Batch Rename Views

Data Management Intermediate

Renames all Revit views matching a pattern — apply prefix and format string to enforce BIM naming standards across the entire project at once.

Inputs

prefix — string prepended to each view name
namingFormat — template e.g. \${prefix}_\${level}_\${discipline}
matchPattern — filter string to select target views

Outputs

renamedViews — list of View elements updated
newNames — list of new name strings
errorLog — views that could not be renamed

Standardize all floor-plan view names to 'AR_L01_FloorPlan' in one click before issuing drawings.

Export Room Data to Excel

Data Management Beginner

Collects all placed rooms and exports name, number, area, and department to CSV. Handles multiple levels, converts area units from imperial to metric.

Inputs

outputPath — full file path for CSV
areaUnit — 'sqft' or 'sqm' (default sqm)

Generate room data spreadsheet for MEP consultant showing every room with area in m² by department.

🐍 Python Script Node ▾

# Export Room Data to CSV
import clr, csv
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
from RevitServices.Persistence import DocumentManager

doc = DocumentManager.Instance.CurrentDBDocument
out_path = IN[0]
SQFT_TO_SQM = 0.092903

rooms = FilteredElementCollector(doc)\
        .OfCategory(BuiltInCategory.OST_Rooms).ToElements()

rows = []
for r in rooms:
    if r.Area == 0: continue
    dept = r.LookupParameter("Department")
    rows.append([r.Number, r.Name,
        round(r.Area * SQFT_TO_SQM, 2),
        dept.AsString() if dept else ""])

with open(out_path, "w", newline="") as f:
    csv.writer(f).writerows(rows)
OUT = [out_path, len(rows)]

Place Furniture from Grid

Geometry & Placement Intermediate

Places family instances on a regular rectangular grid defined by origin, X/Y spacing, and count. Supports rotation alignment.

Inputs

originPoint — XYZ origin of the grid in project units
spacingX / spacingY — horizontal and vertical spacing in mm
countX / countY — grid dimensions
familyName + typeName — loadable family to place

Populate an open-plan office with 120 workstation families in a 6×20 grid at 1800×2400mm spacing.

🐍 Python Script Node ▾

# Place Furniture on a Regular Grid
import clr
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
sx, sy = IN[1] / 304.8, IN[2] / 304.8
cx, cy = int(IN[3]), int(IN[4])

sym = next((fs for fs in
      FilteredElementCollector(doc).OfClass(FamilySymbol)
      if fs.Family.Name == IN[5] and fs.Name == IN[6]),None)
level = FilteredElementCollector(doc)\
        .OfClass(Level).FirstElement()

placed = []
TransactionManager.Instance.EnsureInTransaction(doc)
if not sym.IsActive: sym.Activate()
for row in range(cy):
    for col in range(cx):
        pt = XYZ(col * sx, row * sy, 0)
        placed.append(doc.Create.NewFamilyInstance(
            pt, sym, level, Structure.StructuralType.NonStructural))
TransactionManager.Instance.ForceCloseTransaction()
OUT = [placed, len(placed)]

Batch Update Parameters

Data Management Intermediate

Find all elements where a parameter matches a value and replace it with a new value. Supports instance and type parameters for bulk data corrections.

Use Case

Rename all elements with Fire Rating '60 min' to '60 MIN REV2' after the fire consultant issues a revised schedule.

Dynamo BIM Info

Dynamo is an open-source visual programming environment extending Autodesk Revit with algorithmic design and BIM automation. Scripts run in IronPython 2.7 (Dynamo 2.x) or CPython 3 (Dynamo 3.x / Revit 2024+). See AEC Hackathon community for advanced patterns.
