在项目中后台创建拉伸实体，请问出现这种异常怎么解决呢

就是没给事务吧

新建一个事务，把创建草图，创建拉伸部分放进去。

又出现了这样的异常：Starting a new transaction is not permitted. It could be because another transaction already started and has not been completed yet, or the document is in a state in which it cannot start a new transaction,这是为什么呢？

还是事务的问题啊，你加的事务放在哪里了？

这是我加的事务：
internal SketchPlane CreateSketchPlane(XYZ normal, XYZ origin)
   {
         using (Transaction tr = new Transaction(_familyDoc))
         {
            tr.Start("CreateSketchPlane");
            Plane geometryPlane = _app.Create.NewPlane(normal, origin);
            if (geometryPlane == null)
            {
               return null;
            }
            SketchPlane plane = SketchPlane.Create(_familyDoc, geometryPlane);

            if (plane == null)
            {
               return null;
            }
            tr.Commit();
            return plane;
         }
   }

//创建拉伸实体
   public void CreateExtrusion1(FamilyItemFactory familyCreator)
   {
         using (Transaction tr = new Transaction(_familyDoc))
         {
            tr.Start("CreateExtrusion");
            CurveArrArray curveArrArray = CreateExtrusionProfile();
            SketchPlane sketchPlane = CreateSketchPlane(XYZ.BasisZ, XYZ.Zero);
            Extrusion rectExtrusion = familyCreator.NewExtrusion(true, curveArrArray, sketchPlane, 10);
            XYZ transPoint1 = new XYZ(-16, 0, 0);

谢谢你，刚才的异常解决了，但是在这句代码：
Family newFamily = familyDoc.LoadFamily(doc)
出现了异常：The document must not be modifiable before calling LoadFamily. Any open transaction must be closed prior the call.
请问这怎么处理呢

如果用Add-In Manage(Manual Mode)这个模式运行代码，还是原来的问题：The document must not be modifiable before calling LoadFamily. Any open transaction must be closed prior the call.

昨天晚上给你调试了一下，有这么几个问题，第一，载入族时不需要加事务，我看了下，开始搞错了，它默认就有个事务所以不用加，所以第一，要把载入族时事务取消。
第二，这个解决后还有个问题，你在创建族实例之前要先将类型激活
在 FamilyInstance fInstance = creationDoc.NewFamilyInstance(new XYZ(0, 0, 0), fs, StructuralType.NonStructural);之前，加上一句fs.Activate();这样应该就能达到你要的效果。

ps：下次提问最好能够用编译器上的截图，加代码。。这样比较好看
