ARC VS CURVE?
-
Does anyone notice when you offset an arc it becomes a curve entity? Which means the entity has different characteristics. Just noticed this while using center point ruby.
Center point ruby did not work on the curve entity

I hadn't noticed before, but it seems to be true.
The reason seems to be in the way the offset function works. Arcs are just open curves with all the segments the same length, and with all the vertices being on the same arc. When you offset it, this no longer applies. The offset command makes the end segments relatively shorter, and a line drawn between the endpoint of the original and offsetted curve is at 90 degrees to the first segments, and does not cross the centerpont of the original arc. It is more noticeable if you make an arc of very few segments.
