I was trying to extract geometry control from Clipping planes in Rhino 8 and found a weird problem .  
In Rhino 8 , the point of the plane is not related with the clipping plane in a normal way. Its X axis is base off from the edge control points of the clipping plane , which make sense.  
While its Y axis point is a random number (no matter in metric or imperial) and would scale related with the plane , as you can see the 11’5 13/16" would become 22’11 5/8" when its scale up 100 %.  
Where in Rhino 7 it doesn’t behave like this . Rhino 7 is simple , it just relates with the corner of the plane , which make sense.

Is there anyway to solve this besides a workaround on the scripting side ?

Hi -

You didn’t attach any .3dm and .gh files here. In a quick test, Rhino 8 puts the “point of the plane” in the center of the clipping plane, whereas Rhino 7 puts it, as you said, in the corner. To me, Rhino 8 makes most sense. But then, neither size nor center matter much for the function of a clipping plane, so I’m not sure what you are needing this for…

Interesting, yes , the one you show for Rhino 8 is what I wish mine is showing . but somehow… its not .  
My Installed version is 8 SR10  
And here is my rhino file and gh file , which you can take a look if its something native happening to it.

@wim Did you have a chance to take a look at my file ?

I had a chance but was unable to reproduce what you are seeing in your screenshots. Perhaps you could try updating your Rhino to version 8.11 and see if that helps?

Interesting, but it wasnt release as a service release candidate yet?

I believe if you can install 8.11 if you set your Update Frequency to **Service Release Candidate** from the drop down menu.
