If you select many areas of a bitmap at once with the marquee tool, Fireworks reads your action as having added the second, third, fourth selection to the original selection instead of having made multiple selections. Therefore it cannot distribute the selections to seperate layers. However, if you select symbols one at a time, copying and pasting them in place in your original layer, you can then Shift + Select them in the layers panel and choose Commands > Document > Distribute to Layers.
There is something i miss here.
It seems that layers reside in folders-corresponding to the same folder icons that appear in the layers panel.
Ok i got that.
But i do not see any practical difference between having 1 layer with 2 objects and 2 layers with 1 object each of them.
If the main feature of layers is to stack objects on top of the other,from what i have understand so far, that can be accomplished with one layer too.
What is the reason for having 2 layers to achieve the stacking function.
I am confused. Can you help me with this please?
There is no technical reason for having two layers to achieve stacking function. IMHO, it's merely a matter of preferance. It's often a preferance of designers who are used to using bitmap based software like Photoshop rather than vector based software like Illustrator.
Thanks a lot for the explanation.
Now it is clear to me.
