Introduction

Negar is an image manupulating software for vector-based drawings to be used in NC milling machines. It lets vector drawing in 2D space using accurate coordinates and editing options to produce required files for a special Numerical Control (NC) machine for cutting cylindrical objects like bracelets. Programming Language: ISO/IEC 14882 C++ Compiled using: GNU C++ and GNU Make Library: Nokia's Qt IDE: Eclipse C/C++ Development Toolkit (CDT) + Qt Integration Platform: Cross-Platform, e.g. Windows and Linux License: Proprietary Development Time: Oct. 2008 ~ Feb. 2009

• Executable Files: Latest stable version ported to Win32.
  [negar-1.1.win32-release.zip]
• Also Required: Qt library is needed. If it is not installed, download its minimum Win32 DLLs from here and extract in the same folder.
  [qt-4.4.3.win32-release.zip]
• Source Files: Can not be made public because it is proprietary. Contact me if you are interested.

The main window is the current workspace containing a number of designs. For opening a previous workspace use File -> Open... or File -> New for a new workspace.

Negar Workspace

To add a new design in the workspace, use Design -> New Design. Other menu items let operations on a existing design like remove, duplicate, change order, and ... A detachable window on the right side shows the current designs in the workspace. When Design -> New Design is selected, a dialog appears which needs a mandatory name in addition to dimension of the design. The brushing PLC is used for cylindrical objects. Thus the x coordinate is in degrees while the y coordinate is in millimeters.

Design Menu

New Design Dialog

When an empty design is created, the desired shape can be drawn using the shape tools in Design menu. The exact coordinates of the position of the mouse is given in the status bar. Edit operations can be performed using Edit menu. Each design has its undo/redo queue and a cut or copied portion can be pasted into another design even in another workspace.

A Design

Edit Menu

The properties of points of the design can be modified in the Design -> Change Points Properties. For example the exact position of each point can be set manually. A parameter number can be assigned to a group of points (used for scaling in the brushing machine). In that dialog, group membership of each point can be reviewed or changed.

Point Properties Dialog

Finally, the workspace can be exported (File -> Export...) to a number of thumbnails and custom macros to be used in brushing PLC and its software. All of the designs will be exported. For each design, two thumbnails (snapshot) can be produced with two different dimensions and file formats. All of the files will be written into one folder.
