Sequenza

Automated 4D Construction Simulation for Revit

Intelligent level resolution handles every element type, and configuration persists per project. Supports Revit 2019–2026.

Sequenza extracts building information from Revit and exports it as industry-standard CSV files compatible with Navisworks TimeLiner and 3ds Max — automating the entire 4D simulation setup process.

Key Capabilities

📤

Three CSV Exports

Automatically generates Simulation Identification (task-level), Simulation Components (element-level), and MaxScript Animation (frame-by-frame) CSVs.

🏗️

Intelligent Level Resolution

Three-tier strategy assigns every element to a level — direct level parameter (confidence 1.0), host element inheritance for doors and windows (0.9), or bounding box spatial analysis (0.7).

📅

Configuration-Driven

Configurable project start date, working days, hours per day, and export mode — settings persist across sessions using Revit Extensible Storage.

⚙️

26 Element Categories

Processes structural, architectural, and MEP elements including foundations, columns, framing, walls, floors, pipes, ducts, conduits, mechanical and electrical equipment.

📈

Advanced Validation

Pre-flight model validation with statistical analysis, resolution success tracking, and category-wise element distribution — warns before committing to generation.

⚡

Revit 2019–2026

Multi-version support from a single shared codebase — .NET Framework 4.8 for Revit 2019–2024 and .NET 8.0 for Revit 2025–2026.

Export Files

Simulation Identification.csv

Task-level construction sequence for Navisworks TimeLiner — one row per level/category combination with planned start and end dates.

Simulation Components.csv

Element-level assignments linking individual Revit elements to TimeLiner tasks — one row per element.

MaxScript Animation.csv

Frame-by-frame animation timeline for 3ds Max — drives visibility keyframes for construction sequence animation.

Frequently Asked Questions

Sequenza exports three CSV files: Simulation Identification (task-level data for Navisworks TimeLiner), Simulation Components (element-level assignments), and MaxScript Animation (frame data for 3ds Max animations).
Sequenza uses a three-tier strategy: first it reads the element's level parameter directly; if unavailable, it inherits the level from the host element; as a last resort, it analyzes the element's bounding box elevation to find the closest level.
Sequenza supports Revit 2019 through 2026 — using .NET Framework 4.8 for versions 2019–2024 and .NET 8.0 for versions 2025–2026.
Yes. Sequenza stores configuration in Revit Extensible Storage so settings persist per project. You can configure project start date, working days, working hours per day, and export mode.
