[VBA函数]：请教：vba 的多义线的offset方法如何用？

vba中的多义线偏移时，对于同样的参数有的图形向外偏移，有的图形向内偏移，为什么？如何判断到底是向外偏移，还是向内偏移？

Distance

Double; input-only
The distance to offset the object. The offset can be a positive or negative number, but it cannot equal zero. If the offset is negative, this is interpreted as being an offset to make a "smaller" curve (that is, for an arc it would offset to a radius that is "Distance less" than the starting curve's radius). If "smaller" has no meaning, then it would offset in the direction of smaller X, Y, and Z WCS coordinates.
