LITIO 2.0 sheet metal for AutoCAD and GStarCAD

(For LITIO 1.3 for BricsCAD and ZWCad click here).

Do you need to manufacture sheet metal transitions, cones, pipes, leader & branches, Ys, bends, etc.?



LITIO 2.0 is a sheet metal add-on for AutoCAD and GStarCAD, that calculates and draws the flat sheet development of ducts, rectangle-to-round transitions, cylinders, cones, pipe intersections, connections, Ys, elbows, etc.



It is very easy to use and very versatile. It is ideal for the sheet metal-processing industry: for tanks, vessels, hoppers, cyclones, dust extraction, HVAC, ducts, conveying systems, silos, piping, etc.



I was looking for a program that can layout ductwork pieces quickly and easily and came across LITIO2 program. It is easy to use. Excellent value for what you get. Great program! Don Setzler - Monroe Environmental

Litio 2.0 runs within AutoCAD and GStarCAD as an add-on, pluggin program.


At the moment of the publication of this webpage, it works within:

  • AutoCAD (up to) R2021, starting with R 2000 (and Mechanical Desktop 2000); only Windows versions.
  • GStarCAD 2016 onwards. Only Windows versions. Recommended: 2018, Professional version.

Warning: Litio2.0 DOES NOT run in Academic, Lite, nor LT versions. Litio2.0 was NOT tested with GStarCAD Standard version, and versions prior to 2018. Please check Litio2 compatibility with your CAD system (feel free to run the TRIAL version).



LITIO 2.0 features:

  • Create your own customized transitions with the transitions-generator engine. Just pick two polylines in your drawing's 3D space, which define the two ends of the transition, to get it unfolded.*
  • Create your customized branches. With the new 3D TRIM tool you can trim (intersect) two 3D objects to get, your personalized branches, e.g., a conical branch on an square to round transition (or any other combination).*
  • Create more patterns: we have added more dialogue boxes and new standard patterns - oblique transitions; Ys; triple Ys; helixes; "S" pipes; conical bends; bends [various possible cross sections]; more branch patterns; intersecting patterns*; free transitions*; etc.
  • Thickness: For better 3D object visualization, LITIO 2.0 drawns 3D patterns showing thickness. (for easier weld bevel preparation and overall 3D experience).
  • Cut the 3D objects you create in LITIO2.0, with a plane with the 3D plane TRIM tool. Get the resulting patterns* and the intersection POLYLINE, e.g., to make a cover of a tank.
  • Create 2D profiles: Get the developments of the most common sheet metal profiles [L, U, Z, S, J, Omega], and create your own 2D profiles: just pick a 2D Polyline, that defines a profile.
  • Language capability: Dialogues, and error and dialogue messages in different languages (adding new languages!).
  • You can choose INTERNAL, EXTERNAL or CENTER LINE [IN/MID/OUT] dimensions on both ends of transformations, independently [e.g., IN on side 1; Center line on side 2].
  • You can shoose IN/MID/OUT contact on bends, Ys or Banches.
  • Get the groove allowances for thin metal sheet seems, automatically.
* Some restrictions apply [see user manual].

I use LITIO2 software to draw tapered cones (and other ductwork parts) to a flat pattern. I love the fact that I can control the points that the measurements I input are applied (in mid out). That is huge. (...) Litio2 is an incredible value and a very useful tool. You did a great job developing it! Herman Moats

I think LITIO2 is an outstanding product. It is perfect for the jobs I do. It is well worth the money. I think this is the best buy I have ever made as far as programs go. I would recommend it to everyone. Dean Rodriguez - DKR Construction
