deleting construction geometry help

[JAZZCNC]

Ok I'm under standing more now.!!

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.

You can't delete any geometry if it is related to another operation and if you do then that operation is affected which is why you lost the holes etc. In this case just Hide the sketch with construction geometry on it not delete it.

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

Same thing happening here. The sketch with construction geometry is related to the Crvpattern2 so if you delete the sketch you affect the pattern and it is removed. If you hide Sketch8 all willl be correct.

jazz thank you very much for that, spent a couple of hours on it tonight and picked up a few more issues to iron out on the way.
I was also mirroring the tem incorrectly meaning any changes were not being replicated. Think im on top of that now. tanks mate.
next challenge coming soon
