I need a list of predefined numbers to choose from or to input a custom number.
I assume I have to use Rhino.Input.Custom.GetNumber()
But numbers won’t work with AddOption
So I don’t know how to do this.
Thanks for helping.
Hi @Bogdan_Chipara,
that has never been possible since you’ll need to be able to enter numbers to the prompts. You may add a letter prefix eg “X_100” to circumvent it, though. To test if an option name qualifies for beeing valid or not you can use:
import Rhino
text = "100"
print Rhino.Input.Custom.CommandLineOption.IsValidOptionName(text)

Hi @dale
Is not the same.
I need a list and the option to input a custom number.
GetOption works with AddOptionList
GetNumber doesn’t work with AddOptionList
@clement adding a prefix will not solve the issue, i still need to have the possibility to input a custom number instead of the ones available in the list.
Hi @Bogdan_Chipara,
AddOptionList works with the same with “Get” class that inherits from GetBaseClass. So I don’t understand your comment.
If you have code that doesn’t work for you, then please provide.
Thanks,

Hi @Bogdan_Chipara, you might do this using GetOption and AcceptNumber:

I guess i hacked the System using a hairspace:
import Rhino
def DoSomething():
go = Rhino.Input.Custom.GetOption()
go.SetCommandPrompt("Choose or enter a number")
go.AcceptNumber(True, False)
for n in range(10, 310, 10): go.AddOption("{}{}".format(u"\u200A", n))
while True:
get_rc = go.Get()
if go.CommandResult() != Rhino.Commands.Result.Success: return
if get_rc == Rhino.Input.GetResult.Number:
return go.Number()
break
print DoSomething()
better to use “mm” or whatever prefix or suffix to be on the safe side

thanks @clement This is exactly what I need.
If I need custom values I can just add them one by one as below.
import Rhino
def NumberWList():
go = Rhino.Input.Custom.GetOption()
go.SetCommandPrompt("Choose or enter a number")
go.AcceptNumber(True, False)
go.AddOption("100mm")
go.AddOption("150mm")
go.AddOption("200mm")
go.Get()
return go.Number()
print (NumberWList())
Rhino Common is just too complicated for me. I much prefer to play with rhinoscriptsyntax. But with examples like this I can learn a bit more.
Hi @dale ,
My code was not working because I am a bad computer programmer and I don’t understand RhinoCommon.
It is a very large library which also works in a different way than rhinoscriptsyntax does.
Thanks to @clement I revised the code to work.
What I really miss with RhinoCommon is simple examples on how to use the classes and methods on https://developer.rhino3d.com/api/rhinocommon/?version=8.x
Examples made out of 2 - 3 lines of code resumed to the essential. Without while loops and if statements required for a proper code. Stripped to the bone indications of working code might help people like me to learn RhinoCommon.
Kind regards
@clement , @dale I need your help again.
On my above script, for NumberWList() how do I add one more variable with go.AddOption(“Session_variable”) that remembers the value for an entire Rhino session.
I should still have the option list 100mm, 150mm, 200mm followed by Session_variable.
When I click on it, I should have the possibility to input a Number.
This Number will be the same for the whole session, unless, changed again.
Thank you again for detailing this topic of Rhino.Input.
Hi @Bogdan_Chipara, try if below helps:
import Rhino
import scriptcontext as sc
def DoSomething():
go = Rhino.Input.Custom.GetOption()
go.SetCommandPrompt("Choose or enter a number")
go.AcceptNumber(True, False)
for n in range(10, 110, 10): go.AddOption("{}{}".format(n, "mm"))
key = "MyCustomNumber"
number = sc.sticky[key] if sc.sticky.has_key(key) else 42
optCustomNumber = Rhino.Input.Custom.OptionInteger(number, True, 1)
go.AddOptionInteger("CustomNumber", optCustomNumber)
while True:
get_rc = go.Get()
if go.CommandResult() != Rhino.Commands.Result.Success: return
if get_rc == Rhino.Input.GetResult.Number:
return go.Number()
if get_rc == Rhino.Input.GetResult.Option:
if go.Option().EnglishName == "CustomNumber":
number = optCustomNumber.CurrentValue
sc.sticky[key] = number
return number
break
print DoSomething()
When you click on the CustomNumber option, you can enter a new number which will be remembered for next run. If you click on it and press Enter, it should return the last used number…

I give up,
There are more lines of code to setup the prompt than the atual code that I want to run…
for this, nice would be, a visual interface to drag-and-drop options and such…
