Grasshopper

algorithmic modeling for Rhino

How to use rhino commands or grasshopper components in Python?

Hi,

Sometimes I have no idea which library I should import into python to use some commands in rhino. I tried to import Rhino library and Grasshopper library but I didn't find such functions or any similar ones. For example, I want to add an arrowhead to a curve. In rhino I can directly use "arrowhead" command and select a curve to do this. But I don't know how to realize this in python. And, in grasshopper, I can use "EvaluateLength" component while I don't know how to call this function in python.

So, what I mean is how to convert these rhino and grasshopper things to python.

使用蚂蚱组件在Python，你可以导入ghpythonlib.components https://stevebaer.wordpress.com/使用Python的犀牛命令，你可以RhinoScript语法或进口犀牛等

十分感谢，你解决了我的问题。

这个箭头的问题我是在grasshopper 的python里尝试的，结果用rs.CurveArrows发现返回值只是一个整数。没想到要在rhino 的python里用才有箭头。
