How to Fix Revit 8.1 Error When Opening Files in Revit LT
If you are using Revit LT and you encounter an error message that says "(File name).rvt cannot be opened in Revit LT because it was last saved in a version of Revit prior to 8.1", you might be wondering what caused this problem and how to solve it. In this article, we will explain the possible reasons for this error and provide some solutions that might help you open your files in Revit LT.
Revit 8.1
What Causes the Revit 8.1 Error?
The Revit 8.1 error can occur when you try to open a file that was created or modified in a different version of Revit than the one you are using. For example, if you try to open a file that was saved in Revit 2016 in Revit LT 2016, you might get this error message. This is because Revit LT is a simplified version of Revit that does not support some of the features and functions of the full version. Therefore, some files that were created or modified in the full version of Revit might not be compatible with Revit LT.
How to Solve the Revit 8.1 Error?
To resolve this issue, you can try one or more of the following solutions:
BIM 360 Models: If the file was saved from the cloud (BIM 360), it might be a misnamed zip file. Try renaming the file to (file name).zip and then extracting it. You might be able to open the extracted file in Revit LT.
Full Version of Revit: If you have access to the full version of Revit (not LT), you can try to open the file in that version and then save it as a new file with a different name. Then, try to open the new file in Revit LT.
Revit Extensions: If the file was created or modified using some of the Revit extensions, such as ArchiCAD Connection or Sigma Revit Integration, you might need to install those extensions on your computer and then open the file in Revit LT .
Backup File: If none of the above solutions work, you might need to look for a backup file that still works with Revit LT. You can check your local or cloud storage for any previous versions of the file that were saved before it was modified in a different version of Revit.

What are the Benefits of Using Revit LT?
Revit LT is a simplified version of Revit that offers some of the core features and functions of the full version, such as 3D modeling, parametric design, documentation, and collaboration. However, it also has some limitations and differences that you should be aware of before choosing it for your projects. Here are some of the benefits and drawbacks of using Revit LT:
Cost: Revit LT is cheaper than the full version of Revit, which can be a significant factor for small businesses or individual users who have a limited budget. You can also choose to subscribe to Revit LT on a monthly, yearly, or multi-year basis, depending on your needs and preferences.
Performance: Revit LT is faster and more stable than the full version of Revit, especially when working with large and complex models. This is because it does not support some of the advanced features and functions that can slow down or crash the software, such as rendering, analysis, massing, and structural modeling.
Compatibility: Revit LT is compatible with most of the file formats and standards that are used in the architecture, engineering, and construction (AEC) industry, such as DWG, DWF, IFC, PDF, and BIM 360. You can also import and export files from other Autodesk products, such as AutoCAD and SketchUp.
Learning Curve: Revit LT is easier to learn and use than the full version of Revit, especially for beginners or users who are transitioning from 2D to 3D design. It has a simpler and more intuitive user interface that focuses on the essential tools and commands that you need for your projects.
What are the Limitations of Using Revit LT?
Revit LT is not suitable for every project or user, as it has some limitations and differences that can affect your workflow and results. Here are some of the things that you cannot do with Revit LT:
Rendering: Revit LT does not support rendering within the software, which means that you cannot create photorealistic images or animations of your models. You can only use basic shading modes or export your models to other software for rendering.
Analysis: Revit LT does not support analysis within the software, which means that you cannot perform calculations or simulations on your models, such as energy analysis, structural analysis, lighting analysis, or code checking. You can only use external tools or services for analysis.
Massing: Revit LT does not support massing within the software, which means that you cannot create conceptual designs or organic shapes using free-form modeling tools. You can only use predefined forms or import massing models from other software.
Structural Modeling: Revit LT does not support structural modeling within the software, which means that you cannot create or edit structural elements or systems, such as beams, columns, foundations, trusses, or braces. You can only view structural models that were created in the full version of Revit.
Collaboration: Revit LT does not support collaboration within the software, which means that you cannot work on the same model with other users at the same time using worksharing or central files. You can only use BIM 360 to share and sync your models with other users.
