Thank you for the Info, Metin.
By the way I like the great examples you
made with MagicaCSG. Very well done.

In the meantime I found the "Select All" button.
With this button you can select all strokes of a layer.
I should have just opened my eyes ;-)

And this way I can now put parts of an object on a
separate layer and select them if I need that.
