Insert Column

gustavosanmartin — Wed, 12 Apr 2023 14:55:53 GMT

Hi, I'm starting C# programming and I'm trying to run this code to understand how it works. I'm interested in being able to insert columns. Can you help me understand why I can't run it. Thank you so much

#region Creando un pilar Metodo 2 ICollection BatchCreateColumns(Autodesk.Revit.DB.Document document, Level level) { List fiCreationDatas = new List(); ICollection elementSet = null; //Try to get a FamilySymbol FamilySymbol familySymbol = null; FilteredElementCollector collector = new FilteredElementCollector(document); 1ICollection collection = collector.OfClass(typeof(FamilySymbol)).ToElements(); foreach (Element e in collection) { familySymbol = e as FamilySymbol; if (null != familySymbol.Category) { if ("Structural Columns" == familySymbol.Category.Name) { break; } } } if (null != familySymbol) { //Create 10 FamilyInstanceCreationData items for batch creation for (int i = 1; i < 11; i++) { XYZ location = new XYZ(i * 10, 100, 0); FamilyInstanceCreationData fiCreationData = new FamilyInstanceCreationData(location, familySymbol, level, StructuralType.Column); if (null != fiCreationData) { fiCreationDatas.Add(fiCreationData); } } if (fiCreationDatas.Count > 0) { // Create Columns elementSet = document.Create.NewFamilyInstances2(fiCreationDatas); } else { throw new Exception("Batch creation failed."); } } else { throw new Exception("No column types found."); } return elementSet; } #endregion

Welcome to the Revit API! Are you interested in history? Here is a lesson from 13 years ago:

https://thebuildingcoder.typepad.com/blog/2009/02/inserting-a-column.html

I'm afraid one or two things have changed since then.

Before addressing this programmatically, I hope you have tried it out manually in the end user interface to understand the basic BIM principles involved.

Thank you very much for your answer, I have looked at the code that you have provided me and I have been able to arrive at the following. The problem I have is that I can't insert a column and I don't know what the problem could be.

// Obtener el documento actual y la aplicación de Revit UIDocument uidoc = commandData.Application.ActiveUIDocument; Document doc = uidoc.Document; // Seleccionar la ubicación de inserción del pilar //UIDocument uiDoc = new UIDocument(doc); // Pedir al usuario que seleccione un muro Reference wallRef = uidoc.Selection.PickObject(ObjectType.Element, new WallSelectionFilter(), "Selecciona un muro"); // Obtener el muro seleccionado Wall wall = doc.GetElement(wallRef) as Wall; // Obtener el nivel correspondiente al nivelId de un elemento ElementId levelId = wall.LevelId; Level level = doc.GetElement(levelId) as Level; // Imprimir el nombre del nivel (si se encontró) if (level != null) { TaskDialog.Show("Nivel correspondiente", "El nivel correspondiente es: " + level.Name); } else { TaskDialog.Show("Nivel correspondiente", "No se pudo encontrar el nivel correspondiente."); } XYZ columnLocation = uidoc.Selection.PickPoint("Selecciona la ubicación del pilar"); TaskDialog.Show("Revit", "Coordenadas del Pickpoint: " + columnLocation.ToString()); string columnName = "Columnas"; // Definimos el tipo de pilar que queremos insertar FilteredElementCollector columnCollector = new FilteredElementCollector(doc); ElementFilter columnFilter = new ElementClassFilter(typeof(FamilySymbol)); ICollection<Element> columnTypes = columnCollector.WherePasses(columnFilter).ToElements(); FamilySymbol columnSymbol = null; foreach (Element elem in columnTypes) { FamilySymbol sym = elem as FamilySymbol; if (sym != null && sym.Family.Name == columnName) { columnSymbol = sym; break; } } TaskDialog.Show("Revit", "columnSymbol: " + columnSymbol.Family.Name.ToString()); doc.Create.NewFamilyInstance(columnLocation, columnSymbol, level, StructuralType.Column);

You need to use transaction to make changes to a document.

Put your doc.Create.NewFamilyInstance under transaction.

using (Transaction columnInsertTransaction = new Transaction(doc))
{
if (columnInsertTransaction.Start("Insert Column") == TransactionStatus.Started)
{
doc.Create.NewFamilyInstance(columnLocation, columnSymbol, level, StructuralType.Column);

}
columnInsertTransaction.Commit();
}

Thank you very much for your answer, I had solved it this way considering what you mention.

string columnName = "Columnas 6x6"; // Buscar el FamilySymbol correspondiente al tipo de familia de columna que deseas insertar FilteredElementCollector col = new FilteredElementCollector(doc).OfClass(typeof(FamilySymbol)); FamilySymbol columnType = col.FirstOrDefault(e => e.Name.Equals(columnName)) as FamilySymbol; // Verificar que se encontró el FamilySymbol correspondiente if (columnType == null) { TaskDialog.Show("Error", "No se encontró el tipo de familia de columna especificado."); } // Obtener el punto de inserción de la columna mediante el objeto de selección del usuario XYZ insertionPoint = uidoc.Selection.PickPoint(); // Crear una nueva instancia de la columna utilizando el tipo de familia de columna y el punto de inserción seleccionados Transaction transaction = new Transaction(doc, "Insertar columna"); transaction.Start(); FamilyInstance columnInstance = doc.Create.NewFamilyInstance(insertionPoint, columnType, doc.ActiveView.GenLevel, Autodesk.Revit.DB.Structure.StructuralType.Column); transaction.Commit(); // Mostrar un mensaje de confirmación TaskDialog.Show("Columna insertada", "Se insertó una nueva columna en la vista activa."); #endregion
