dxf import

[TimN]

When I import this dxf to intercon it loses the 8 arcs and only the straight lines appear, even though it was all joined before exporting. What am I missing here?

I don't see anything wrong with the file.

I was able to read it in CNC12 offline/demo v5.00.

What CNC11 or CNC12 software version are you using?

Yes that’s the correct file.
I believe my software is the same, v 5.00 cnc12.
Maybe I should look at my dxf export options.
Do you know a way to select a real point as the zero reference? When you zoom in the reference point changes and I can’t select an exact corner, for example.

By "a real point", I assume you mean known numeric coordinates (presumably in the drawing, relative to the drawing's zero point).

I do not know of any way you can just enter such an offset.

The best approach, if you cannot get the CAD coordinates to be where you need them, is probably to just include a POINT entity in the drawing, at the location where you want your part zero point to be.

Then you can click on that point and press F2 to select it as the part zero, as the first step after loading the DXF file.

What CAD are you using? Some systems allow you to set the origin of the drawing. There are a variety of options for exporting DXF files some work better than others; it will depend on your CAD as to what's available

I'm using Rhino, but not very experienced. I do know that Rhino has an export with origin option. This could be what I need to figure out.

Intercon allows you to use the crosshairs to reference a zero location that is as close to the part as you place the crosshairs, but doesn't seem to select an exact point, end of line/arc for example.

I am not familiar with Rhino but I expect there is a way to show an X-Y and Hopefully Z axis or plane. That is the origin. in Fusion360 and Creo items are often drawn relative to that and optimally drawn on the Z plane referencing X and Y.
In Creo it is possible to create several coordinate systems so I always added one, for a mill, that was in the top left corner of the CAD part; as the part would be put in a vise; where X0 could be touched from the left, Y0 was the back jaw and Z0 was the top of the stock. This made it easy to import into a CAM system. Fusion has the ability to orient the stock for its CAM .
In Creo, when exporting from a 2D drawing, the 0-0 coordinate was at the lower left of the border so I would place the 2D sketch at that point - HTH
