该代码实现了一个计算两个面之间投影距离的方法。通过创建工作部件中的测量距离构建器设置投影方向为指定向量并指定两个测量面对象。使用最小投影距离算法创建测量对象最终返回两个面之间的投影距离值。计算完成后销毁测量构建器以释放资源。该方法适用于需要获取三维空间中面与面之间沿特定方向投影距离的场景。public double ProjectionDistance(Face Disface1, Vector3d DisDirection, Face Disface2) { double distance 0.0; MeasureDistanceBuilder measureDistanceBuilder1 workPart.MeasureManager.CreateMeasureDistanceBuilder(null); // 创建投影方向对象 Point3d WcsOrigin new Point3d(0, 0, 0); Direction direction1 workPart.Directions.CreateDirection(WcsOrigin, DisDirection, SmartObject.UpdateOption.AfterModeling); // 设置投影方向 measureDistanceBuilder1.ProjectionVector direction1; // 设置测量面 measureDistanceBuilder1.Object1.Value Disface1; measureDistanceBuilder1.Object2.Value Disface2; // 创建投影距离测量对象 MeasureDistance measureDistance1 workPart.MeasureManager.NewDistance(null, Disface1, Disface2, direction1, MeasureManager.ProjectionType.Minimum); // 获取测量的距离值 distance measureDistance1.Value; measureDistanceBuilder1.Destroy(); return distance; }
