Beginner’s Guide to Move Point and Line Elements

This video is an example of moving point and line based Revit elements.  Point based elements such as columns, doors etc. have a point with an XYZ coordinate location.  This can be reassigned with “ElementTransformUtils.MoveElement(document, xyz);”.  Line base elements such as walls, framing etc. have a start and end point.  Begin by creating a “Line” with your new location of start XYZ and end XYZ. Once you have a line you can reassign it to your “element.Curve".

Sample code - Point Base:

          Element e = SelectElement(uidoc, doc);

            FamilyInstance familyInstance = e as FamilyInstance;

            LocationPoint locationPoint = familyInstance.Location as LocationPoint;

            XYZ currentLocation = locationPoint.Point;

            XYZ newLocation = new XYZ(0, 10, 10);

            using (Transaction t = new Transaction(doc, "move"))

            {

                t.Start("move");

                ElementTransformUtils.MoveElement(doc, familyInstance.Id, newLocation);

                t.Commit();

string info = "old " + currentLocation + " new " + newLocation;

                TaskDialog.Show("Revit", info);

            }

Sample code - Line Base:

            Element e = SelectElement(uidoc, doc);

            Wall wall = e as Wall;

            LocationCurve wallLine = wall.Location as LocationCurve;

            XYZ sXYZ = new XYZ(10, 20, 0);

            XYZ eXYZ = new XYZ(20, 20, 0);

            Line newWallLine = Line.CreateBound(sXYZ, eXYZ);

            using (Transaction t = new Transaction(doc, "move"))

            {

                t.Start("move");

                wallLine.Curve = newWallLine;

                t.Commit();

            }
