标题: 求助2.0
（以后我的求助都按n.0的方式来做，1年之后，看自己能求助多少，{:3_53:}）

Dim arrPlane, arrRotated

arrPlane = Rhino.WorldXYPlane

arrRotated = Rhino.RotatePlane(arrPlane, 45.0, arrPlane(3))

Rhino.AddArc arrRotated, 5.0, 45.0

arrPlane(3)这个什么意思啊？怎么突然出现个3？

语法上讲vb的括号有函数和数组元素的意思

这里arrplane应该是个数组啦

RotatePlane
Rotates a plane.

Syntax
Rhino.RotatePlane (arrPlane, dblAngle, arrAxis)

Parameters
arrPlane
Required.  Array.  The plane.  The elements of a plane array are as follows:

Element
Description

0
Required.  The plane's origin (3-D point).

1
Required.  The plane's X axis direction (3-D vector).

2
Required.  The plane's Y axis direction (3-D vector).

3
Optional.  The plane's Z axis direction (3-D vector).

dblAngle
Required.  Number.  The rotation angle in degrees.

arrAxis
Required.  Array.  A non-zero 3-D vector identifying the axis of rotation.

Returns
Array
The plane if successful.  The elements of a plane array are as follows:

Element
Description

0
The plane's origin (3-D point).

1
The plane's X axis direction (3-D vector).

2
The plane's Y axis direction (3-D vector).

3
The plane's Z axis direction (3-D vector).

Null
If not successful, or on error.

Example
Dim arrPlane, arrRotated

arrPlane = ViewCPlane

arrRotated = RotatePlane(arrPlane, 45.0, arrPlane(1))

Rhino.ViewCPlane , arrRotated

帮助里写的很清楚

多谢，刚学不多久，容易把某些概念弄混，现在感觉清楚多了，再谢过
