NX3 CAM issues. Planar Milling. (G02/G03 dropping IJK)

[TACKS652]

I have to Mill a shape similar to an ellipse on a vertical machining center. I have a program that completes the desired task but with one problem. The profile is not being cut properly. The surface is not curved instead the profile has been broken up into line segments. This yields a faceted part.

I have changed the output option from linear to circular and this does not help any. The reason is the Post is dropping some "Not all" of the I,J,K coordinates from the posted file in regards to G02/G03 command lines. I do not understand why the program would post all the I,J,K locations for a file and leave out a select few. I.E, a program consists of a total of 3500 lines. I,J,K will be listed thru to line 3300, and in line 3305 the coordinates will be missing the J component. This cause the machining center I have to flash an error code and will not run the progam.

The kicker is that the next line will have a G02/G03 and list I,J,K coordinates.

Thanks in advance...
