I am trying to make a revolving door family for a curtain wall. I have made the cylindrical enclosure for the doors that sizes to the curtain wall grids when loaded, but cannot make the door panels to size, unless they are in the same plane as the curtain wall. I want to make the revolving door to have 4 panels (ie 90 degree spacing) or 3 panels (120 degree spacing). How do I lock these panels to size to the grid size?
