Step import to ACIS solids (AutoCAD) from Parasolid yields a solid model that will have a 2D representation of holes as two arcs in order to show a circle.

This AutoLISP routine will remove the selected arcs and replace them with circles. I used to use this in conjunction with TahlCAM's getface routine. TahlCAM'S drill path routine needed circles to represent drilled holes.

I pulled this routine out of TahlCAM and created a stand alone TahlArcToCirc.fas
that will work in AutoCAD versions through 2009.

I hope someone will find it usefull.

Cheers,
Jim Short
