Automation by discipline
| Discipline | Automation examples |
|---|---|
| HVAC | Duct and pipe sizing, diffuser placement by room airflow, equipment schedules |
| Electrical | Lighting layouts, circuiting, panel schedules, cable tray fill, load reports |
| Plumbing | Fixture unit calculations, pipe sizing, riser diagrams |
| Fire protection | Sprinkler placement by coverage rules, hydraulic data export |
| All disciplines | Tagging, sheet creation, view setup, parameter filling, QA checks |
Documentation automation
Documentation can take a large share of MEP project hours. Revit API tools can:
- Create sheets and place views for every level and discipline.
- Apply view templates, filters and scope boxes consistently.
- Tag all ducts, pipes, equipment and fixtures with collision-aware placement.
- Renumber sheets, views and equipment by rules.
- Export sheets to PDF and DWG with correct naming for transmittals.
Coordination and clash preparation
Automation prepares models for coordination: checking for missing systems, disconnected elements, incorrect insulation and clearance zones before clash detection in Navisworks, reducing noise in clash reports.
From design to fabrication
Converting design models into fabrication-ready parts, spool drawings and cut lists can be partly automated, including numbering, hanger placement and export to fabrication software.
Example: placing tags in Revit (C#)
var ducts = new FilteredElementCollector(doc, view.Id)
.OfCategory(BuiltInCategory.OST_DuctCurves)
.WhereElementIsNotElementType();
using (var t = new Transaction(doc, "Tag ducts"))
{
t.Start();
foreach (Element d in ducts)
{
var mid = ((LocationCurve)d.Location).Curve.Evaluate(0.5, true);
IndependentTag.Create(doc, view.Id, new Reference(d), false,
TagMode.TM_ADDBY_CATEGORY, TagOrientation.Horizontal, mid);
}
t.Commit();
}In MEP, automation turns days of tagging and sheet setup into minutes.
AutoCAD MEP workflows
Many firms still use AutoCAD MEP for 2D and schematic work. Automation there covers schematic generation, equipment tagging, schedules and layer standards.
