返回沿曲线的指定参数值处的点 支持的平台:仅窗口 签名(vlax-curve-getPointAtParam curve-obj param)
返回值类型:列出或无 表示曲线上点的 3D 点(如果成功);否则。nil 例子对于以下示例,假定 指向示例中所示的样条曲线。splineObjvlax-curve-getDistAtParam 获取曲线的起始参数: (setq startSpline (vlax-curve-getStartParam splineObj)) 0.0 获取曲线的结束参数: (setq endSpline (vlax-curve-getEndParam splineObj)) 17.1546 确定曲线中途参数处的点: (vlax-curve-getPointAtParam splineObj ( / (- endspline startspline) 2)) (6.71386 2.82748 0.0) |
