Hi all,
I'm struggling to get a family to work as I desire.
Attached is the family I'm working on, basically I've nested a chair family into my table family, All I want to be able to do is get the chairs to follow the corners of the table when the depth and width parameters are flexed. They seem to be able to lock to one but not the other.
Can anyone enlighten me as to what I need to do to get the nested family to lock to both ref planes (width and depth). I figured I could create layers of nested families for the chair to achieve the parameters individually, but that seems very messy.
Please help ![Winking](/images/smiles/wink.gif)
*P.S. the families may have a few unnecessary ref lines/planes as I've been trying to figure out random ways of getting it to work, to no avail)

Do you understand what family origin is? If not, then read this in your HELP:
Defining the Family Origin
Note. Best practice for the use of reference planes is to establish them in the family before you need to use them. Adding them after geometry or nested families are in is too late.

Hi Hub,
Yeah I know how to define an origin (I was messing about with it in the nested Chair family to see if it would help (again no luck)). so that doesn't really answer my question.
And yes I know to place reference planes before hand to lock my extrusion sweeps to etc. etc. I'm fine with that too.
I just need to know why I can't lock a nested family to 2 different planes without it breaking when I flex the parameters.

Instead of align locks, have you tried dimension locks?

Yeah I tried that and it failed , I've also tried stripping out all unnessesary Reference planes/lines and setting a new origin on the chair, but again no luck. I think I'm going to be stuck with layered nesting, unless someone can figure it out???

I've got it to work quite nicely now and only needed to use 1 extra layer of nesting. Still not sure why Revit won't let me lock a nested family to 2 planes though, very annoying... If anyone can enlighten me on how you go about it (and get it working) or give me a good reason as to why you can't I'd really appreciate it ![Winking](/images/smiles/wink.gif)

Take a look at this one. Moves in both x & y directions.
Read this HELP topic:

Yeah I've read that before.
The example you gave clearly works properly, so I tried to break it to figure out what went wrong and I couldn't, I even screwed up all of the ref planes naming and priorities (Strong to weak etc.) and it still wouldn't break!
I'm guessing I may have stumbled upon a glitch somehow in the family I made. because align/locking 2 refplanes on a nested family worked perfectly in the example you attached above.
Thanks for your help Hub, I guess that solves it lol... Glitch!
