Projected selection not true round feature. (Look inside for better description)

[Anonymous]

So I ran into an issue where I am trying to helically ramp a 1/2" endmill into what finishes at .875" diameter. The problem is, this valve I am making has a cross hole. I selected the cross hole intersection as my contour selection and it projects a round circle at the correct depth of cut.  When I post out I get no IJK output and its a million linearized moves.  This is fine on 6 out of 7 of our cnc mills here. We have one mill (same control as the rest with lower options) that cant read that much code that fast and it drops out mid cut.  So the problem is I have to be careful that when the job comes through, if that machine is open the guys cant load and run the program. 

I just realized that it looks like however fusion projects a curved line selection into a single plane circle, it must be doing so as a spline that consists of a million small lines.  I selected the circle at the top of the part and just set my height at the depth I wanted and all of a sudden I get nice IJK post as I would have expected from the other selection.  In this case, and future similar cases, this is fine as I now learned what not to do, but in some cases that projected geometry really comes in handy, however, it posts a ton of not needed code.

It would be awesome if this feature could project true circles and not linearized representations of said geometry. 

See example code below and attached images of selected geometry.

Same exact thing selecting the curved selection projecting a circle
