Key Features

  • Facilitates interoperability between CAD/BIM and structural analysis software.
  • Imports structural geometry and load data efficiently.
  • Maintains a link to original design files for updates.
  • Proprietary binary format optimized for Autodesk Robot Structural Analysis.

Best For

  • Connecting Autodesk Revit or AutoCAD models to Robot Structural Analysis.
  • Performing detailed structural analysis on imported designs.
  • Streamlining the workflow from structural design to engineering analysis.

Less Ideal For

  • General 3D model storage and sharing (use IFC, DWG, RVT instead).
  • Archiving raw design data (use native application formats).
  • Interoperability with non-Autodesk structural analysis software.
  • Publicly sharing or distributing structural analysis models.

Common Use Cases

  • Importing architectural models into structural analysis software.
  • Transferring building information models for structural design verification.
  • Linking 3D structural designs from Revit or AutoCAD to Robot Structural Analysis.
  • Collaborating between architects and structural engineers.

How to Open It

  1. Import the .arl file directly into Autodesk Robot Structural Analysis software.
  2. Ensure Autodesk Robot Structural Analysis is installed on your system.
  3. The file is not intended for direct viewing; it requires the specific software for its intended function.
  4. If you receive an .arl file, ask the sender which version of Robot Structural Analysis they used.

What is a .arl file?

An .arl file is a proprietary format used by Autodesk's Robot Structural Analysis software. It serves as a link file, connecting structural models created in other CAD or BIM applications to Robot Structural Analysis for detailed engineering analysis. This allows engineers to import geometry and loads from design software and perform structural calculations, simulations, and checks without needing to recreate the entire model. The .arl file acts as an intermediary, facilitating data exchange and ensuring consistency between design and analysis workflows. It is crucial for projects that require advanced structural engineering assessments.

Common Problems with .arl Files

⚠️ Cannot open the .arl file.
Ensure you have Autodesk Robot Structural Analysis installed. This file format is not viewable with general-purpose software.
⚠️ File won't import correctly into Robot Structural Analysis.
Check the compatibility of the source CAD/BIM software and its export settings. Ensure you are using a compatible version of Robot Structural Analysis.

Frequently Asked Questions

What is an .arl file used for?

An .arl file is used to link structural models from other design software (like Revit or AutoCAD) into Autodesk Robot Structural Analysis for engineering calculations and simulations.

Can I open an .arl file with a regular text editor?

No, .arl files are proprietary binary files and cannot be read or edited with a text editor.

Is the .arl format open source?

No, the .arl format is proprietary to Autodesk and is not open source.

Technical Details

The .arl format is a binary file structure developed by Autodesk, designed to contain specific data elements relevant to structural engineering analysis. It typically includes geometric information, material properties, load cases, and boundary conditions transferred from source applications. This format is proprietary and primarily intended for use within the Autodesk ecosystem.

Did You Know?

The .arl extension likely stands for 'Autodesk Robot Link'.
This format is specifically designed to streamline the BIM to structural analysis workflow.

Security Information

As a proprietary binary format from a reputable software vendor (Autodesk), .arl files are generally safe. However, like any file downloaded from the internet, exercise caution and ensure the source is trusted to avoid potential malware if the file has been tampered with.
