Well, I found in the support docs this...
To prevent clipping of segments at the start or end of the path:
It is possible to automatically scale segments so that they fill a path with only whole segments, avoiding clipping at the start or end. Assuming you already have a segment in the default input:
From the Generator’s properties, go to Rules>Default and set the mode to Adaptive.
Set the Adaptive Percentage to control the minimum length of remaining space before a new segment is added (see the section below for a more detailed explanation).
Tried it out and it worked, but it completely changed the coursing to stacked. Also (see pic) the coursing switches from common to stacked from one end of RC object to the other end.
Please advise, thank you!
