Hi Brent.  I know it's trivial, but is there a way to get a double-bend stay auxiliary view to display taper from the dropout?  I can only get it to display in the middle section of the tube.  

Thanks a lot, Ben

It's a Reynolds Seatstay

It's a Reynolds 725 GX2715 single-taper, double-bend seatstay, by the way.

Showing taper in auxiliary view

Sorry. When I set that view up years ago, the centerlines of the stays were represented by a series of arcs and lines which are 100% accurate. If the taper extends into the bends, the centerlines will remain perfect arcs, but the inner and outer contours of the stays can no longer technically be represented as arcs. I made the lazy decision to represent the inner and outer contours of the stays as arcs anyway which means the taper is not being represented along the lengths of the arcs. Perhaps it is time to revisit that. In the meantime, models exported to FreeCAD do have the appropriate tube cross section located at the end of the taper.
