Uses for the new "Symmetric" Constraint

I'm absolutely thrilled that a bi-directional constraint has been implemented in Onshape.
I have lost count of how many uses a similar tool in Solidworks had.
Here's just one example (apologies for the lousy animation - I used Licecap - not sure why it drops so many frames)
The objective is to position isolation partitions between termination posts, which is quite a labour intensive task, using conventional construction techniques. It could not be simpler when the position of the symmetry line can be driven from edge geometry as shown.
ON EDIT: I'm really disappointed with the animated gif; it makes it look like a nightmare.
It's just four clicks to reposition each line;
I encourage anyone who's interested to give it a try

I just tried it on a model I was working on, mentioned in another thread entitled "TIP - Diagnosing Merge Issues"
I didn't expect it to work by clicking on the highlighted model edges to produce the inferred line bisecting the two axes of the cylindrical recesses, and to say I was surprised when it worked would be an understatement.
This line can then be used as the axis for the linear pattern of the guide posts, shown in the other thread.
For clarity, I've added a screenshot a couple of posts down this thread, which shows the bisector viewed normal to the plane on which it is requested and drawn
Please @lougallotell the secret to her beautiful gifs.
One of the screws fell out of my spectacle frame today - maybe it's time to visit the optometrist for a new prescription!
I'll have a crack at re-recording that animation... I might try recording a grey or black frame for a short period, too, to indicate the end of the loop, 'cos I sometimes find it a bit hard to follow in cases where the phasing is not obvious.
