Up to 80%


Reduction in development time for sheet metal parts.

+190 shapes


Extensive library of predefined parametric geometries based on international standards.

Speed


Automatic generation of manufacturing reports, labels, and production documentation.

More than 190 ready-to-use parametric shapes


Access a wide library of models based on DIN and SMACNA standards, including cones, cylinders, elbows, branches, intersections, and hoppers. Select the geometry, enter dimensions, and the system generates the flat pattern ready for cutting, nesting, and fabrication.

Specific configurations for sheet metal


Define key manufacturing parameters such as neutral, inner, or outer fiber, seams, joint types, number of segments, flanges, deflectors, insulation layers, and applicable standards. These settings ensure that each development matches production requirements and workshop conditions.

Production lists and labels


Generate complete documentation for manufacturing, including geometric development lists, part labels, 1:1 scale drawings, frame reports, and insulation details. All outputs can be printed or exported to CAD formats such as DXF for integration with cutting machines and nesting software.

Key Features​

Guided automatic development


The software guides the user through each step. From shape selection and dimension input to flat pattern generation and export for cutting. This reduces manual work and minimizes design errors in sheet metal manufacturing.

2D editor with technical marking


Add folding lines, notches, perforations, and markings directly to the geometry. These elements can be defined based on cutting technology, marking tools, and joint types, ensuring compatibility with CNC cutting processes.

Advanced management of materials and thicknesses


Assign materials, thicknesses, insulation types, and cutting machines to each part. These parameters are applied automatically during development to generate accurate geometries for production.

Configuration of seams, flanges, and joints


Create and manage custom seam libraries and define assembly methods based on material thickness and manufacturing requirements. This ensures consistent results across projects.

3D simulation and development validation


Visualize parts in 3D and validate the flat pattern before manufacturing. The 3D view confirms dimensional accuracy, while the 2D development ensures feasibility for cutting and forming.

Definition of insulators and deflectors


Configure internal and external insulation layers and generate components such as deflectors with precise parameters, including marking, perforation, and dimensions.

Organized and traceable database


Store and manage all geometries and parameters with filters by project, customer, material, thickness, or date. This supports reuse of designs and improves production planning and order management.

Frequently asked questions

In this section, you can find answers to common questions about sheet metal software and duct manufacturing.

Specialized CAD/CAM software solutions automate calculations and standard geometries. They allow the design of elbows, transitions, and joints in seconds.

Lantek Expert Duct supports precise HVAC duct manufacturing while reducing production time.


Sheet metal software includes libraries of predefined geometries and parameters. By entering dimensions and joint types, the system generates the flat pattern automatically.

Lantek Expert Duct produces developments ready for cutting, bending, or forming.

Development in sheet metal is the process of converting a 3D shape, such as a duct or fitting, into a flat pattern for cutting. It is widely used in HVAC systems, industrial fabrication, and metal structures.

This process can be done manually or using specialized CAD/CAM software such as Lantek Expert Duct.

DIN and SMACNA standards are commonly used. They define geometries, joints, and technical specifications for duct components such as elbows, fittings, and transitions.

Sheet metal software applies these standards to ensure consistency and compatibility in manufacturing.

CAD/CAM software for sheet metal supports development, nesting, and cutting processes. These systems generate flat patterns, manage material usage, and produce production documentation.

Lantek Expert Duct is designed for this type of manufacturing environment.

Not necessarily. Many solutions provide guided workflows and simplified interfaces where users enter dimensions and parameters.

This allows workshop operators and technicians to generate accurate developments without advanced CAD knowledge.

Automatic nesting distributes parts efficiently across the sheet, reducing scrap. Material tracking and reuse strategies help control consumption and costs.

These capabilities are typically included in sheet metal CAD/CAM software.

The system produces 1:1 drawings, part labels, frame reports, insulation reports, and geometric lists. These documents support both CNC cutting and manual fabrication processes.

They provide full visibility from the engineering office to the workshop.

In environments without CNC machines, software generates printed layouts used as guides for manual cutting or pantograph systems.

Operators work directly from the generated flat patterns, a common workflow in duct manufacturing.
