Technical Characteristics

Lantek Flex3d Steelwork is a system that includes database technology. This eliminates the need for the user to continuously duplicate the entry of information to create a beam or tube section. The parametric technology of this system allows the user to select a base section and then modify the measurement. The result is complete management of different profile products and remnants that are rapidly available on file.

While Lantek Flex3d Steelwork may be a standalone product, it is maximized when integrated with the Lantek Manager andLantek Integra Management Software Systems (MES/ERP). This integration incorporates features that start at the sales quotation level (jobs or projects) and continues with the launch of orders and production flow including: material needs, reservation management, purchases, and cost controls. It also incorporates workshop data collection, the integral management of warehouses, inventory of beams, sheet metal, tubes, remnants, commercial products, and finished goods. The system has total traceability management.

DSTV, SAT and CAM Importers

Lantek Flex3d Steelwork imports data generated by the leading structural steel CAD systems using DSTV, SAT and CAM files. The system converts the DSTV, SAT and CAM files into the native format for Lantek Flex3d, which easily allows the user to apply modifications. In addition, this module will import various properties of a file, such as the material, quantity and thickness — all of which simplify the process for cutting preparation.

Cutting Profiles Simulation

Lantek Flex3d Steelwork allows the user to simulate each machining operation whether it is drilling, punching, the cutting head, or the work zone. If the resultant simulation is acceptable to the user, Lantek Flex3d Steelwork will automatically generate the NC file for the machine and the user can view this data in the same environment. As seen in the illustrations, the simulation is of all machining operations and the trajectory of the cutting head (plasma or oxy-cut). When collisions are found, the user can repair them by stopping the simulation and correcting the trajectory.

The user can see all of the parameters of cutting during the simulation and, while viewing, make zoom movements, rotations or axis positioning adjustments to the profile. Viewing is totally interactive during simulation with options for viewing step-by-step, forward or rewind.

    Verification status

Automatic fixtures calculation

Lantek Flex3d 5x automatically generates the fixtures necessary for positioning the part correctly on the machine table.

Taking as a base the desired position and height of the part above the cutting table, the system provides a user-modifiable holding grid, where the user can decide how many fixtures will hold the part in place and their locations.

When the appropriate holding grid has been designed, Lantek Flex3d 5x generates the solids necessary for positioning the part on the table. Automatic fixture calculation takes cutting contours into account, so that the calculated fixtures do not interfere with either the cutting head or any of the holes to be cut. This saves valuable machine time, normally associated with program verification in the machine.

These fixtures can be revised in 3D mode. The design or the position of the fixtures can be modified and recalculated at any stage of the process.

When the correct fixtures are in place, the user can automatically transfer the 2D geometry to Lantek Expert Cut or Lantek Expert Punch for the parts to be cut on any available machine.


Lantek Flex3d 5x automatically detects all the part cutting contours, allowing automatic or semi-automatic machining of these contours. The qualities to be applied to each contour can also be selected by user. The automatic machining sequences and model intelligence is generated irrespective of where the 3D CAD design data originated. As a result, Lantek Flex3d 5x enables manufacturing of products directly from design data, eliminating potential errors.

After machining, the system allows entire work environment simulation. The software and post-processors include a three dimensional model of the appropriate machine and cutting head. Lantek Flex3d 5x automatically detects any possible collisions of the head with any other elements involved in the cutting operation, offering multiple possibilities for correcting them. The physical limits of the axis are also considered during the whole process.

Lantek Flex3d 5x permits full cutting direction change. Any cutting vector can be modified, erased or inserted at any point of the contour so it prevents unwanted movements and positions.
