Hello, I am self trained and as such have probably developed very poor habits.

I create models that have many holes in various simple patterns but not in a way that lend themselves to linear patterns.

When I create feature, I often need to create holes in one quadrant and then mirror them over the Y axis, and then both of those quadrants again over the X axis.

I can do this easily enough by creating construction lines from the origin, but it gets tedious doing them as often as I do.

Is there a better way to mirror parts from a single quadrant, or is there a way to automatically generate construction lines that enable something like this?

Thank you!
