Some commands are not working in rhino tools installed in Rhino 6


I just installed section tools in rhino 6. I have created a section and also projected it into a layout via Create Sections 2D layout. The thing is that Clear one section from view and Clear All sections from views commands are not working. I am getting unknown command. The result is that I cannot delete the remaining section layout. What is going wrong?

Thanks in advance!

Is the plug-in Loaded and Enabled?
Also, please run the Rhino command SystemInfo and post the result here.

Hello - can you please run the SystemInfo command (Help menu > System information) and copy/paste the output here?


I really appreciate your immediate responses. I apologize for not replying earlier.

@wim , Yes I believe that it is already loaded and enabled, otherwise I could not even use one of the commands available. Am I right?

@pascal , I am giving the result of the SystemInfo command below.

Hello - the first thing to try is to download the latest version - Help menu > Check for updates.


Is Undefined 6 Undefined some kind of trial version or is it the new Corporate version?


@pascal Unfortunately these days I live in a village and I have limited access to internet to download the updates, so this is not an option. I suppose that for my current project I can move back to my Rhino 5 academic version.

@siemen I am not aware of any corporate version, does a version like that really exist?

Thanks a lot, I will return to this when I will be able to update

@zabrielza, your first screenshot shows Undefined 6 Undefined which is believed to be a cracked version. Corporate edition == cracked, is what @siemen is hinting at…

@jesterking, thanks for the info. I admit that I am a bit confused as I believe it is a trial version. I am going to repost here in a few days that I will have installed the trial version and have tested the section tools. Thanks
