Revit二次开发之“取得元素相交点IntersectionResultArray通过LocationCurve.Intersect()”

1.取得元素的曲线，比如风管

LocationCurve元素曲线

LocationCurve curve = duct.Location as LocationCurve;

取得可以根据曲线确定位置的元素的曲线。

2.根据曲线取得交点

IntersectionResultArray交点数组

SetComparisonResult枚举，判断相交类型

SetComparisonResult result = curve1.Intersect(curve2,out intersectionResultArray);

if(SetComparisonResult.Disjoint != result)//相交

{

    XYZ xyz = intersectionResultArray.get_Item(0).XYZPoint;

｝

3.选取一个元素，可以得到选取点坐标。

reference = sel.PickObject(ObjectType.Element, ductSelectionFilter, "选择第一个风管");

Duct duct = doc.GetElement(myReference) as Duct;

XYZ xyz = reference.GlobalPoint;
