I feel like I was doing so well with ASM3, but have been pulling my hair out for hours now.
I've got two parts (A+B). I want...
one side/surface on A to be 5mm from a surface on B - can do with PlaneAlignment
one side on A to be 15mm from a surface on B - can do with PlaneAlignment
the other axis to be center aligned with each other - totally stuck with!
I've added centre lines to the surfaces of both parts in the hope that I could find a constraint with those and maybe the edges which would make them equal... but just can't find anything.
Have you tried "Symmetric Line" (to make two points symmetric about a line) ?
You could use two end points of one line symmetric about other line (times two, to get both centre aligned).
PS how big is your file? have you thought about attaching it? so that someone might have a go at trying it?
I am using Link branch and Assembly3
you can also download ... and try it here
excellent Assembly3 tutorials here

That does make sense... but tried... and nope... FreeCAD says nah. .
Sounds a good approach though, will keep on poking and prodding along those lines.
Looking at your model, your centrelines are sketches?
For the constraint I am suggesting the 3rd element needs to be an edge/face with a planar surface, so this will not work
Simplest way would be "Plane Alignment" with an offset?
Like so?:

Yup, centerlines are sketches.
The PlaneAlignment is as far as I got... but for that, you'd have to manually calculate the midpoint to centre align. I was hoping there was a constraint to ensure the part was centered along one of the axis (but not the other two, as one is for specific 5mm risers and the other to push the battery box up to one side where I can punch holes for the risers).
Thanks for trying though, I appreciate you taking the time!

You are welcome - enjoyed this little challenge
It is very powerful workbench... I like it very much.
Same... nice to learn a few things here and there.
Even exporting was a bit of a learning exercise, as I try to keep re-usable parts in a totally different folder tree, so uploading initially seemed a bit of a nightmare... but found its actually quite easy to re-reference a file if it's moved .
Assemblies are definitely the way forward... why redraw a battery box that you've ordered a few of when you can just reuse it
