This software for BricsCAD and ZWCAD creates unfolded sheet metal designs for various shapes including transitions, cones, and elbows. It is ideal for designing HVAC systems, hoppers, ducts, silos, and piping.

One of the best things about LITIO 1.3 is that it allows you to draw your sheet metal developments directly in BricsCAD & ZWCAD. The steps of use are quite simple - all you need to do is select the 3D surface that you want to unfold. You can choose to either select the inside, outside, or mid cross-sectional dimensions and/or height specifications. You can also decide whether or not you wish to draw the 3D surface and the unfolded sheet as a mesh (to help you when bending the sheet) or as a 2D contour (to ease cutting). The program also allows you to select the precision of the calculation of the developments.
The program automatically sets the units according to the units used in the current drawing session. Once you have finished inputting the parameters, the program draws the 3D object and the respective development. You can then use the 2D developments for NC CAM cutting (plasma, laser, etc.) or manual cutting by plotting them 1 to 1 (1 d.u. = 1 mm or 1 d.u. = 1 inch) on paper and using these templates to mark the metal sheet and cut it.
LITIO 1.3 is available for various CAD systems including AutoCAD R2000 and later (2019) [no LT; no Academic], GStarCAD, BricsCAD [v.11 and higher (either Classic, Pro and/or Platinum). It does not need BricsCAD's Sheet metal module.], and ZWCAD [ZWCad v.2017 and higher. It does not need ZW3D.]. You can visit the website to check the right download file for your CAD system.
Overall, LITIO 1.3 is an excellent program for anyone looking to create sheet metal developments. It is easy to use and allows you to create accurate and precise developments that are perfectly suited to your needs.
