Python: Deconstruct a plane into its component parts

Hello everyone !

I'm completely  new in coding and i'm trying to make an iterative 3D tree with python but i'm blocked here:

import rhinoscriptsyntax as rs

line = rs.GetObject("pick line")
ang = rs.GetReal("type angle",35.0)
ang1 = rs.GetReal("type angle",120.0)
scale = rs.GetReal("type angle",0.9)

startPt = rs.CurveStartPoint(line)
endPt = rs.CurveEndPoint(line)
vec = rs.VectorCreate(endPt, startPt)
baseP = rs.PlaneFromNormal (startPt, vec)

print baseP

it returns me: Origin=4,2,0 XAxis=1,0,0, YAxis=0,1,0, ZAxis=0,0,1

After that i want to rotate the "vec" vector with the VectorRotate command and give the ZAxis value to it. How can i retrieve the ZAxis from the BaseP ??

Thanks and if someone is a very big newbee like me in coding, watch the EncodedMatters tutorials from Ezio Blasetti, there are really good !

Hi Ivo,

It's because I am too lazy to look at the whole code.
You should replace the:

    allGenerations.extend(newGeneration)

with:

    allGenerations.extend(newPoints)

The same goes for the upper tree component.

Check the attached file for "a" and "b" points, lines output.
If dataTrees confuse you (allLines, allGenerations) check this topic.

Thank you very much Djordje for taking of your time to help me !!

It's very tricky to understand how to proceed !! Thanks again !
