Position a Group Using a Child as the Anchor

Hi,
I want to position a grouped set of objects in LightBurn using one specific child object as the group’s center. For example, I have multiple holes in a pattern and I’d like to choose one hole as the reference center so the entire group is positioned from that point. The goal is to align the job precisely, then flip the work and re-align for accurate double-sided cuts.

How can I make LightBurn use a selected child object’s center as the anchor for positioning the whole group?


The Red circle is the one I want to anchor around.

Group everything except the child object. Select the group then shift select the child. Use the bullseye or center horizontally then center vertical.

No that groups everything around the child,but it did help a little. I want to make the child the origin so that it becomes the center of the group and if I move said child to the center of the work area all the other parts move equally and that child is in the center.
With what you sugguested, I draw a rectangle around the objects and then select the rectangle and the child object I want center and click the bullseye. I then enlarge the rectangle (using the number fields and not the drag points) with the center spot selected as origin. Then selecting everything I can then move to the center of the work area and the child object (In AI it’s called the Object Key) is now central with all the other objects around it positioned correctly.
The issue here is that you have to faf with making this extra temp rectangle and make sure it’s enlarged enough to encompass all the the children. Was looking for a simpler way. But now that I know about the bullseye it did help.
