Group Box in SOLIDWORKS Property Manager Page

Group box will be automatically created for all complex types in the data model

public class GroupDataModel
{
    public class DataGroup
    {
        public string Text { get; set; }
    }

    public DataGroup Group { get; set; }
}

SOLIDWORKS doesn't support groups nested into other groups, so all the nested complex types will be added as the groups to the main property manager page.
