前言

这个例子介绍了 Revit 中的一个实体几何裁剪。

内容

这个例子介绍如何使用 SolidSolidCutUtils 的接口来做几何裁剪以及取消几何裁剪。内容相对来说非常简单。

namespace Autodesk.Revit.DB
{
    public static class SolidSolidCutUtils
    {
        public static void AddCutBetweenSolids(Document document, Element solidToBeCut, Element cuttingSolid, bool splitFacesOfCuttingSolid);
        public static void AddCutBetweenSolids(Document document, Element solidToBeCut, Element cuttingSolid);
        public static bool CanElementCutElement(Element cuttingElement, Element cutElement, out CutFailureReason reason);
        public static bool CutExistsBetweenElements(Element first, Element second, out bool firstCutsSecond);
        public static ICollection<ElementId> GetCuttingSolids(Element element);
        public static ICollection<ElementId> GetSolidsBeingCut(Element element);
        public static bool IsAllowedForSolidCut(Element element);
        public static bool IsElementFromAppropriateContext(Element element);
        public static void RemoveCutBetweenSolids(Document document, Element first, Element second);
        public static void SplitFacesOfCuttingSolid(Element first, Element second, bool split);
    }
}

Cut 命令的核心逻辑

// 获取要操作的元素
Element solidToBeCut = activeDoc.GetElement(new ElementId(solidToBeCutElementId));
Element cuttingSolid = activeDoc.GetElement(new ElementId(cuttingSolidElementId));
// 判断能否进行裁剪
CutFailureReason cutFailureReason = new CutFailureReason();
if (SolidSolidCutUtils.CanElementCutElement(cuttingSolid, solidToBeCut, out cutFailureReason)){
   // 进行裁剪的操作
   SolidSolidCutUtils.AddCutBetweenSolids(activeDoc, solidToBeCut, cuttingSolid);
}

UnCut 命令的核心逻辑

// 获取要操作的元素
Element solidToBeCut = activeDoc.GetElement(new ElementId(solidToBeCutElementId));
Element cuttingSolid = activeDoc.GetElement(new ElementId(cuttingSolidElementId));
// 取消裁剪关系
SolidSolidCutUtils.RemoveCutBetweenSolids(activeDoc, solidToBeCut, cuttingSolid);
