Hi,
There seems an issue with the curve as when you sweep the circle it produces 2 objects not 1.
This corresponds to a end point on the curve.
Removing this point allows the sweep to generate a single object as it should.
Cheers

Hi Barry.
The problem is that there is no tangent between them.
This can be fixed roughly by running the "union" command or by deleting one of the segments, then use the "sweep" command to connect the ends, after applying the "separate" command to the curve. Or make the arcs tangent.
You cannot delete a point, because you will get a nurbs curve, and here you need lines and arcs. Everything else, that is, all kinds of splines, nurbs curves, and so on, are not suitable for this. Most CNC machine control racks allow you to import DXF files, but they should contain only lines and arcs, since initially the structure of the control program is the movement of machine organs along straight lines, which are G1 X...Y...Z... and arcs G2 X...Y...Z... i...j...k... and G3 are the same but in a different direction.

HI Barry, I have broken the curve down to smaller arc segments to try to identify the problem area do you mind taking a screen shot of the problem end point.
Many thanks Alex.

Hi Alex,
attached drawing shows the point.
However taking WN post into consideration this converts that section into a nurbs curve not a arc.
Cheers

Many thanks for the highlight will go over the construction of this curve set another time and see if I get a clean build.
Much appreciated.
regards
Alex.
