LITIO - 3D Sheet metal unfolder

LITIO - 3D is a sheet metal program that calculates flat (unfolded) sheet development of ducts, rectangle to ound transitions, cylinders, cones, pipe intersections, connections, bifurcations, elbows, etc.
For HVAC, hoppers, cyclones, dust extraction, ducts, conveying systems, silos, piping, etc.
This application helps you to draw your sheet metal developments directly in AutoCAD R2000 and later (no need of DXF conversions).

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 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.System requirementsAutoCAD 2008, 2007, 2006, 2005, 2004, 2002, 2000 (AutoCAD R 200X and/or Mechanical desktop 200X); It does not work in AutoCAD LT
Same hardware requirements as to run AutoCAD (if you can run AutoCAD successfully, you can run the program);

Limitations in the unregistered version60 days trial period
DEMO is limited to OFFSET [dtX or dtY] input = 0.0 . If any of them is different to zero, LITIO 2 will draw virtual objects.
There are also some patterns that are not available in DEMO. LITIO 2 will draw virtual objects [DEMO displays a message in this case].
