为什么使用AddPlanarSrf得到的平面无法进行Offset呢

使用AddPlanarSrf得到一个平面，然后进行Offset

import rhinoscriptsyntax as rs
import math

def test1():
    HANDLER_R = 3
    HANDLER_H = 15
    HANDLER_T = 8
    CURVE_DEGREE = 3
   
    P1 = [0, 0, 0]
    P2 = [HANDLER_R, -HANDLER_R, 0]
    P3 = [HANDLER_T, HANDLER_H/2, 0]
    P4 = [HANDLER_R, HANDLER_H+HANDLER_R, 0]
    P5 = [0, HANDLER_H, 0]
    P6 = [0, 0, 0]
   
    curve = rs.AddCurve([P1, P2, P3, P4, P5, P6], CURVE_DEGREE)
    surface = rs.AddPlanarSrf(curve)
    inner_e = rs.OffsetSurface(surface[0], 3, None, False, True)

得到平面surface后偏移，结果inner_e为None，偏移失败，但是在命令行中选择偏移命令就可以成功，百思不得其姐，希望高手解答一下。

rhinoscriptsyntax里面的offset有bug，用rhinoscriptsyntax里面的offset不能偏移剪切过的面啥的，可以调用rhinocommon来解决。。。

import rhinoscriptsyntax as rs
import Rhino.Geometry as rg
import scriptcontext as sc
import math

def test1():
    HANDLER_R = 3
    HANDLER_H = 15
    HANDLER_T = 8
    CURVE_DEGREE = 3

    P1 = [0, 0, 0]
    P2 = [HANDLER_R, -HANDLER_R, 0]
    P3 = [HANDLER_T, HANDLER_H/2, 0]
    P4 = [HANDLER_R, HANDLER_H+HANDLER_R, 0]
    P5 = [0, HANDLER_H, 0]
    P6 = [0, 0, 0]

    curve = rs.AddCurve([P1, P2, P3, P4, P5, P6], CURVE_DEGREE)
    surface = rs.AddPlanarSrf(curve)
    surface = rs.coercebrep(surface)
    face = surface.Faces[0]
    brep = surface.CreateFromOffsetFace(face,3,0.01,False,True)
    sc.doc.Objects.AddBrep(brep)
    sc.doc.Views.Redraw()
    #inner_e = rs.OffsetSurface(surface[0], 3, None, False, True)


test1()


像这样就Ok啦

太感谢了，高手就是高手啊
