Stay safe, and don't let the hurricane run off with you (or your house)

More videos are always welcome. We all have different ways of presenting things, and there are lots of topics out there not covered by anyone yet. And time is always an issue for us all, so the more people making videos, the more topics can be covered in a reasonable time.

It is a great map. But when I opened it, I did notice it uses a custom Marble bitmap in the background, which makes it incompatible with the atlas. Not an issue for this challenge, but if your intention was to provide it to the atlas, that background will need to be changed.

There are no finished tools that does this, so you would have to do some manual drawing. If you have/make a single stair symbol, you could use the Symbols Along command to place them along the wall at appropriate distance/angles, and it even allows for a constant modification in scale if you want to use the effect from this image, i.e. that the stairs gets smaller and smaller to provide an illusion of them going down..

Very nice. Love the use of color key. The disadvantage with color key is that you can't really view the map at all with effects off, but it is a great effect to do a lot of things quickly and easy to change later.
