Summary
Sequenza is an Autodesk Revit add-in designed to automate the extraction of construction sequence information from a Revit model and convert it into structured files for 4D construction simulation. It bridges Revit model data with downstream tools such as Navisworks TimeLiner and 3ds Max by generating the task, component, and animation data needed to build a construction timeline.
Core Purpose
The primary purpose of Sequenza is to eliminate the manual effort required to create construction sequence data for 4D workflows. Instead of building Navisworks TimeLiner task hierarchies and element assignments by hand, users can generate structured CSV outputs directly from the Revit model. This allows project teams to spend more time refining the actual construction logic and less time assembling the underlying data structure.
Model Reading and Grouping Workflow
Sequenza reads the active Revit project and organizes model elements by level and category. This grouping creates a practical construction-oriented structure that reflects how work is commonly planned and sequenced in the field. By grouping elements into level-category packages, the tool can generate a manageable hierarchy for construction simulation while still preserving a clear relationship between model elements and schedule tasks.
As part of the process, Sequenza assigns shared parameters that encode each element’s position in the construction timeline. These parameters help identify sequencing information inside the Revit model and support consistent export into the downstream simulation files.
Export Outputs
Sequenza generates three primary output files for 4D coordination and visualization. The Simulations Identification CSV is used for importing tasks into Navisworks TimeLiner. The Simulations Components CSV links Revit model elements to those construction tasks, creating the relationship between the geometry and the timeline. The MaxScript Animation file supports playback in 3ds Max, allowing the exported sequence to be used for animated construction visualization.
