Ellipse problem

77ericmorell — Wed, 30 Aug 2023 16:19:53 GMT

I make sketches in Fusion and export them as Dxf's to be used on a plasma table. Recently I needed to use an ellipse in one of my sketches. I intersected 2 ellipses to make the shape I needed, then trimmed the lines so that only the outline was left. All appears fine until I export it. The lines that I trimmed magically reappeared when I open the file on my plasma software. This problem only occurs when using ellipses (I tested multiple other shapes and line types)

Any help would be greatly appreciated

Have you tried reimporting the sketch into Fusion? Can you share the f3d file here?

Thanks Mark

Maybe try and create a new sketch from the original sketch to remove the ellipse sketch effects. In the attached file I Extruded the sketch using the Surface Extrude, then created a new sketch and using Project BODY created a new sketch. I then created a new DXF from it. I attached the DXF and the model I created it from for you to test and look at.

The DXF from Fusion (Created using Save As DXF) opens fine in Rhino3d.

Okay this worked for me, will there be a fix for this in the future? More steps for what should be a simple task can be frustrating.

Thank you for the help

What worked, @jhackney1972 idea? When I open the sketch from Fusion in Rhino with no workaround it opens perfectly, also reimports into Fusion so there's no bug in Fusion. You need to report the problem to your plasma software people.

Just for another test I tried opening the DXF in QCad and no problem there either.
