DXFTool For CorelDRAW Professional Edition

http://www.LeonardCNCSoftware.com

The DXFTool Professional Edition is a utility program that provides very high quality DXF files for use in CAD / CAM programs.  They are also very useful for Laser and Vinyl cutting systems that use DXF files since text handling is optimized and you do NOT have to ever convert your drawing to curves.  The advantages of this tool are provided by conversions of the bezier curves in CorelDRAW to LINE and ARC DXF entities only.  What this means is that instead of a large number of very short lines the DXF file has as many smooth curves as can be made from the CorelDRAW shapes in your drawing.  The Professional Edition has three types of exports.  A simple DXF file which has only LINE and ARC entities, a DXF file that has POLYLINES for each shape consisting of small line segments only and a DXF file that has POLYLINES with ARC bulges so that each shape is a fully linked series of LINE and ARC entities.  We call this export type a POLYARC.

A simple circle can be hard to cut when it is many small lines instead of arcs as most CAD programs would make it.  Here is a circle from CorelDRAW.

The CorelDRAW DXF export produces this result.  It is NOT very friendly to most CNC systems.  It is a series of lines as defined by the curve resolution inside CorelDRAW.

The DXFTool Professional Edition export is at MOST 4 arcs.  This is a large reduction in node count and an even larger saving in cutting time if your CNC system stops at every end of line.  You can also have circles that are two arcs, one arc and a DXF CIRCLE entity for the smallest possible DXF files.

Note that the 1 arc circle and the DXF circle entity are essentially identical.  It just depends on what your software needs.  This allows the DXF file to be optimized for applications where the size of the file is very important.

The DXTool Professional Edition is the best solution for using CorelDRAW with CNC.  CorelDRAW is a world class drawing program and now it also does CNC very well!
