Getting PropertySetDefinition Value of an object

lumoric — Thu, 20 Oct 2022 06:22:12 GMT

Hi,

How to get an actual Value of a object's PropertySetDefinition?

I thought it is this method:

GetValue(int propertyId, Autodesk.AutoCAD.DatabaseServices.ObjectId id, Autodesk.AutoCAD.DatabaseServices.ObjectIdCollection blockRefPath)

but it is causing Civil3d to crash with fatal error "unhandled access violation reading 0x0000 exception at autocad"

Here is my code so far:

[CommandMethod("PropSets")] public void PropSets() { Editor ed = Application.DocumentManager.MdiActiveDocument.Editor; CivilDocument doc = CivilApplication.ActiveDocument; // select a TIN surface PromptEntityOptions opSelSurface = new PromptEntityOptions("\nSelect a TIN Surface: "); opSelSurface.SetRejectMessage("\nOnly TIN Surface is allowed"); opSelSurface.AddAllowedClass(typeof(TinSurface), true); opSelSurface.AppendKeywordsToMessage = true; PromptEntityResult resSelSurface = ed.GetEntity(opSelSurface); ObjectId surfaceId = resSelSurface.ObjectId; Database db = Application.DocumentManager.MdiActiveDocument.Database; using (Transaction transsrc=db.TransactionManager.StartTransaction()) { TinSurface surface = transSrc.GetObject(surfaceId, OpenMode.ForWrite) as TinSurface; ObjectIdCollection plinePropSetDefs = PropertyDataServices.GetPropertySetDefinitionsUsed(surface); foreach (ObjectId plinePropSetDef in plinePropSetDefs) { var prop = transSrc.GetObject(plinePropSetDef, OpenMode.ForWrite) as PropertySetDefinition; foreach(PropertyDefinition propDef in prop.Definitions) { ObjectIdCollection idsDummy = new ObjectIdCollection(); string val = propDef.Description; try { string propsetdef = prop.GetValue(propDef.Id, surfaceId, plinePropSetDefs).ToString(); Application.ShowAlertDialog("Surface property set def: " + propDef.Name.ToString() + propsetdef); } catch (Exception ex) { Application.ShowAlertDialog(ex.Message); } } } } }

HI @lumoric

Because he gives a NULL when he REEGING OBJECTID

as in Image

TRY :

[CommandMethod("TESTPropSets")] public void PropSets() { Editor ed = Application.DocumentManager.MdiActiveDocument.Editor; CivilDocument doc = CivilApplication.ActiveDocument; // select a TIN surface PromptEntityOptions opSelSurface = new PromptEntityOptions("\nSelect a TIN Surface: "); opSelSurface.SetRejectMessage("\nOnly TIN Surface is allowed"); opSelSurface.AddAllowedClass(typeof(TinSurface), true); opSelSurface.AppendKeywordsToMessage = true; PromptEntityResult resSelSurface = ed.GetEntity(opSelSurface); ObjectId surfaceId = resSelSurface.ObjectId; Database db = Application.DocumentManager.MdiActiveDocument.Database; using (Transaction transsrc=db.TransactionManager.StartTransaction()) { TinSurface surface = transsrc.GetObject(surfaceId, OpenMode.ForWrite) as TinSurface; ObjectIdCollection plinePropSetDefs = PropertyDataServices.GetPropertySetDefinitionsUsed(surface); foreach (ObjectId plinePropSetDef in plinePropSetDefs) { var prop = transsrc.GetObject(plinePropSetDef, OpenMode.ForWrite) as PropertySetDefinition; foreach (PropertyDefinition propDef in prop.Definitions) { ObjectIdCollection idsDummy = new ObjectIdCollection(); string val = propDef.Description; try { var propsetdef = prop.GetValue(propDef.Id, surfaceId, plinePropSetDefs); //Application.ShowAlertDialog("Surface property set def: " + propDef.Name.ToString()); } catch (System.Exception ex) { Application.ShowAlertDialog(ex.Message); } } } } }

The following is an example as to how to get the value of the PropertySet

Dim propSetId As ObjectId = PropertyDataServices.GetPropertySet(dbObject, _propertySetDefinitionId) Dim propSet As PropertySet = tr.GetObject(propSetId, OpenMode.ForRead) Dim val As Object = propSet.GetAt(propSet.PropertyNameToId(propertyName))

I hope that this helps!

Just verifying that this can only be done by python?

The OP is writing in C# on the .NET framework. In Hosneyalaa's post they are using Dynamo. And in my example I am writing in VB on the .NET framework. Are you referring to using Python in Dynamo?

Sorry, I meant to ask if it requires code to be written, or if it can be done with modules?

I guess I am not sure what you mean when you say modules. In terms of VB a module is a Static Class, as in a module cannot create instances on an object. I am assuming you are referring to using Python? The code posted in this thread is for creating a DLL file that can be imported through the use of the NETLOAD command. Feel free to start a new thread with your question about Modules and the use of Python. That will help engage others in answering your question.
