Weird "layer" added when opening File

This issue happens when a cad file is saved using Rhino 8 and converted to a Rhino 5 and then opened in a software called Matrix 8.0 (Uses Rhino 5). After the file is opened a weird gray layer like surface appears in the middle of the screen that you can not select, delete or move.

Has anyone every seen this or know what this layer like surface is called? or how to delete it?



Hi Roger - seems like it could be the ground plane - open the Ground Plane panel and see if that is turned on, or check in the Display mode for the viewport that shows the problem

Any luck?

Hi Pascal,

Your 100% correct . It worked. I type “Ground Plane” in the menu and then I Un Check the “Show Ground Plane” Box. And then then save the file.

I would like to make a Tool Bar Button to do this process. Can you help me and tell me what I should type in the command box to make this code?

Hi Roger - a macro to toggle the groundplane is

_-GroundPlane _Options _On _EnterEnd

-Pascal

Hi Pascal,

When I enter the Macro, “Ground Plane” turns OFF. Then I click the macro again and it turns ON. Then I click the macro again and it turn OFF… and so on…

Is it possible to only have the Macro change “Ground Plan” to OFF only and not OFF,ON,OFF,ON…

Change the macro to: _-GroundPlane _Options _On=_No _EnterEnd

Thank you !!!

I love this forum!!
