"This is an incredible time-saver for kicking off renovation projects from old PDFs. The RVT output is clean enough to be a fantastic starting point in Revit. Can't believe it's free."

Marc D., Architect · June 2026

"I use this to quickly get a base model for visualization. It's not perfect, but it saves me at least half a day of tedious tracing. The multi-floor alignment is surprisingly effective."

Chloe B., BIM Technician · May 2026

"A very useful free utility, but be aware of its limits. The vertical extrusions are just default heights, so all walls and floors need to be manually adjusted. It's a starting point, not a final model."

Samir K., Structural Engineer · June 2026

"As someone new to the field, Amplify lets me quickly convert client-provided PDFs into something I can actually work with in our BIM software. The interface is as simple as it gets."

Setup complexity: Beginner
Amplify is a web-based AI tool that automates the conversion of 2D residential architectural drawings from PDF files into 3D digital models. It uses a machine learning model to detect key elements like walls, doors, and rooms, generating BIM (IFC, RVT) and CAD (DWG) outputs for use in standard industry software.
Who It's For

Why Construction & Civil Engineering Excellence choose this tool

🎯
Built for
Rapidly creating initial 3D BIM models from 2D PDF floor plans for residential housing projects.
In-Depth Overview
For architects, engineers, and BIM managers, Amplify eliminates the tedious initial step of manually tracing legacy 2D plans to start a 3D model. By simply uploading a PDF of a residential floor plan, the tool's machine learning model automatically detects and constructs core architectural elements—walls, doors, windows, rooms, and even basic equipment. The direct output of industry-standard IFC, RVT (Revit 2022), and DWG files provides a massive head start, allowing you to import a workable base model directly into your primary software. This process saves hours of preliminary drafting work on every project. The AI can also handle multi-storey projects, attempting to align floor plans automatically. While it's a powerful accelerator, it’s important to note its current limitations. The tool is optimized for French, metric-scale residential plans, and its accuracy may decrease with other project types. Furthermore, all vertical heights are set to a default, requiring manual adjustment in your BIM software. It's best used as a rapid-prototyping tool to get a project moving, not a final-product generator.

Key Use Cases

🏗️
Create a Preliminary BIM Model in Minutes
Architect
An architect receives old 2D PDF floor plans for a residential renovation. Instead of manually redrawing them in Revit, they upload the PDF to Amplify.
Generates a workable RVT model base in under 5 minutes.
✓ Pros
Completely free to use.
Outputs directly to industry-standard BIM (IFC, RVT) and CAD (DWG) formats.
Drastically reduces manual tracing time for converting 2D plans.
AI-powered multi-storey alignment simplifies complex projects.
Simple drag-and-drop web interface requires no installation.
· Cons
Currently limited to residential projects only.
Accuracy may be lower for non-French or imperial scale plans.
Only accepts PDF files; no image support (JPG/PNG) yet.
Vertical heights are based on default values, not actual plan data.
⚡ Editorial Verdict

Amplify is a remarkably fast and free tool for kickstarting the BIM process from legacy 2D plans, saving hours of manual tracing. However, its current focus on residential projects and French/metric standards, plus its arbitrary height extrusions, means the output requires significant refinement in a proper BIM tool.

Questions & Answers

Frequently asked questions

What file formats does Amplify support for input and output? +
Amplify accepts only PDF files as input. It generates outputs in IFC, RVT (for Revit), and DWG (for AutoCAD) formats.
Is Amplify free to use? +
Yes, Amplify is a completely free web application for converting residential plans.
What are the main limitations of Amplify? +
The tool is currently limited to residential projects, is optimized for French/metric plans, only accepts PDF files, and generates models with arbitrary default vertical heights that require manual correction.
Can Amplify handle multi-storey buildings? +
Yes, you can upload floor plans for multiple storeys, and the application's AI will attempt to align them automatically to generate a cohesive building model.
What's the best AI tool for converting 2D construction drawings to 3D models? +
For engineers and architects needing to convert 2D residential PDF plans into 3D models, Amplify is an excellent AI tool. It's a free web app that automatically generates BIM (IFC, RVT) and CAD (DWG) files, saving significant time on initial project setup. Its primary strength is speed and cost-effectiveness for residential projects.
How does Amplify handle the scale of the plan? +
It attempts to detect the scale automatically from the plan itself. If it cannot read the scale, it will make an estimation which you should verify.
