LITIO is a sheet metal fabrication program that
calculates flat (unfolded) sheet development of ducts,
rectangle to round transitions, cylinders, cones, pipe
intersections, connections, bifurcations, elbows, etc.
For HVAC, hoppers, cyclones, dust extraction, ducts,
conveying systems, silos, piping, etc. To draw your
sheet metal developments directly in AutoCAD R2000 and
later (2019), GStarCAD, BricsCAD & ZWCAD (no need to
DXF import/export).
For sheet metal fabrication: roll, bend, and fold your
patterns.
Steps of use: First select the 3D surface you want to
unfold. (You can select: either inside, outside, or
mid cross sectional dimensions and/or height
specifications; to draw or not the 3D surface, and the
unfolded sheet as a mesh [to help you when bending the
sheet] or as 2D contour [to ease cutting]; the
precision of the calculation of the developments).
Metric Units/Imperial units: the program automatically
sets the units according to the units used in the
current drawing session.
After finishing the input of parameters, the program
draws the 3D object and the respective development.
Afterwards, you can 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.

There are LITIO software versions available for:
* 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.], &
* ZWCAD [ ZWCad v.2017 and higher. It does not need
ZW3D.].
