Q - question

Total length of lines in a drawing (by layer) - AddLen

A - answer With the free LISP utility CADstudio AddLen you can summarize the total length of all selected lines, arcs, polylines, circles, splines and other curves in your current drawing.

The lengths are also grouped by layers. You can optionally export the results to a SDF text file or to the Clipboard. Since version 1.2 you can also list individual values. Decimal places depend on the UNITS command.

Sample output:

Layer-Length:
0 118.1143
POWER 438.91
PHONE 311.08
LAN 3010.72

You can download the AddLen utility from Download. Run it with the AddLen command.

You can use LISP variables to control the format of text output:
(setq AddLenNoSub T) ; suppress subtotals
(setq AddLen3rows T) ; layer in 3 rows
(setq AddLenNoFile T) ; no export to SDF file
(setq AddLenDecimals 4) ; preset number of dec.places, default = by LUPREC
(setq AddLenSortSub T) ; sort detailed lengths, longest first
(setq AddLenClipMode 1) ; copy to Clipboard (T/1=incl.layer name, 2=just lengths)

Spaces in layer names are replaced by "_".

The AddLen2 command lists also arc lengths (lengths by given radius).
