OPM Formula to catch Name to cell name

Question

Hi Gents 
 I am looking for a method in OPM, when we placed a support location, is possible to catch the support number of the support location to the cell name? e.g. in element properties, 
 Cell Name = Name as shown the illustrated fig below, can you give some tips how can I make it? I know there maybe some function in class editor, it maybe can add some formula/expression. 
 I want the parameter "Cell Name" got the name as in OPM support location attribute automatically. 
 3107.Empty.dgn

You need to do something like below. 
 ScanCriteria* pScanCriteria = mdlScanCriteria_create(); 
 mdlScanCriteria_addSingleElementTypeTest (pScanCriteria, CELL_HEADER_ELM); mdlScanCriteria_setReturnType (pScanCriteria, MSSCANCRIT_RETURN_FILEPOS, FALSE, TRUE); mdlScanCriteria_setRangeTest (pScanCriteria, NULL); //no range test mdlScanCriteria_setModel (pScanCriteria, ACTIVEMODEL); /* loop through all Titel cell elements in file */ do { 
 //once you get a cell name here..you need to use EC Framework APIs to extract the EC data and get the Name of the element. 
 and then use MDL APIs for changing the cell name Property. 
 }

Hi Sir 
 The reason is because I found the model will always show as a name "Cell" in our review model tree, e.g. Navisworks. 
 
 but if I give a name to the cell, the cell name will be shown in the model tree, instead of "Cell". 
 But in this case we have define the cell name manually both in OPM TAG and Element properties. that is double work. 
 So I wondering if I can add some ECexpression etc within Class Editor, to let the Cell Name = TAG. that will be perfect! 
 Do you understand?

Cell Name is a Microstation property and OPM doesnt have control over it because its not available in OPM Schema. But if you try to rename the CellName from Element Info by Double Clicking the name "SP-3" it takes that name into your Cell Name property. So OPM is not doing a good job of reading the actual cell name and putting it on the Microstation Cell Name property. You can fix this by writing an MDL application which will 1) scan every component in the DGN 2) Read Its Name/TAG property 3) Write it on the Cell Name property.

试了一下还是不行，调试时Case Else代码段总是不会执行。 
 Select Case GetCellProperty(Mycell, "SUPPORT_NAME") Case "NotAvailable" Case Else SetCellProperty Mycell, "CellName", GetCellProperty(Mycell, "NAME") End Select
