Positioning when using Auto Placement

[Marc87dk]

I would like to know how I can change the positioning of the objects that I add with Auto Placement.
I am working with gantry placement, and while I am satisfied with the distance between each gantry, I noticed that the Auto Placement puts the gantry too much to the right. (as seen on the picture)
I can fix this manually, but it is very time consuming. I would rather like the gantry to be correctly centered with the track.

Any tips?

Press the three little dots next to Auto Placement.

Using the Translate Offset boxes you can move the gantries in all three directions.
You'll have to experiment a little to get it where you want it.
