Vintech Duct

Vintech Duct  is a CAD/CAM system for parametric design, pricing and NC programming of orders for unfolds of fittings of HVAC systems,


  • design of unfolds of duct parts using libraries with parametric macros for rectangular, round and conical fittings, taking into account the technology of assembling,
  • automatic and interactive true shape nesting and NC programming,
  • order management and organisation of CNC manufacturing.


The Vintech Duct bundle includes:

  • Vintech Duct – CAD/CAM system for design, true shape nesting, NC programming and pricing of orders for unfolds of fittings of HVAC systems;

  • Library Vintech rDuct – parametric rectangular, round and conical fittings and transitions between them;

  • Functionality based on Vintech RCAM-Pro for true shape nesting and NC programming;

  • Vintech NCV – System for verification of NC programs for thermal cutting, with DNC for program packages on the RS-232 serial interface to CNC controllers as Burny, Linatrol, Mazatrol, Amada.

Vintech Duct

  • Manages data for nesting orders consisted of plate parts.
    The parts are created by inputing parametric dimensions in macros from the libraries with fittings or by importing their CAD geometry from files created with universal CAD system.

  • Creates fittings from parametric macros according to assembly, technological and customer requirements for creating the unfolds of their parts.

  • Controls the sequence of steps for creation of nesting orders, parts, nesting jobs, nesting layouts, NC programs, labels and inquiries.

  • Allows editing of parts from the nesting order using universal CAD system and their replacement in the order.

  • Creates offers for orders and defines prices based on area or weight, perimeter and time.

  • Prepares nesting jobs on orders and visualizes the status of the job.

  • Automates the creation of processing technologies using Datasets database.

  • Monitors the information and status of each part; Provides advanced tools for managing changes in orders,

  • Saves NC program package and submits it to the DNC system in Vintech NCV

  • Saves listings for nesting layouts and marking labels for the parts in the order of their cutting.

Vintech rDuct is a set of parametric libraries for rectangular, round, conical air duct fittings, transitions between them and standard flat parts.

Each fiting from the library is selected visually and the geometrical parameters are entered directly in the dimensions in its draft.

A created fitting can be saved for later use in normal to any type of part. Parts, imported from external CAD files, can be added in the structure of a fitting from the normal.

Working with library Vintech rDuct allows for:

  • adding a fitting in order by setting parameters or by selection from normal, with no need for a CAD system,
  • automatic break down of fitting to unfolded parts,
  • compensation of elongation or contraction of bended parts.
  • Vintech Duct limits to the highest degree the incorrect actions with the system.
  • Works in mm or inch and gauge. Supports weight of materials in kg or lb.
  • Takes into account the requirements of the HVAC ducts production. Allows the user to define:
    • type and size of connections/flanges,
    • type and size of seams and slits,
    • markings - with labels or with ink-jet printer.
  • Supports types and dimensions of seams and flanges in Technological datasets,
  • Opens nesting job from Vintech Duct and creates nesting layouts and NC programs.
    Vintech RCAM-Pro, multi-plate nesting

  • Provides user interface with integrated methods for nesting and management of processing technology. Provides a new standard for usability with Project navigator, libraries 'Layouts', 'Blocks' and 'Parts', interactive nesting with „handles“, paths with „handles“ and „halos“, etc.
  • Imports, checks and converts geometry of parts from DXF, DWG, SVG, DSTV and ESSI files.

  • Nests automatically and interactively with true shape or in a pattern, with on-line control against overlapping.

  • Creates multi-plate nesting on whole plate blanks or usable remnants.

  • Creates paths with optimisation according to the type and length of the contours, with on-line control against overlapping of path elements,

  • Automatically and interactively solves special tasks for true shape nesting, such as common cuts, chain cutting, circumventing parts with cutting paths, cutting with bridges and others.

  • Optimises the sequence for cutting of parts, taking into account the part by part and levels of insertion. Allows interactive creation of the route of rapid moves.

  • Vintech Duct uses a configurable postprocessor for generation of NC programs for CNC machines for thermal cutting, and:

    • generates NC programs in ISO/EIA and ESSI command systems,

    • allows the creation of NC programs for cutting and text marking,

    • allows the creation of NC program packages by order.

  • Generates documents from the current job in HTML, DXF and PDF formats. When needed, the listings follow the sequence of cutting of the parts and layouts in the order.

    Vintech Duct generates:

    • nesting layout listing file,

    • label listing file,

    • technological and organisational documents.

Vintech NCV is designed for verification of NC programs and program packages for thermal and jet cutting.

NC program verification

Vintech NCV creates a graphic simulation of the processing path of ESSI and ISO / EIA NC programs, and:

  • checks for correspondence between the NC commands and the paths of the graphic simulation,

  • verifies NC programs with subprograms in absolute or relative coordinates, with translation and/or rotation of the subprograms,

  • allows direct editing of the NC programs,

  • uses CNC machine profiles to verify programs with different structure and format,

  • monitors program registers and calculates the number of pierce points, the time and distance for rapid and cutting moves,

  • creates a technological sketch of the NC program in PDF format and specification in HTML.

Vintech NCV loads NC programs and NC program packages in the CNC controller via serial DNC interface. Allows management of the DNC interface by the CNC controller (Linatrol, Burny, Mazatrol, Amada, etc.).

  • Loads NC programs in the order of processing, allows selecting and loading a single plate or part from plate.

Vintech NCV converts ISO/ESSI NC programs in AutoCAD DXF file format.

System requirements and localizations


The CAM systems Vintech Duct and Vintech NCV work in the environment of Microsoft Windows 10 / 8.1 / 7

They are localized in English, Bulgarian and Russian. There are no limitations for the localization language in the system.

The licenses are activated by a hardware key WIBUBox/U+. The key is installed in a USB port of a local computer or file server in the factory's network.
The license for Vintech Duct is a local licence and for Vintech NCV it is a network license.
