What is an LFT file?

LFT files mostly belong to Lasercut 5.3. LFT files are not a single, universal file type. They are used in different design and engineering environments.
For example, some LFT files are created by laser cutting systems like Lasercut 5.3. These files contain vector instructions used to guide laser cutting machines. You can find more details on their use at Golden Laser.
Other LFT files are used in the CAD world.
  • AutoCAD Layer Filter Files: These files are used in AutoCAD Civil 3D to manage layer visibility and organization. More info is available at Autodesk Civil 3D.
  • Essae-Teraoka Label Format Files: These hold label design data and are used with the Essae-Teraoka Label Editor.
  • LaserForm Text Files: Associated with the Light Field Tool, they sometimes serve as CAD font files. Visit Light Field Forum for additional context.
  • Jet Database Files: In some cases, LFT files store data in a JetDB format, used by Microsoft Access or for NI LabVIEW test results. More details are at Microsoft Access.
  • FilExt.com note: The exact content of an LFT file depends on the software that created it. To view or edit your file, you will need to use the appropriate application that reads the file’s specific format.

    How can I open an LFT file?

    You need a suitable software like Lasercut 5.3 to open an LFT file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your LFT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a LFT file directly in the browser:. Just drag the file onto this browser window and drop it.

    Programs that open and convert LFT files:

    1. Lasercut 5.3
      See the previous paragraphs to learn more about the main application. LFT files are often referred to as Lasercut 5.3 cads because this type of file is primarily created or used by this software.
    2. 3D Studio (Loft File) by Autodesk, Inc.
    3. ChiWriter
      ChiWriter is a scientific multifont word processor. It was developed and, until 1995, commercially distributed by Horstmann Software Development Corporation, USA. It was designed to work in an MS-DOS environment, though it can also be launched from an icon under Windows 3.xx or Windows 95. It creates its own graphic screen, and some of the resolutions offer mouse support. However, the lack of true Windows support probably led to the downfall of ChiWriter. Since 1995 Horstmann is out of business, and all support for ChiWriter has stopped.
