On Land

The Active Layer palette is accessed on a submenu of the Layers submenu, which might be on Options (9) or Document (10) or somewhere else by now. You mean the Quick Layers palette? No. Active Layer.

This palette does exactly one thing, and I use it for exactly one purpose. It switches between the default state of 'Individually Set Layers' and the weird state of 'One Active Layer for al Element Types'. That is, it can set all the tools to the same layer in one go. And it can put them all back to the layers they had.

No, I wouldn't want all the tools on one layer, ever. I don't know why they made this thing, but here's what it's good for. Attribute Manager will report that a layer is in use if it is the current default of a tool. So you can't really tell if an element is on the layer or not.

So, use Active Layer to set all the tools to the Archicad layer. Set the palette to 'One Layer' and then set any tool to the Archicad layer.

(The other source of phony checkmarks in Attribute Manager is Favorites.)

When you close the Active Layer palette, or close a project where all the tools are 'One Layer', you'll get a dialog asking if you want to keep the One Layer, or Revert to the individual layers. You should choose Revert. (Of course, if you've deleted most of the layers, there's nothing to revert to, but it doesn't matter.)

It is not possible to delete the entire Favorite list at one time. You can only delete them one at a time, which, if you have a lot, no thanks.

But you can write over the entire Favorites list with another list. If this list happened to have, say, one item on it, well that would be pretty easy to delete.

We have the Favorites file 'Blank.prf' for this purpose. It resides at 3 Resources / AC / Favorites. It consists of a Favorite for the Hotspot tool, Archicad layer, pen 10, that's it.

On the flyout on the Favorites palette, choose 'Load Favorites', and open the Blank.prf file. You will get a dialog offering to merge or replace the current list. You want to replace. (Merge adds the new list to the old.)

Delete that hotspot fave and you've got your blank slate.

Why delete the Favorites? It helps clean out attributes. Attribute Manager will report that an attribute is in use if it is part of a Favorite. With no Favorites, it's one less place to look before you're sure you can delete something.

And of course you can clear them temporarily. Save the Favorites you are using, clear them, do whatever you need to do, then load your saved list back.
