Remember, when adding anything into a family, create Ref Planes first, then
dimension and add parameters. Then 'flex' the model. If it works as
expected, then add geometry, locking to the Ref Planes.
Sounds like you built the muntins first, locked them to other geometry (the
frame), then tried to go back and make more Ref Planes.
I'll take a look at your attachement, and see if I can help....

> I am trying to create a new family out of existing double hung window
provided in an Autodesk Library. I made a solid and extruded it to the
height of the window frame. Then locked all ends to the frame. When I change
the window height in the Family Types parameters the horizontal mutton moves
off the center. When I created a guideline (ref. Plane) eq./ eq. and tried
to lock the edges to it and then change dimensions of the window it gives me
a message that "Constraints are not satisfied". How do I adjust the middle
horizontal mutton so it always stays in the middle no matter how tall the
window gets? Please see attached file. Thanks.
