If you use CorelDraw for artwork generation and to export to CAM programs, you know the formats you can use are DXF and PLT. Both export in line segments only and do not transfer the smooth arc and curves from the Corel CDR format. Text must be converted to curves and then it's segmented via the export.
All that was before DXFTools.
Crafted as a plug-in for CorelDraw 12 or X3 it gives perfect arcs, circles, text and lines for import into CAM programs like SheetCAM, VCarve, LazyCAM or BobCAD. Your machine can cut nice smooth curves and circles, and your frustration with bad exports will be over.
DXFTool is easy to use and has settings for smoothness VS accuracy. Installs in seconds and is always on the toolbar in CorelDraw for quick use.
