Profile, Profile View, and LabelSetId #

When you create a Profile via Profile.Create API, you need to specify a ProfileSetId, so how can you obtain the ProfileSetId from the code?

This could be important if you are creating an Offset Profile, and you want it to have the same LabelSetId as its parent Profile.

The answer is that you can’t, because there is not such thing as the ProfileSetId for a Profile.

All you have is that you have a ProfileSet for a Profile in a Profile View. Yes, a ProfileSet ( and hence, ProfileSetId) is depending on both the Profile and Profile View.

Since a Profile View can have multiple Profiles, you will need to set their individual LabelSet in the Profile View Properties, as shown in the following screenshot:

How to obtain the LabelSetId for a Profile in a Profile View? #

To obtain the LabelSetId for a Profile in a Profile View, you will need to pass in both the Profile View ObjectId and Profile ObjectId. Here’s the code that you can use to do this.

private static void Transact(Action<Transaction> action)
{
    var doc = Application.DocumentManager.MdiActiveDocument;
    using var tr = doc.TransactionManager.StartTransaction();
    action(tr);
    tr.Commit();
}

public static T GetObject<T>(this Transaction ts, ObjectId objectId, OpenMode openMode = OpenMode.ForRead)
    where T : DBObject
{
    return ts.GetObject(objectId, openMode) as T;
}

[CommandMethod(nameof(ReadProfileLabelSets))]
public void ReadProfileLabelSets()
{
    Transact(ReadProfileLabelSetMethod);
}

private void ReadProfileLabelSetMethod(Transaction ts)
{
    var alignmentIds = CivilApplication.ActiveDocument.GetAlignmentIds();
    var lblgrpClass = RXObject.GetClass(typeof(ProfileLabelGroup));

    foreach (ObjectId alignmentId in alignmentIds)
    {
        var alignment = ts.GetObject<Alignment>(alignmentId);
        var profileIds = alignment.GetProfileIds();

        foreach (ObjectId profileId in profileIds)
        {
            var profileViewIds = alignment.GetProfileViewIds();
            foreach (ObjectId profileViewId in profileViewIds)
            {
                var allPointLabelGroup = ProfileHorizontalGeometryPointLabelGroup.GetAvailableLabelGroupIds(profileViewId, profileId);  
                var lblgrpIds = ProfileLabelGroup.GetAvailableLabelGroupIds(lblgrpClass, profileViewId, profileId, true);
            }
        }
    }
}

So generally, you can use the GetAvailableLabelGroupIds static method to get the available LabelSets for Profiles in Profile View. So the Count above will not be 0 if the LabelSet is properly assigned.
