LITIO is a sheet metal design program, that calculates the flat (unfolded) sheet metal [e.g.: metals like iron, stainless steel, brass, copper, aluminum, etc.] development of ducts, rectangle to round transitions, cylinders, cones, pipe intersections, connections, bifurcations, elbows, fittings, etc.

For HVAC, hoppers, cyclones, dust extraction, conveying systems, silos, piping, tubing, ducting, etc. To draw your sheet metal developments directly in AutoCAD R2000 and later (no need of DXF convertions). This program is shareware.

Steps of use:

Selecting a development...

First select the 3D surface you want to unfold. For example, you would like to make the development of a silo, a hopper, a pipe transition, a tube bend or fitting, a cylindrical duct, a square-to-round, a rectangle-to-round, etc.

Setting preferences...

You can select: either inside, outside, or mid cross sectional dimensions and/or height specifications for the input parameters; to draw or not the 3D surface; to draw the unfolded sheet as a mesh [to help you when bending the sheet] or as 2D contour [to ease cutting], or both; and the precision of the parametric calculation of the developments.

Metric Units/Imperial units: the program automatically sets the units according to the units used in the current drawing session.

Input of parameters...

3D Object, Development, and 2D Contour...

After finishing the input of parameters, the program draws the 3D object and the respective development.

Afterwards, you can use the 2D developments for 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), and using them to mark sheet and cut.

The program runs within AutoCAD (AutoCAD R2000 or later: 2008, 2007, 2006, 2005, 2004, 2002, 2000). It has the same hardware requirements as to run AutoCAD (if you can run AutoCAD successfully, you can run the program). See user manual or click here for more details about installation and use.

The single user license is 48 USD, much less than other similar programs.
