can anyone help please?
I have created a part which use geometry to create a linear pattern, just a series of holes.
I then mirrored the part to produce left and right, when I noticed the construction lines for the holes I deleted it.
this removed the holes from the initial part, the mirrored part.
when i deleted the initial part to keep my new mirrored part, it left a square of construction hanging in the middle of the page.
deleting anything removes the holes from both parts.

thanks, Paul
