Ellipses in VCarve Pro

Be careful when creating ellipses in VCarve Pro and then exporting as dxf, ai or eps. VCarve Pro will make two identically sized ellipses superimposed exactly on top of each other. This creates havoc when you import into RDWorks and run a simulation, as the apparent priority layer order set by you may not be respected because of the double ellipses. Black is set as the default priority 1st color for layers, and the hidden layers will be colored black. Since you could not see them to color them anything else, the simulation will then do all the visually hidden ellipses as priority 1 ... and then go to your priority 2.

I even tried exporting out of VCarve Pro as a PDF which Inkscape can read, then exporting as dxf out of Inkscape. The problem of double ellipses still holds, but now the redundant ellipse has jagged edges and is merged with the true intended ellipse.

The work around without going back to VCarve Pro is to set the layer property for the ellipse to "hide yes" by double clicking on it in the Work Tabsheet. This will reveal the hidden ellipse as colored black; delete it. Then unhide (set "Hide = no") on the actual ellipse that is colored and you want to keep. Remember to File -> Save the changes before running a simulation.

You can see the issues with the images below. If the outlines in the image are dim on your view screen, just click on it to enlargen and darken.

There is an ellipse underneath the red inner ellipse.

The hidden ellipse is revealed.

See the hidden ellipse now has jagged edges after using Inkscape as an intermediate DXF creator.
