自适应族被广大的Revit用户喻为Revit特强大的宝剑之一。关于自适应族的特性请大家看Revit的相关文档。
Revit同时也开放了API来创建自适应构件族,也可以用API来生成自适应构件对象。
Revit提供了AdaptiveComponentFamilyUtils类来处理与创建族相关的功能,提供了10多个方法。具体请看RevitAPI.chm中的说明。
下面列出了如何创建一个自适应构件族的代码。 (摘自RevitAPI.chm)
自适应族的创建于普通族很不一样,可以从代码了解创建步骤和用到的方法。 private void CreateAdaptiveComponentFamily(Document document) { // check if this family is an Adaptive Component family if (!(AdaptiveComponentFamilyUtils.IsAdaptiveComponentFamily(document.OwnerFamily))) return; Transaction transaction = new Transaction(document); ; int placementCtr = 1; ReferencePointArray refPointArray = new ReferencePointArray(); for (int i = 0; i < 10; i++) { transaction.SetName("Point" + i); transaction.Start(); ReferencePoint referencePoint = document.FamilyCreate.NewReferencePoint(new XYZ(i, 0, 0)); if (i % 2 == 0) // Even-numbered reference points will be Placement Points { AdaptiveComponentFamilyUtils.MakeAdaptivePoint(document, referencePoint.Id, AdaptivePointType.PlacementPoint); transaction.Commit(); AdaptiveComponentFamilyUtils.SetPlacementNumber(document, referencePoint.Id, placementCtr); placementCtr++; } else // Odd-numbered points will be Shape Handle Points { AdaptiveComponentFamilyUtils.MakeAdaptivePoint(document, referencePoint.Id, AdaptivePointType.ShapeHandlePoint); transaction.Commit(); } refPointArray.Append(referencePoint); } // Create a curve running through all Reference Points transaction.SetName("Curve"); transaction.Start(); CurveByPoints curve = document.FamilyCreate.NewCurveByPoints(refPointArray); transaction.Commit(); } 如何编程创建自适应构件对象? http://blog.csdn.net/joexiongjin/article/details/8476184在Revit里面创建普通族实例大家不陌生,用NewFamilyInstance函数即可。这个函数有10来个重载形式,可以创建各种族实例。
在有自适应构件的模型里,我们用RevitLookup查看自适应构件的Location属性为空。(普通族实例的Location属性不会为空,或是一个LocationPoint,或者为LocationLine)。这个开发者带来困惑,我们如何编程创建自适应构件的实例呢?
解决:
Revit给自适应构件提供了另一个类来生成自适应族,以及生成自适应构件对象。
就如何生成自适应族,我写了一篇相关博文,
这里说些如何创建自适应构件对象。AdaptiveComponentInstanceUtils 类提供了10个方法用于创建构件。每一个方法的说明请看RevitAPI.chm文件(Revit2012 以上)
下面的代码演示了如何创建自适应构件实例。
先创建一个对象,然后为每一个点设置坐标。 private void CreateAdaptiveComponentInstance(Document document, FamilySymbol symbol) { // Create a new instance of an adaptive component family FamilyInstance instance = AdaptiveComponentInstanceUtils.CreateAdaptiveComponentInstance(document, symbol); // Get the placement points of this instance IList<ElementId> placePointIds = new List<ElementId>(); placePointIds = AdaptiveComponentInstanceUtils.GetInstancePlacementPointElementRefIds(instance); double x = 0; // Set the position of each placement point foreach (ElementId id in placePointIds) { ReferencePoint point = document.GetElement(id) as ReferencePoint; point.Position = new Autodesk.Revit.DB.XYZ(10*x, 10*Math.Cos(x), 0); x += Math.PI/6; } } revit自适应点的解释 http://wenku.baidu.com/link?url=6kxYBwx09Y_O9mpm5IRUiCKZyS3HG3_hpXhThvXO0llLC-8eb4i2odAEGL9aTyied9lIDxAvMguz5i3C9wbzIdvW_f0tTPUw3iN_lddA4wK
