tl xpress – building tool
frequently asked questions (faq)

> What does TL Xpress do?

TL Xpress is a FREE add-in for Autodesk Revit to perform the automatic building of Architecture models by using Rooms delimited by Room Separation Lines and organized as an integrated level (or part of a level) of a conceptual building. By using these Rooms, the user can perform the automatic application of wall finishes and insertion of frames; optional and automatic join of wall, floor and ceiling (post-Revit 2021) elements; optional and automatic creation of wall parts. Basically, it is a way to run a streamlined single execution of several commands of the TL Elements application.

> Which version of Revit should I run to use TL Xpress?

TL Xpress is compatible with versions 2019, 2020, 2021, 2022, 2023, 2024 and 2025 of Autodesk Revit, running on Windows 10 or 11, with .NET Framework 4.8 (Revit 2019-2024) or .NET 8 (Revit 2025) runtime installed.

> What languages is TL Xpress available in?

English and Portuguese-BR. English is the default language for the application. However, if you run Revit in the Portuguese-BR language, TL Xpress will run in Portuguese-BR as well.

> What do I need in order to use TL Xpress?

In order to use TL Xpress, you will need to have an account at the Autodesk App Store, download the installer of the application and run it to install the extensions for the desired Revit versions. Once installed, the add-in can be accessed at the "eTLipse" tab at the Revit ribbon.

> Do I need a paid license to use TL Xpress?

No. TL Xpress can be acquired totally for FREE and no paid subscription is required to use it.

> I already own/use a TL Elements license. Would I get any benefit from installing the free version of TL Xpress?

No. TL Elements contains a fully functional version of TL Xpress as one of its features. You, therefore, already have the same functionalities in the TL Elements application.

> Can I use DWG/AutoCAD lines as reference to create walls?

Using DWG/AutoCAD lines is not directly possible in TL Xpress, but it is possible if the respective feature in TL Elements is executed first. For more information about this solution, click here.

> Can I apply finishes, create floors/ceilings or insert doors/windows to my existing walls in the project? Can I start any of these processes with walls already instantiated in the project?

Yes. Since version 2.1 of TL Xpress it is possible to start the automatic finishing process based on room separators and existing walls as core walls.

> Regarding the insertion of finishes to walls: can TL Xpress insert new walls or just add new layers as new finishes to existing walls?

TL Xpress can create wall finishes in both ways: multiple walls or compound walls. In the Multiple Walls mode, TL Xpress will insert new walls as finishes to the core walls. In the Compound Walls mode, TL Xpress will insert new layers to existing types of compound walls (generating new types). You can learn more about these two construction modes in the TL Xpress guide, available here.

> I do not know how to use the add-in. I am overwhelmed by the amount of features in the User Interface. Where can I understand it and get help?

In the TL Xpress user interface you can hover your mouse cursor over any of the buttons and boxes to open a tooltip that explains the feature they set or execute. Also, you can always refer to the topics of our detailed guides for each main feature of the application. You can find them here.
