Litio 2.0 sheet metal - quick start guide

Litio 2.0 works within AutoCAD, GStarCAD, ZwCAD, and BricsCAD [and cadmate] as an add-on/pluggin program.

At the moment of the creation of this page, Litio 2.0 works within:

  • AutoCAD (up to) R2023; ALL R 20XX (and Mechanical Desktop 20XX) versions; only with Windows.
  • GStarCAD 2016 onwards. Only Windows versions. Recommended: Professional version.
  • ZwCAD 2018 onwards. Only Windows versions.
  • BricsCAD 2018 onwards (BricsCAD 2018 and newer). EVEN in BricsCAD Lite (BricsCAD’s 2D Drafting mode; Litio2 will also draw the 3D folded patterns). Only Windows versions.


  • Litio 2.0 DOES NOT run in AutoCAD Academic, Lite, nor LT versions.
  • Litio 2.0 was not tested with GStarCAD Standard.
  • Litio 2.0 was not tested with earlier ZwCAD, and BricsCAD versions.

Please check Litio 2.0 compatibility with your CAD system (feel free to Download the FREE Trial version).

CADMATE USERS: Preliminary tests of LITIO2 for GStarCAD within CADMATE are promising and indicate that LITIO2 [GstarCAD version] could work in CADMATE environment.

Although we have not yet conducted extensive research, we encourage CADMATE users to download the trial version of LITIO2 [GstarCAD version] and do your own tests.

We look forward to your feedback!

Loading and running Litio 2.0 sheet metal

The program can be manually installed by placing ALL of the Litio 2.0 files in the SUPPORT directory of your CAD program.

    The following are typical SUPPORT folder locations (they may vary according to your operative System [windows] version and your CAD platform):

      C:\Program Files\Autodesk\AutoCAD 2021\Support\
      C:\Program Files\ZWSOFT\ZWCAD 2019\Support\
      C:\Program Files\Gstarsoft\GstarCAD2018\Support\
      C:\Program Files\Bricsys\BricsCAD V21 en_US\Support\

To run Litio 2.0, you first need to load it into your current drawing session. For this type the following in your CAD's command prompt:

    (load "LITIO2")

Load Litio 2.0 sheet metal
in the current drawing session of your CAD

Then, to run the program just type:


Run Litio 2.0 sheet metal
in AutoCAD/GStarCAD

Note: The program needs to be loaded at every drawing session, in which you will use it. If you exit CAD program and enter again, or if you open an existing drawing or you start a new drawing, and you want to use the program, then you need to load it to the current drawing session.

Great program. (It has) lots of patterns available. We reduced workshop time due to the precision and accuracy of LITIO software. We often have non-standard patterns and with LITIO2 we are always able to solve them. Steve Owen

Short introductory and tutorial video

The following is a short introductory and basic tutorial video . It explains how to install LITIO 2.0 in your computer and how to load and run the program in your current AutoCAD/GStarCAD drawing session.

It provides an overview of the settings and configurations. And it concludes with an example development: the parameters and entered and results are got: 3D representation, 2D development and its cutting contour.

Warning: In some operating systems, to run Litio2 your user needs to have the permissions or privileges, to access, write or modify files in the folder where Litio2 files are located (e.g., the SUPPORT folder).
Litio2 modifies the Litio2.cfg file when you make Litio2 configuration [settings] changes. (Litio2 may need to create/modify other files in normal operation.)

To solve this problem, you need to be logged-in as an administrator, and/or, you need to get the necessary permissions or privileges: right click the folder, properties, security tab, give permissions. (If not, when making configuration [settings] changes, they will not have any effect, and LitioLAB 1.0 might crash).

You can also watch the following explanatory video.

Warning: AutoDESK app store users:
If you used the installer downloaded from the AutoDESK app store, the location of your LITIO2 files would be similar to the following one:

    C:\ProgramData\Autodesk\ApplicationPlugins\LITIOsi LITIO2 - 3D Sheet metal unfolding soft.bundle\Contents\
(Please, note that this location could be slightly different, depending on your operating system and language settings;
this location may be hidden;
I recommend you perform a search for the litio2.* files in your hard drive).
