Get value from Grasshopper to Python

Hi!

I know it possible to set a slider in Grasshopper from a Python script (see below, gh.SetSliderValue(" ")), but is it possible to get the output value of the Grasshopper script back to Python?

Regards,

Stijn

import rhinoscriptsyntax
import Rhino

gh = Rhino.RhinoApp.GetPlugInObject("Grasshopper")

#SetSliderValue("GUID",Number)

gh.SetSliderValue("c70bd93b-749b-42d2-aee2-bb5e97cf473d",5)

Hi Stijn,

When you say Python, you mean: RhinoPython editor?
If that is so, then at the end of your ghpython component, you can send the output to sticky dictionary:

a = "someValue"

sc.sticky["ghpython_component2_output"] = a

Then in RhinoPython editor, you can read the value you assigned to the mentioned key:

try:
a = sc.sticky["ghpython_component2_output"]
except:
print "no value has been assigned to \"ghpython_component2_output\" key"

Hi djordje,

Thanks for your reaction, but i'm not sure we are talking about the same thing.

I am not using a ghpython component in Grasshopper, but i loaded the Grasshopper Plugin into RhinoPython editor.

In the link below they manage to automate the sliders, but now I want to load the result from Grasshopper back to RhinoPython.

As far as I have seen at the link below, there's no such method available through Grasshopper RhinoScript. BakeDataInObject could be used to bake the geometry, but anything other than geometry would not be able to be baked.
