API for property set - get automatic properties?
The PropertySet.GetAt() function returns the value of any Property. For instance:
var entPsets = PropertyDataServices.GetPropertySets(ent);
foreach (ObjectId entPset in entPsets)
{
var pSet = (PropertySet)entPset.GetObject(OpenMode.ForRead);
foreach (var name in GetPropDefs(pSet.PropertySetDefinition))
{
var data = pSet.GetAt(pSet.PropertyNameToId(name));
//do what you need with the value in data.
....
}
}
GetPropDefs is just a small helper function to get a list of the PropertyDefintion names in the PSet.
Hi, we don't have a problem getting values but our problem is that we don't know which automatic PropertySets are applied to an entity.
Settings:
One group with 2 definitions.
Applied to a Solid3D.
But code returns only one ObjectId for Length definition.
ObjectIdCollection psdColl = PropertyDataServices.GetPropertySets(entity); // count 1 but entity has 2 definitions
Of course we can use propertySet.GetAt(propertySet.PropertyNameToId("Handle")); but how can we know that this automatic definition was applied to this entity?

Are we confusing PropertySetDefinition, PropertySet, and PropertyDefinition?
Below is a quick example of getting the propertySetDefinition for a given object and then for each property definition print to the command line the property name and if it is automatic property or not.
<CommandMethod("PS_DumpProperties")>
Public Sub CmdPS_DumpProperties()
Dim doc As Document = Application.DocumentManager.MdiActiveDocument
Dim ed As Editor = doc.Editor
Dim db As Database = doc.Database
Dim res As PromptEntityResult = ed.GetEntity(vbCrLf & "Select entity: ")
If res.Status <> PromptStatus.OK Then Exit Sub
Using tr As Transaction = db.TransactionManager.StartTransaction
Dim dbObject As DBObject = tr.GetObject(res.ObjectId, OpenMode.ForRead)
Dim ids As ObjectIdCollection = PropertyDataServices.GetPropertySetDefinitionsUsed(dbObject)
For Each id As ObjectId In ids
Dim propSetDef As PropertySetDefinition = tr.GetObject(id, OpenMode.ForRead)
ed.WriteMessage(vbCrLf & "Property Set Defintion Name: " & propSetDef.Name)
For Each propDef As PropertyDefinition In propSetDef.Definitions
ed.WriteMessage(vbCrLf & "Property Name: " & propDef.Name & " | Is Automatic: " & propDef.Automatic.ToString)
Next
Next
tr.Commit()
End Using
End Sub
I hope that this helps clarify some things.

To clarify your confusion here...there is ONE PropertySet assigned to the entity. That PropertySet has TWO PropertyDefinitions. By using the GetAt function you are getting that PropertyDefinition value assigned to the entity from which you obtained the PropertySet.
