厉害！！！！！！ (vlax-curve-getClosestPointToProjection (vlax-ename->vla-object (car(entsel)))(getpoint) '(0.0 0.0 1.0) t)在将曲线投影到平面上之后，返回曲线上的最近点（在 WCS 上）
(vlax-curve-getClosestPointToProjection curve-objgivenPnt normal )
说明1）参数 curve-obj 为要测量的 VLA 对象。2）参数 givenPnt 为WCS 中的点，在曲线上寻找该点的最近点。3）参数 normal 为WCS 中的法线矢量，指定投影平面。4）参数 extend 若指定该参数且其值不为 nil，vlax-curve-getClosestPointToProjection 在搜索最近点时扩展曲线。5）vlax-curve-getClosestPointToProjection 先将曲线投影到由 givenPnt 和 normal 定义的平面上，后在该平面上计算距 givenPnt 最近的点。最后，vlax-curve-getClosestPointToProjection 将结果点重新投影到原来的曲线上，并返回投影后的点。返回值：若成功，则返回表示曲线上一点的三维点表，否则返回 nil
