Project Point to Brep Issue

Hi All,

I seem to be having an issue with project point to BREP and also intersect BREP with BREP on a particular set of geometry.  Essentially I have a list of planametric curves which I am trying to project to a set of surfaces.  When I try to extrude and then intersect those resultant BREPS there seem to be random errors where the intersect curves are not actually on the intended surfaces (see screenshot 1).

So, I tried a work around and got the vertices and tried projecting them to the intended BREP with the same exact result (see screenshot 2).  

As a step in trying to ascertain the source of the error, I attempted to bake out both the set of curves and the BREPs to attempt to try the same operations within rhino.  Surprisingly, I had no issues with the operations on the same geometry when working through Rhino as opposed to keeping it live in Grasshopper (see last screenshot).  

Has anyone experienced this?  I've attached my file, as well as the definition.  Ideally, I would like to end up with an ordered list of edge crvs (4 per projected warped "square") hosted on the BREPS so I can continue building geometry for each one of the instances (they will eventually be skylights).  

If anyone can help - I would greatly appreciate it!

Thanks!!
