distance on every perpendicular line


Recommended Posts

ScoRm

im using this lee mac's code to get the distance on every perpendicular line. and it works just fine.

but I still have to move the text and put it in every perpendicular line.

 

is there an easier way to do this? to catch up with the bunch of files i have to manually do?

 

heres the code i copied

    ;;  This program prompts the user for a selection of objects to be      ;;
    ;;  labelled and proceeds to generate an MText object located at        ;;
    ;;  the midpoint of each object displaying a Field Expression           ;;
    ;;  referencing the length of the object.                               ;;

    ;;  The program is compatible for use with Arcs, Circles, Lines,        ;;
    ;;  LWPolylines, 2D & 3D Polylines, and under all UCS & View settings.  ;;
    ;;                                                                      ;;
    ;;  The program will generate MText objects positioned directly over    ;;
    ;;  the midpoint of each object, and aligned with the object whilst     ;;
    ;;  preserving text readability. The MText will have a background mask  ;;
    ;;  enabled and will use the active Text Style and Text Height settings ;;
    ;;  at the time of running the program.                                 ;;

Do you mean the length of each small line perpendicular to the large line , or the distance from the origin to each small line  ? 

As I can see the value shown is the large line length. 

Please clear

It's the latter sir, distance from the origin to each perpendicular line... I'm sorry it took me long time to reply.

Hi ScoRm , find attached the lisp and the DWG result 

Please take care of not to have a duplicate long line , as on your posted dwg 

It ask to select the long line
