AutoCAD 2018 DXF file curves are faceted in Mach3 and Easel
« on: March 23, 2021, 07:51:08 AM »
In AutoCAD 2018, I  made a simple drawing , a U shaped 3 sided drawing, with the 4th side a curve of radius 150mm. Save as a dxf file and a pdf file showing the dimensions ( see attached).
In AutoCAD, in DWG TrueView and in DWG FastView, and in  DWGSee Pro, the curve is very smooth, no sign of any faceting.

When this DXF file is imported into Mach3, the end result is a faceted curve, and the CNC router cuts it like that.
When the DXF file is imported into Easel (see Inventables.com), the faceted curve appears again , as per the attachment CNC Image.pdf

Can anybody please advise what might be happening to make these faceted curves appear, and the best way to prevent it and get a smooth curve on the CNC router?

kind regards to all,
Joe
