Draftsight question resetting size to original view and borders

I'm new to draftsight.

I have a problem with getting the layout reset back to a original drawing.

We do communications wiring and need to identify location numbers for customers. This includes renumbering the drawings.

I have a CAD drawing that we only edit the existing info and (changing numbers and moving around locations).

I edited the existing drawing and made my changes and now I can't get the layout back to where it was showing the print borders and sizing to scale.

Could realy use some help on this I would rather not start over if I don't have to.
