Transferring Rhino Python Script over to Grasshopper

the python script in the tutorial relies on creating polylines in the rhino document, and also relies on user input from the command line.

first, we need to supply the inputs in the python script component. rename your inputs (x and y by default) "crvs" and "num." You should also right-click the "crvs" input and select "list access" because the function expects a list of polylines. 

change these two lines (which get the input via the command line):

count = rs.GetInteger("How many iterations would you like to do?", 3)
pl = rs.GetCurveObject("pick a closed curve to crack")

to this: 

count = num

pl = crvs

 

when you use rhinoscripting in gh python, it creates a virtual rhino document in the scriptcontext object. At the end, in order to harvest the geometry from this virtual rhino document, add this line: 

a = scriptcontext.doc.Objects.Geometries

That should get everything working for you in a GH context.
