犀牛脚本插件-获取选择对象长度-Python-几何对象长度-rhino脚本

1.程序算法

  犀牛软件是一款专业的三维设计软件。简单实用方便，在三维矢量领域有着广泛的用途，开发拓展这款软件的插件，可以方便设计师摆脱一些繁重的重复劳动，有着现实的需求。作者整理了一个python开发的脚本，功能是获取选择对象的长度，作为范例，源代码如下：

import rhinoscriptsyntax as rs

def CurveLength():
    "Calculate the length of one or more curves"
    # Get the curve objects
    arrObjects = rs.GetObjects("Select Objects", rs.filter.curve, True, True)
    if( arrObjects==None ): return
    rs.UnselectObjects(arrObjects)

    length = 0.0
    count  = 0
    for object in arrObjects:
        if rs.IsCurve(object):
            #Get the curve length
            length += rs.CurveLength(object)
            count += 1
    
    if (count>0):
        print "Curves selected:", count, " Total Length:", length
    
# Check to see if this file is being executed as the "main" python
# script instead of being used as a module by some other python script
# This allows us to use the module which ever way we want.
if( __name__ == "__main__" ):
    CurveLength()

  合理的脚本代码可以有效的提高工作效率，减少重复劳动。
