Ductwork & Nesting

 

“Duct Guardian” is a sheet metal 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.

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.

Fitting storage – powerful database contains locations, zone, positions and date-time of fitting creation.

Some common fittings:  Square to round, Radius branch, Radius offset, Cylinder, Cone:

 

 

 

 

 

 

Duct Guardian in collaboration with DG Nest Pro:

 

 

“DG Nest Pro”, without any exaggeration is the best true shape Automatic Nesting solution currently on the market. Software is designed to support any form (symmetric or asymmetric) in .dxf file and prepare it for machine cutting process: oxy-fuel, plasma, laser, water jet. By it’s universal orientation, Software is applicable and highly usable in textile, metal, wood, ship-building industry or any industry that is related with sheet cutting and production over CNC machines.
The speed of loading dxf and nesting session can depend on complexity of your CAD export drawing outputs (points density in circles, arcs).
