It worked kinda like CopyBlock and Pasteblock, but it trimmed the entities
that extended outside the area of the box you selected.
§ Call up the routine (can't remember the name), and it would prompt you to
draw a rectangle.
§ The routine would then create a wblock that included all the linework
inside the box or crossed by the rectangle.
§ It would also clip all the linework that extended outside the rectangle.
§ I think the insertion point of the new block was the lower left corner by
default, and I don't remember being able to alter it.
§ I also can't remember how it handled the naming of the wblock. Maybe it
just went to a clipboard and you pasted it into the next drawing.
I think I had it back in Acad14... Got anything like it?
