Creating Plane through 3 Points in featureScript

Does anyone have any tips for creating a new plane through 3 points. Have not had any luck with all test attempts of cPlane, opPlane, etc.
This at least creates a plane just not the correct one...
Any tips appreciated!
var b = vector(32, 56, 0) * millimeter;
var a = vector(88, 0, 0) * millimeter;
var c = vector(88,56,50) * millimeter;
var _origin = (a+b+c)/3;
var _normal = cross((c-a), (b-a));
var newplane = plane(_origin, _normal);
This at least creates a plane just not the correct one...
Any tips appreciated!

Really? That looks correct. Posting a link to a version of a shared document would help debug this, if indeed it's the wrong plane.Ilya Baran \ VP, Architecture and FeatureScript \ Onshape Inc0

It looks like the plane is correctly going through a b and c and the points themselves are in the wrong place.Ilya Baran \ VP, Architecture and FeatureScript \ Onshape Inc0

Alright, I will try and rework the points. Thanks for taking a look!0

Looks like I got some of the y and z coordinates mixed up, correct plane would be:
a = (32, 0, 56)
b = (88, 50, 56)
c = (88, 0 ,0)0 -
Would be nice to have world origin & coord.
Y is into page.

Yes my original coordinates were with respect to the front plane (my error), basing them relative to the top plane fixed the issue.0

I was having a hard time keeping it straight and getting the coordinates correct. Looking at the triad helped me follow along.
