I am building a curtain wall door family and I am having problems getting the symbolic lines to display correctly. In a standard door family I can draw the Elevation Swing (projection) lines on the exterior elevation and they also display on the interior side. But in the curtain wall door I have to draw these symbolic lines on both elevation. In addition, these symbolic lines don't display in a 3D view for a standard door family, but they do display in a 3D view for the curtain wall door family.
