Allow a data flag to be placed on a conic surface in a view per ANSI Y 14.5 example. Customer needs to define the primary, secondary or tertiary Feature of Size which happens to be a conic. The conic is built on two 180 degree arcs. The workaround is to place a datum plane perpendicular to the drawing view for datum flag placement. This does not always work. Placing the datum flag directly on the conic surface, allowing the silhouette edge to be perpendicular to the drawing view for displaying the datum flag would be ideal.
