Thank you Michael,

I have been a lot confused.

But your last response about "If you want an independent frame try creating a new one using:"
is exactly what I need for the script!

So the cPlane1.xaxis; and cPlane1.yaxis; and cPlane1.zaxis; are not locked to a specific point in 3D space, because they are Vectors,
but they commonly are thought of as emanating from the local Origin, which is located at the world coordinate point pt.
And the three axes do correspond with the grid axes of the particular View, so the 2D points, (or possibly 3D points), can be plotted.
The world coordinate point pt, will establish the local Origin of the frame. The local Origin point is ( 0, 0, 0 )

My cPlane2 origin will be in a different location than the cPlane1 origin.

Again,
Thank you very much.

I should not have been talking about BasePt, when I should have meant origin point.
