Autodesk Revit插件崩溃

Question

我正在为Autodesk Revit 2014开发一个插件，将房间几何学转换为概念群体。但是当我运行这个脚本时，revit会完全关闭。我已经隔离了导致崩溃的代码：

Extrusion m_Extrusion = m_FamDoc.FamilyCreate.NewExtrusion(true, m_CurveArArray, m_SketchPlane, 8);

而修改日志显示了这个错误：

n:\build\2014_ship_x64_inst_20130308_1515\source\revit\revitui\modscope\ModScope.cpp的第571行:检测到未冻结的选择变化。

有人知道我使用挤压命令有什么问题吗？还是在Revit里有什么？

提前谢谢。

Answer 1

完全冻结是很奇怪的..。它可能与您的代码相关(在NewExtrusion调用之前)

实际上，这个方法有一个完整的示例，请参阅github：ColumnRectangle.cs上的这个文件中的ColumnRectangle.cs方法(第170行)：

// ==========================================
    //   (1) create a simple solid by extrusion
    // ==========================================
    Extrusion createSolid()
    {
      //
      // (1) define a simple rectangular profile
      //
      //  3     2
      //   +---+
      //   |   | d    h = height
      //   +---+
      //  0     1
      //  4  w
      //
      CurveArrArray pProfile = createProfileRectangle();
      //
      // (2) create a sketch plane
      //
      // we need to know the template. If you look at the template (Metric Column.rft) and "Front" view,
      // you will see "Reference Plane" at "Lower Ref. Level". We are going to create an extrusion there.
      // findElement() is a helper function that find an element of the given type and name.  see below.
      //
      ReferencePlane pRefPlane = findElement(typeof(ReferencePlane), "Reference Plane") as ReferencePlane;
      //SketchPlane pSketchPlane = _doc.FamilyCreate.NewSketchPlane( pRefPlane.Plane ); // 2013
      SketchPlane pSketchPlane = SketchPlane.Create( _doc, pRefPlane.Plane ); // 2014

      // (3) height of the extrusion
      //
      // once again, you will need to know your template. unlike UI, the alightment will not adjust the geometry.
      // You will need to have the exact location in order to set alignment.
      // Here we hard code for simplicity. 4000 is the distance between Lower and Upper Ref. Level.
      // as an exercise, try changing those values and see how it behaves.
      //
      double dHeight = mmToFeet(4000.0);

      // (4) create an extrusion here. at this point. just an box, nothing else.
      //
      bool bIsSolid = true;
      return _doc.FamilyCreate.NewExtrusion(bIsSolid, pProfile, pSketchPlane, dHeight);
    }

您是否为此创建了事务？类似的东西:使用(Transaction trans =新事务(doc，"Extrude")) { trans.Start()；Extrude m_extrusion =m_FamDoc.FamilyCreate.NewExtrusion.trans.Commit()；}

通过定义任何类型的Array，我的代码中也出现了同样的问题。经过几周的大搜索，我什么也没有发现，但我意识到我使用了点网框架5.0版本，当我把它改为点网框架4.8时，一切都好了。
