SPLINES TO ARCS CONVERSION

SPLINES TO ARCS CONVERSION

A feature to convert a spline to arcs with a tolerance value.(And arcs --> spline not just in sketcher...)

Some software do it with just a click.

If possible, a drawing and a part functionality.Thanks

This would be very helpful to have some kind of curve approximation not only the possibility of export as poly line.

This is a big problem in manufacturing as well.  We do a lot of irregular shapes which generate splines for a tool path.  therefore output is very small line segments, which generates a toolpath where tool compensation can not be used.  We need to be able to select a spline and CREO should convert it to a best fit curve of arcs and lines.  This would be a huge help.

So, there is interest in this for sketcher, draft entities, and toolpaths?  I presume the tolerance is linear (do not stray more than X off the source spline).  Is it important, or sometimes important, that the result be C1 (no sharp angles, so no two lines in a row, and arcs end tangent)?

For 2/3-axis tool paths, the software needs to 'project' the spline to a planar surface, then convert it to C1 curvature. This would reduce the number of short line segments being processed. Tool compensation should still be allowed, just enable/disable it on a long enough lead-in/lead-out arc or line.
