    Circles (voids or solids) in families - need ideas

    Hello guys, I am building a family of a metal frame that has holes along the faces on the steel tubing. Think storage rack.
    The part I am struggling with is locating the circular voids on center and constraining them so that if the family flexes they can move etc.

    In other software this is very easily done since you can dimension to the center of a circle (place a constraint dimension). However you can't do this is Revit, at least not that I know of.

    The only way I manged to do this somewhat was to host each hole geometry to a reference line and then create constrains to the ref. line.
    Looking for a better way or alternate way. Autodesk the family editor needs to be more like fusion!

    You can absolutely constrain the center of circles. Select the sketch line and turn on Center Marks. Then use the Align and lock.

    You're not the only one who never noticed it. Thanks for asking so more knowledge had a chance to be shared.

    If you really want to have some fun constraining curves, check out Paul's Renaissance Revit book: Renaissance Revit: Creating Classical Architecture with Modern Software - Paul F. Aubin I went so far as to get my copy spiral bound so I don't destroy the spine.

    I had some good fun editing that book. And have some great screen shots from the Parkland days, while he and i were comparing notes. Its a TON of fun to read through.
