Duplicate along path, unequal divisions

[Benson Shaw]

This started with attempt to locate 2D loci on an arc with Duplicate Along A Path tool. Goal was to "divide" arc into 6 equal divisions with first duplicate on one arc end, last duplicate on other arc end, with 5 duplicates at equal arc length spacing between. I set the DAAP tool options to: Number of Duplicates = 7, Start Offset distance = 0. The result instead was 7 duplicates with the last one placed on the arc just a bit inboard of the arc end. The announced arc length (obj info palette) divided by 6 (on my external calculator) is not same length announced in the updated Fixed Distance box in the DAAP options dialog box.

I got curious and increased the unit precision out to 5 places. Same result. I divided some open polylines this way, too. Corner Point, Bezier and Arc polys divide into even segments. Spline poly did not. Sometimes the "last" duplicate did not show up.

Segment Arc command works on arcs, but not on polylines.

Same results with anti aliasing turned on.

OK, is this my system? Pilot error? A VW thing?

Any comment welcome.
