Revit Bug - Faceted Display of Curves in families

[Andrew Dobson]

There is a serious bug with the way that Revit displays some curved elements within families, instead of a smooth curve, it is displayed faceted.

A typical example is with a classical column family. I have drawn the profile of the column base in the family editor, with smooth curves, but when this is loaded into the project, it gets displayed as a series of straight lines. It also exports to AutoCAD this way.

I can just about get away with this on general arrangement drawings, but on any large scale details it just looks ridiculous.

Here is my workaround: Open the family, copy out the profile, export to AutoCAD, import into a Revit drafting view. This then looks ok, but takes forever to do.

Is there a better solution?

NB: I have submitted a support request to Autodesk about this
