spirals

[Earle D. Knowles]

I am using SurvCADD XML to create a metric roadway alignment using spiral
curves. The centerline file looks ok and converts to a Leica .gsi file that
looks ok, but if I draw the centerline with Centerline to Polyline, I get
very strange angle points at the TS, SC, CS, and ST stations. Is there a
known bug in the routine? or does someone know what I might be doing wrong?
