I’m distributing point along a rectangle curve using the ArrayCrv command. The curve is perfectly flat and on the cPlane. When I distribute the points along the curve, the distance between then is different from what U specify in the command window. This happens regardless which “transform” option I select "e.g., freeform, road, etc.). And then sometimes it’ll work fine, consistently spacing points around the rectangle at the specified distance. Any idea what’s going on?
Here is a 3dm file illustrating the problem.

This first image shows the command setup.
This second image shows the result. The grid circles are 17.5’ apart on the X and Y axes so the arrayed point should be equidistant from the grid circles around the curve as I specified a distance of 17.5’. For some reason, however, the distance between the distributed curves is around 18.6’.
This final image shows the outcome when the ArrayCrv command does what I expect, spacing the objects at a consistent 17.5’ from one another. As far as I can tell, there is no rhyme or reason as to why it works as expected sometimes and other times spaces the objects at a different distance than the one specified.
