python中MakeSketchTransform(...)的用法

loveblue

MakeSketchTransform(...)
的用法不理解参数的意思，哪位能给解释一下。以下为例：

t = p.MakeSketchTransform(sketchPlane=f.findAt(coordinates=(69.150002, 20.0,
    20.0)), sketchUpEdge=e1.findAt(coordinates=(79.15, 22.5, 20.0)),
    sketchPlaneSide=SIDE1, origin=(39.575, 15.0, 20.0))


This method creates a Transform object. A Transform object is a 4x3 matrix of Floats that represents the transformation from sketch coordinates to part coordinates.
Required argument
sketchPlane
A Datum plane object or a planar Face object specifying the sketch plane.
Optional arguments

origin

A sequence of Floats specifying the X-, Y-, and Z-coordinates that will be used as the origin of the sketch. The default value is computed as the centroid of the face.

sketchOrientation

A SymbolicConstant specifying the orientation of sketchUpEdge on the sketch. Possible values are RIGHT, LEFT, TOP, and BOTTOM. The default value is RIGHT.

铁道科学

MakeSketchTransform是abquas中python模块的命令，不是python自身的。
从意思上看其功能是从草图坐标转换到零件图坐标。没用过abquas，其他的不好说。
