【OPM C#】如何获取管接头方向数据

DgnUtilities.GetInstancesFromDgn("NOZZLE");返回的对象,仅找到位置坐标,关联的“NOZZLE_HAS_PORT”对象也仅有位置坐标,不知道有没有办法可以得到管接头方向数据?

  • 首先检查一下,您是否用Workspace打开的DGN文件,且您的NOZZLE Schema定义中有其它属性。

    可以使用 ecx items dump这个Keyin,然后检查一下生成的xml文件中的NOZZLE和PORT是否有所有的EC属性。

    没有的话应该是要么没有使用正确的工作空间,要么是其他问题导致Schema没有加载上。

    然后可以按照这个思路写段代码调试一下,看能否取出其它属性:

    SDKExamples\ZeroLengthPipesExample

    private void BtnReport_Click(object sender, EventArgs e)
    {
    ECInstanceList pipeInstances = DgnUtilities.GetInstancesFromDgn("PIPE", false);

    if(pipeInstances != null && pipeInstances.Count > 0)
    {
    foreach(IECInstance instance in pipeInstances)
    {
    double length = instance["LENGTH"].DoubleValue;
    if(length < 0.00001)
    {
    string name = GetValue(instance, "NAME");
    string pipeline = GetValue(instance, "LINENUMBER");
    string spec = GetValue(instance, "SPECIFICATION");
    string nominalSize = GetValue(instance, "NOMINAL_DIAMETER");
    string Length = GetValue(instance, "LENGTH");

    ListViewItem item = new ListViewItem(name);
    item.SubItems.Add(pipeline);
    item.SubItems.Add(nominalSize);
    item.SubItems.Add(spec);
    item.SubItems.Add(Length);
    LstPipes.Items.Add(item);
    }
    }
    }
    else
    MessageBox.Show("No pipes found with length zero.", "OpenPlant Modeler SDK Examples", MessageBoxButtons.OK, MessageBoxIcon.Information);
    }

    方向:

    PORT有DIRECTION_X Y Z属性

  • 感谢解答,Schema应该没错,看数据,我之前认为Direction_X这些不是方向数据,因为数值对不上,见下图。

    右视图:

        显示方向向量为(-1,0,0)

    俯视图:

    方向数据不对,这个x方向应该为0,另外两个方向不为0才对啊?

    是否需要通过这个数据+元素的矩阵二次计算?

  • 那直接用它的矩阵吧

  • OK,我再试试,另外突然发现个小问题,就不另开一帖了。

    DgnUtilities.GetInstanceByGuid()应该怎么使用?下面的GUID是附件图纸里设备的GUID。

    DgnUtilities.GetInstanceByGuid("66449e9d-f3e4-45c2-a8ad-5e68f20c57a9");//返回null
    DgnUtilities.GetInstancesFromDGNByProperty("GUID", "66449e9d-f3e4-45c2-a8ad-5e68f20c57a9");//正常返回,集合数量为1

  • 这个API有点问题,预计Update 9修复,我做的一个临时替代办法:

                    //Create Pipe.

                    PipeComponentData pipe1Data = new PipeComponentData(specification, nominalDiameter);

                    pipe1Data.SetProperty("LENGTH", length.ToString());

                    PipeComponent pipe1 = new PipeComponent(origin, pipe1Data, 0, DrawingView.ViewTop, true);

                    pipe1.Create();

                    ComponentPropertiesGetter pGetter = new ComponentPropertiesGetter(pipe1);

     

                    // Yes, it is the GUID of the newly created PIPE, I have verified it with the result of "ecx items dump"

                    string guid = pGetter.GetPropertyValue("GUID");

                    Debug.WriteLine(guid);

     

                    ECInstanceList plantInstanceList = DgnUtilities.GetInstancesFromDgn("PLANT_BASE_OBJECT", true);

                    foreach (IECInstance plantInstance in plantInstanceList)

                        {

                        if (plantInstance["GUID"].StringValue == guid)

                            {

                            IDgnECInstance dgnInstance = plantInstance as IDgnECInstance;

                            Element element = dgnInstance.Element;

                            Debug.WriteLine(element.ElementId);

                            Debug.WriteLine("We found it!"); // Indeed, we found it.

                           // You can operate on the element immediately;

                     // or just cache its “Plant Object Instance GUID” somewhere and operate on them later in a batch.

                            }

                        }
