Change the World

I am trying to change the CoodinateSystem of rhino... at least for a little while

I have tried:

(ByVal pl As Plane, ByRef A As Object)

plane.WorldXY = pl

Result:

Error: Property 'WorldXY' is 'ReadOnly'.

also

(ByVal pl As Plane, ByRef A As Object)

rhino.DocObjects.CoordinateSystem.World = pl

Result:

Error: Constant cannot be the target of an assignment. (line 86)

any ideas?

I need to get the x and y value of points to rank them but I need their x and y values to be based on the input plane... not the worldXY

You can't change the coordinate system. It's fixed. You'll need to perform the coord-system mappings yourself. Create a transform matrix using Transform.ChangeBasis and supply the World plane and your special plane. Then you transform the points which converts them from world-space to your-special-space.

Or you could use Plane.ClosestParameter() and Plane.DistanceTo() to get the u, v and w values of a point in plane space.
