Export circle as a circle not 4 arcs

[GrayTech CNC]

I need help with this please.
I have circles in V-Carve as holes that will be drilled.
Using Biesse CNC machine with a drill block to import the dxf from V-Carve.
The holes come from V-Carve as 4 arcs.
I need to select a circle in the Biesse software in order to use the Boring operation.
Is there any way V-Carve can export a circle as a circle and not 4 arcs?

You need to know what your software's definition of a circle is. A circle as a circle doesn't explain it. In vector terms it can be 2, 4 or more arcs, a series of bezier curves or a series of very short line segments.

As you're using DXF the bezier option is out so it's some combination of arcs (most likely I would think) or short line segments.

What other file formats does your Biesse software accept? You might be better off using something other than DXF

How about asking Biesse why their software cannot figure out that 4 arcs with the same center point with coincident endpoints form a circle?

Way the heck back in my previous life I did just that for the software I wrote. Not even a big deal.

Give ya a hint here, machine companies usually are more interested in selling iron than getting the software correct. Just my opinion after 40 years in the industry ::::shrug::::::
