3dshouse builds custom Revit add-ins (C# / .NET, Revit API) — professional Revit plugin development service — for BIM teams, architecture and engineering firms, and product manufacturers: data automation, batch tools, family and parameter management, and integrations that remove hours of repetitive Revit work every week.
Your add-in is built by the developer of Metasheet for Revit, with an AI-assisted development workflow that keeps quality high and delivery fast — see how we build Revit add-ins with AI.
Revit Add-in Development Pricing

| Complete add-in | Full UI, multi-version support, installer, company deployment, external integrations. Source code included. | from $1,500 | 2–4 weeks |
- Consultation and exact quote are free — describe what you need and you get a fixed quote within 48 hours.
- 50% deposit to start, the rest on delivery. 2–3 revision rounds are included in the agreed scope.
- You own the delivered code. Support for Revit 2022 and newer, multi-version builds available.
What we can build — Custom Revit Add-in Scope
- Data automation: schedules and model data to Excel / Google Sheets and back, bulk parameter editing, model audits.
- Batch tools: sheet and view creation, printing and export (PDF/DWG/IFC) across the whole project in one click.
- Family automation: generate and update families and types from your product catalog or spreadsheets.
- Dynamo to add-in: convert slow, fragile Dynamo scripts into fast, production-ready Revit add-ins, shareable add-ins your whole team can run.
- Integrations: connect Revit to your ERP, pricing database or web service through the Revit API.
Benefits for BIM teams and manufacturers
- Hours of repetitive Revit work become one button.
- Standards are enforced by the tool, not by training documents.
- Manufacturers: your products become Revit families that designers actually place in projects.
Multi-version support, done right
Supporting several Revit releases from one add-in is the part most teams underestimate. Revit 2025 and 2026 moved from the old .NET Framework 4.8 to .NET 8, which is a hard runtime break — a single DLL cannot target both, so anything covering Revit 2022–2024 and 2025–2026 needs two compiled builds behind one installer, not a recompile-and-hope. We handle that split for you with shared source and per-version conditional compilation.
There is also a moving target worth planning for: Microsoft ends .NET 8 support on 10 November 2026, and Autodesk has already previewed moving Revit 2025/2026 onto .NET 10, so an add-in written today should be structured so that a future runtime bump is a rebuild, not a rewrite. A second easy-to-miss detail after the .NET 8 move: WinForms MessageBox and Revit’s own TaskDialog can now collide by name, so UI code often has to fully qualify Autodesk.Revit.UI.TaskDialog — small, but it breaks naive ports.
One more thing on scope: heavy work belongs in an external command or external event, not in document modifications fired from idling, or Revit will throw outside a valid transaction. We design around the Revit transaction and threading model from the start, which is the usual reason a “quick Dynamo conversion” turns fragile when it is rushed.
Process
- You describe requirements and goals — free consultation.
- We confirm the scope and send a fixed quote with completion time within 48 hours.
- 50% deposit, development starts.
- You test the build and give feedback (2–3 revision rounds included).
- Delivery, final payment, and after-delivery support.
