Adding options to a custom command in Python

Scripting
1

Hi all -

I’m looking for a pointer or an example of using command line options in a custom command. I’m sure it is out there - I just can’t seem to find it!

In the Rhino Python Editor I used “File->New>Command” and my command works great, but I’d like to add an option(s) on the command line. So when I run the command, I’d like to see something like:

Select object to analyse (Density=7850):

When I click on the “Density”, I’d like the option of entering another number.

Pointers anyone?

All the best,

Tom

Hi @piroshki,

You can add command line options to any getter - something that inherits from GetBaseClass. If you look at this class, you’ll see a number of AddOption<something> methods you can use, depending on what you’re trying to do.

For example:

import Rhino

def TestTomD():
    density = 7850
    density_option = Rhino.Input.Custom.OptionInteger(density, 0, 9000)
    
    go = Rhino.Input.Custom.GetObject();
    go.SetCommandPrompt("Select object to analyse")
    density_index = go.AddOptionInteger("Density", density_option)
    
    while True:
        rc = go.Get()
        if rc == Rhino.Input.GetResult.Option:
            if go.Option().Index == density_index[0]:
                density = density_option.CurrentValue
                continue
        elif rc != Rhino.Input.GetResult.Object:
            return
        break
    
    print("Object: {0}".format(go.Object(0).ObjectId))
    print("Density: {0}".format(density))

if __name__ == "__main__":
    TestTomD()
