set parameters in subassembly

[marcelwg75]

I try to set parameters in a subassembly by C#. I followed https://knowledge.autodesk.com/support/autocad-civil-3d/learn-explore/caas/CloudHelp/cloudhelp/2017/...

but when I run the script the parameter is changed if I read the parameters, but the parameter in the subassembly itself it's not changed. How do I change a parameter of a subassembly in a corridor?

CivilDocument doc = CivilApplication.ActiveDocument;

           Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;

           Editor _editor = Application.DocumentManager.MdiActiveDocument.Editor;

           using (Transaction ts = Application.DocumentManager.MdiActiveDocument.

               Database.TransactionManager.StartTransaction())

           {

               string corridorname = "COR_ALM_N_2016";

               //get the corrdior by name:

               ObjectId corridorId = doc.CorridorCollection[corridorname];

               Corridor corridor = ts.GetObject(corridorId, OpenMode.ForRead) as Corridor;

               //get the first applied subassembly in the first assembly in the first BaselineRegion:

              BaselineRegion baselineregion = corridor.Baselines[0].BaselineRegions[0];

               AppliedAssembly appliedassembly = baselineregion.AppliedAssemblies[0];

               AppliedSubassembly appliedsubassembly = appliedassembly.GetAppliedSubassemblies()[0];

               var adds = appliedassembly.GetAppliedSubassemblies();

               ed.WriteMessage("\nAantal subassemblies {0}\n", adds.Count);

               //get parameter key names:

               foreach (IAppliedSubassemblyParam parama in appliedsubassembly.Parameters)

               { ed.WriteMessage("\nParameter key name: {0} & {1} & {2}\n", parama.KeyName, parama.ValueAsObject, parama.ValueType); }

               foreach (var p in appliedsubassembly.Parameters)

               {

                   _editor.WriteMessage("Parameter information: name: {0}, value type: {1}\n", p.KeyName, p.ValueType);

                   Object vobj = p.ValueAsObject;

                   if (p.ValueType == typeof(System.String))

                   { _editor.WriteMessage("Parameter string value: {0}\n", (String)vobj); }

                   else if (p.ValueType == typeof(System.Double))

                   { _editor.WriteMessage("Parameter double value: {0}\n", (Double)vobj); }

                   else if (p.ValueType == typeof(System.Int32))

                   { _editor.WriteMessage("Parameter int32 value: {0}\n", (Int32)vobj); }

                   else if (p.ValueType == typeof(System.Boolean))

                   { _editor.WriteMessage("Parameter bool value: { 0}\n", (Boolean)vobj); }

                   // we should never get here:

                   else { _editor.WriteMessage("Unexpected type.\n"); }

               }

               // Check whether a parameter exists

               bool result = appliedsubassembly.Contains("Bteen");

               // Change a parameter’s value

               AppliedSubassemblyParam<double> param = appliedsubassembly.GetParameter<double>("Bteen");

               ed.WriteMessage("\nValue before {0}m dik {1}\n", param.KeyName, param.Value);

               param.Value = 4.0;

               appliedsubassembly.GetParameter<double>("Bteen").Value = 4.0;

               ed.WriteMessage("\nValue after {0}m dik {1}\n", param.KeyName, param.Value);

           }

Did you commit your transaction? I don't see that happening in your example code.

PS - Using the Insert Code button or the <code> tag when inserting code makes it much easier to read.

I think I solved it. With the code before I changed the parameter of a single APPLIED subassembly, that is one section on the baseline. And only the "value" and not the "designvalue" (thanks to SNOOP!).

This works for me (found it on
