Grasshopper Rhino Components centermark issue

Centermark x and y axis lengths change independently. It only really looks correct in a perpendicular view.

Any chance a ground plane is interfering? Looks different when the Centermark component is selected:

Centermark

I’ve never seen that component before.

Didn’t understand

This centermark is at an xy plane on 10,10,10

Notice how in the perspective viewport the axis lengths change…

Video looks similar to ground plane effect but:

  • I can’t enable any ground plane effect on anything right now
  • I’m not fully awake yet
  • I don’t have R9 WIP anyway, only R8

Carry on, I’m sure you know what you’re doing.

I should have posted a file…

How would the ground plane have any effect 10 mm above the origin?

Height above world XY: Automatic

But as I said, I can’t enable ground plane at the moment. I often have to disable it.

Ok, a square around the centermark shows the issue much better:

Adding some geometry in the Rhino viewport also affects the display size of the axis.

Hi Martin -
