Convert Polylines into lines??

hello evreybody, i have a question... and i hope that you have an answer!!!
i've got a polyline... i've exploded it and now i've got both polylines and arcs... with the pedit command, i've converted my arcs into polylines... but is it possible to convert the polylines into lines? because i have to use my drawing file in an other software and it's working better with lines... when i put polylines in it, i take the beginning and the end of my polylines and join them with a line... that's why i need only lines in my drawing... i know that with autocad you can convert lines into polylines but is it the opposite possible?

thanks for your help...

As has been stated, the options to convert a polyline with curves to purely lines is limited. There is a "Decurve" sub option with the PEDIT command, but that will only convert a polylines cuve to a staight line from one vertex to the next.

In lieu of a Lisp or VBA routine, the DXB printer method (with insertion and scaling) is also an option. There is a loss of accuracy, but there will be some loss of accuracy in any arc to line conversion.

If you use WMFOUT , the exporting process can't handle curves and changes them all into segmented lines.

Then you can WMFIN the image, and after a couple of explodes, you have all lines.

You have to include a witness line in the image that is exported, because the scaling is not good and you have to scale the image when importing it.
