Way to change all Splines to Polylines automatically?

[Precision]

Hi all, I'm familiar with the pedit command to turn a spline into a polyline, but I'm wondering if there's a way to change all Splines to Polylines automatically to save a hell of a lot of time.

 

 

I've tried loading "Spline-to-Pline" LISP file, It's pretty shocking for keeping a reasonable tolerance and resolution at the same time as I need a line/arc length of at least .3mm for our CNC laser cutter..

 

 

Any thoughts?

In ACAD 2014 there is a multiple option in the pedit command. If you have that option, it should be easy enough to select all the splines and apply the conversion. I did a quick test and it works as expected.
