Subassembly Composer inverting arcs when changing sides

[Prostang]

I am building a subassembly of a mountable curb that has two curves.  I have it working well in the "default side", but when I flip it, the arcs invert. and mess the entire subassemply up.  I am going from one "PC" and creating the center of curve.  I then create the "PT" but turning the desired angle at the distance of the radius.  Then create the arc using the standard method.  Any help is greatly appreciated.

Thanks,

Mike

So I figured this out.  My issue was that I was not using a reference point when establishing the "PT" or even Mid point of curve (later trial).  Once I set the reference point, I recalculated the angle to turn and VOILA!

I stumbled upon the same issue while creating one of my own subassemblies. It appeared that, upon mirroring, all the DX,DY operations within the points went well, but I had one Angle-Distance point creation, without a reference point, that was being messed up. After some tests, it seems that angle rotation without specifying a reference point is not mirrored as expected, so that an angle of e.g. +45 degrees goes to the Bottom-Right instead of the Top-Left as expected by side flipping. 

I fixed it back then by making a decision to change the angle of the created point based on the Side parameter, and add 180 degrees to it if the Side was Left. This fixed things but your reference point solution was more elegant.
