[slice tool snap to grid?]

February 2024 can saddened to find this thread after a little bit of googling. 😢

The slice tool feel next to useless for me in it's current state in Affinity Designer 2. 😞

I'm trying to export an icon set for my Stream Deck so need 15 square slices to line up exactly with the artwork.

The free hand slice tool is not snapping to anything.

I have tried creating non-visible boxes in the right positions and creating slices from those but then all I can export is the empty box, I can't seem to get it to export all the layers for a clice created that way.

The "Edit All Layers—allows selection of objects across all layers (rather than the current layer)." option doesn't seem to do anything. I may be missunderstanding it's purpose but my intuition was that it would indeed say what the docs say and select all layers when creating a slice.

The "Export Setup Options" as described here- - says "The following options are available in the export setup for each slice entry: ..."  IMO this suggests that you can change between these options but I can't see a way to do that, it seems these options are just different icons to show how the slice was initially made.

Part of the challange for me in this particular situation is that I have background artwork that spans across the whole grid of icons to be exported making it much much harder to create each icon as a self contained group or layer - at least, as far as I can tell, without loosing the abillity to easily edit the background layer in isolation.

Very very frustrating that there isn't a better way to do this even after all this time.

I guess my only option now is to manually place every slice and adjust the exact size and position using the Transform pallette. I'm glad I only have 15 of these to do!
