Question

我想通过IronPython从Curve.Trim(CurveEnd, Double) API调用RhinoCommon方法。我怎样才能确保我没有获得Curve.Trim(Double, Double)的重载？

crv.Trim(geo.CurveEnd.End, 8.8)
    #raised: Message: expected float, got CurveEnd

注意：如果您想自己尝试一下，则需要安装trial version of Rhino。它包括一个Python编辑器。

编辑/添加： Jeff提到的.Overloads属性也不起作用。用于测试的代码段：

import rhinoscriptsyntax as rs
import Rhino.Geometry as geo
import System

# first draw a curve longer than 8.8 units
crvO = rs.GetObject() # to pick that curve on the 3d GUI screen 
crv = rs.coercecurve(crvO)  # to get Rhino.Geometry.Curve

# these both don't work:
crv.Trim(geo.CurveEnd.End, 8.8) 
    #Message: expected float, got CurveEnd

crv.Trim.Overloads[geo.CurveEnd, System.Double](geo.CurveEnd.End, 8.8) 
    #Message: Trim() takes at least 2147483647 arguments (2 given)

rhinscriptsyntax是一个基于RhinoCommon

的Rhino命名空间的库

Answer 1

使用.Overloads属性访问方法的重载：

csv.Trim.Overloads[CurveEnd, float](geo.CurveEnd.End, 8.8)

The docs.

Answer 2

我迟到了。但是此代码有效（超出覆盖范围）。

import rhinoscriptsyntax as rs
import Rhino
import scriptcontext as sc
import System

crv_id = rs.GetObject()
crv = rs.coercecurve(crv_id)
trimmed = crv.Trim(Rhino.Geometry.CurveEnd.End, 4)
sc.doc.Objects.Replace(crv_id, trimmed)
sc.doc.Views.Redraw()

从Ironpython调用重载方法
