Hi guys,

I get this error only by writing this code:

import rhinoscriptsyntax as rs  
import Rhino.Geometry as rg  
sketches = rs.GetObjects(“select sketch”)

Is something to do with Rhino 6?  
Any help? below the copy-pasted error.

## Thanks! Manuel

many of the “get” functions are not in ghpython. you have to switch scope to rhino doc

```auto
from Rhino.RhinoDoc import ActiveDoc as rhdoc
import scriptcontext as sc
sc.doc = rhdoc
# put all your 'get' functions here
# ...
# end of your 'get' functions
sc.doc = ghdoc

```

Make sure you wrap your ‘get’ also in a `if` statement and feed a boolean to run it. otherwise every time this component runs the rhino will prompt for input.

Nooo, and they shouldn’t!

You can **use the variable that comes in from the inputs**. You do NOT need the GetX() functions in GhPython, they are against its philosophy of native Grasshopper integration.

Please read [this documentation page](https://developer.rhino3d.com/guides/rhinopython/ghpython-component/) by Scott.
