everyone, especially the “how-to” videos, those are a huge help. 
Last year was my first year using Xlights for our display and it’s about time I get started sequencing this years layout.  I typically change some things around, add a few new props and switch out others to give the display a slightly different look.

A basic, newbie question: When I create a new preview for 2018 layout, how do I get some of the models used in 2017 layout to appear in the new preview?  Should I delete the models I’m not using, save that layout, and add new models?  Or is there a way to pull the 2017 models into the 2018 layout?

Is there a video that I've overlooked that shows the best way to modify an old layout for a new one?

Tks!

I recommend you do not use the New Preview feature to represent the same layout from different years.  The best way is you just copy your show folder like I used c:\xLights\2017\Christmas and now I'll use c:\xLights\2018\Christmas.   Just make sure the date "2018" is not the last part of the file path.

Thanks Gil.   I have created a new show directory for 2018.  So the best way to modify the layout is to delete and add models?

Tks!

Delete, Add, Modify existing are pretty much the only options.
