Changing rhino unitsystem

Hi all,
I am having troubles trying to convert one script from python to c#. I realized that I have to change all of the structure. The code is about units. I would like to have one tool that notify me which units I am using in Rhino. here there are the scripts that I made. Also, I would like to know what the syntax for units in rhino is.

and here is the python script that I want to achieve in c#

thanks in advance for your help.

Hi @dale
thank you very much. It was very helpful. Also, I would like to know if there is any way to change the units from Grasshopper to Rhino? and alert me whenever I am not using feet or inches.
thank you Dale!


Hi @santi.canorestrepo,

To modify the Rhino document’s model unit system, use RhinoDoc.AdjustModelUnitSystem.

To be notified when the Rhino document’s model unit system has change, you will need to handle the RhinoDoc.DocumentPropertiesChanged event.

Dear Dale, how can I do this from a c++ plug-in? I don’t see AdjustModelUnitSystem as declaration. Is it under a different name?

Here is an example.
