Mozart Liszt Virtual-Design Support Contacts

Mozart is a CAD realized following the requests and suggestions of leather goods pattern-makers to simplify and expand their work being them free to design according to their ideas.

Mozart requires AutoCAD« or ZWCAD«. The license of Mozart does not include the license of AutoCAD« or ZWCAD«
Mozart 7 is available with the same functions for AutoCAD« from release 2000 up to 2021 (2017 for Mozart 6) and for ZWCAD« 2015+, 2018, 2019,2020 and 2021.

  • Quick learning
    Built on pattern-makers' requirements Mozart shares his working method giving full liberty to design the model. The pattern-maker can concentrate himself on the model to be realized. He does not have to code the materials or pieces before or during the drawing.

  • Freely customizable
    The user can easily change many settings of Mozart: colors, the method of calculating the bill of materials and the bill of working times and many other parameters.
    Mozart can also load and use custom toolbars, scripts and commands written by the user.

  • Flexibility
    The user is free to choose the names of the patterns and their hierarchy. Each pattern is a single file and Brands, Lines, Seasons etc. can be organized by folders.
    Each pattern is independent from the others and can be copied or moved in whole or in part from one folder to another like any other file.
    The bill of materials and the bill of working times can be performed in different ways and the reports are produced as ASCII text or Excel document.
  • Data exchange
    The patterns can be read using many others CAD programs. The cutting can be done using a wide range of machines from vertical or flatbed plotters to knife, laser or water-jet cutting machines.
    The bill of materials, the bill of accessories and the bill of working times can be exported to others data management systems.
  • Development
    The open structure of Mozart means it can be constantly improved according to users suggestions and requests.
    The upgrade of Mozart does not oblige the user to upgrade the other components of the CAD system.
    Plug-ins increase the power and the flexibility of Mozart.

Plug-ins add specific functions to Mozart. The user himself can write his own plug-ins, Mozart will automatically load them.

Plug-ins allow to customize Mozart's installations to the needs of the user and reduce the cost because they avoid the purchase of what is not needed.

Users can request the development of personal plug-ins to create special reports or drawing functions. On request personal plug-ins are not available to other users in order to protect their confidentiality.


  • Calculation of material consumption
    This plug-in provides two methods for processing an estimate of material consumption by creating reports in text or Excel format.
    The automatic method includes three levels of waste and the possibility to set the geometric approximation of pieces giving considerable flexibility of configuration.
    The placement method allows you to extract all the pieces in the required materials and make a manual placement of these pieces to calculate the nested surface.
    Consumption data can be exported to PDM and other data management software via text files.
    This plug-in also generate the Pieces Sheet in text or Excel format and the Piece Sheet with the shape of each piece in Excel format.
  • List of accessories
    This plug-in defines the accessories (zipper, cords, hinges, rivets, etc.) by placing them directly on the pieces or adding them to a list to then make the bill in text or Excel format.
    The list can be exported to PDM and other data management software via text files.
  • Automatic print table creation
    This plug-in automatically arranges the pieces to be printed on the surface corresponding to the cardboard sheet to speed up the printing operation.
    The pieces that are too large in size of the sheet are placed next the printing table for a manual placement.
  • Translator
    This plug-in translates texts from one language to another. The translation is based on a multilingual dictionary consisting of an Excel sheet that is created by the user himself during the translation phase.
  • 3D surfaces unfolding
    This plug-in adds a command to unfold a 3D surface (mesh or Coon's surface) and obtain the equivalent 2D surface.
    The command requests to select the 3D surface to unfold and the optimization level, then creates the 2D surface.

  • Technical data sheets
    This plug-in realizes the technical sheets of the model with the indications of the main phases of cutting, preparation and assembly.
    The sheets in A4 format can be printed and exported to PDF.
    Among the available phases: cutting, splitting, skiving, recutting, gluing, thermo-gluing, dyeing and marking.
  • Creating polyline from spline (NURBS)
    This plug-in creates a polyline having the same shape of the selected spline (NURBS) simply indicating the optimization level.

  • Basic patterns construction
    Some type of patterns are particularly suited to be automated. Using a simple interface this plug-in automatically creates the 3D model and the outlines of main pieces. The user can chose between 9 types of patterns, each pattern subdivided into several types. The 3D pattern can be used to evaluate the proportions and to develop the Virtual photography. The outlines can be used as a starting base to develop the whole pattern.

  • Interface DXF AAMA
    This plug-in helps the dialogue between Mozart and programs or cutting machines that accept DXF AAMA 292.
    Extremely customizable allows the creation of multiple configurations to better interface every other program or cutting machine that supports the AAMA 292 standard.
    This plug-in overcomes the limitations of the standard AAMA 292 as it can define five levels of quality areas, thirteen drilling tools, three types of notches, the pieces to be mirrored or that cut for more than one bag, the objects to be projected on the plane of the cutting machine, the cutting direction and horizontal and grain and stipe lines.
