RE: [PROTEL EDA USERS]: Moving problems

Hi Les,
I know this bounding box. It is always there when the selection reaches a
certain size (or if you move the selection faster than the system can
calculate). But that makes no difference to the move action itself. Move
selection works as stable as if you see what you're moving. It is, in fact,
a little disturbing when the box seems to be larger than the current
selection, but this is caused by hidden strings and similar things. I face
this everytime I build panels with "move selection" or "paste special". 
But Phan Le describes a different phenomenon, if I understand him right.
I don't think he means the bounding box you mean when you're actually moving
the selection. I rather think he means the keep out line of his board that
is 3mil off after the move is done. And that would mean when taking the
selection to the cursor his cursor snapped to something else than the
selected snap grid.
Moving gerbers is nothing else than moving only primitives, mainly tracks,
pads and arcs, that are no longer grouped together in components. The
bounding box you describe should then surround exactly the structures you
see if all layers that contain selected primitives are turned on, because
hidden strings are not processed into gerber data.
