Hello Every one,I have Mechanical Shop Drawings Project  Which Draw all Pipes as a Double Line With Offset Equal to the Pipe Diameter, I am Looking To Lisp File convert the Double line to multiline with Mline Scale Equal to the offset, So I Could Filter the Pipes By QSelect  As Per Milne Scale and Count the Quantities For Each Pipe Size. 

You might try our PL2ML utility - see https://www.cadforum.cz/en/qaID.asp?tip=5560But it depends on how the double lines are drawn (AuoCAD LT DLINE?).
