Changing the width of a specific polyline

[aliasnasrat]

To change the width of a specific polyline without affecting the width of other polyline in a drawing, what command I should use?

Select the polyline you want to modify, open the PROPETIES palette, make the change there.

PLINEWID is the variable you can set to affect the width of polylines drawn from that point forward.

Hi,

after you select that polyline press Ctrl+1 to open properties palette then modify Global width value .

Here's a trick, if you're talking about a "lightweight" Polyline:

(entmod (append (entget (car (entsel))) '((43 . 1.0))))

Put your desired constant width in decimal drawing units in place of the 1.0.  Paste into the command line, and when prompted, select a Polyline.

You could put that into a macro in a Tool Palette button, or a define it into a command name, which could be made to prompt you for the desired width instead of having it built in, etc.

Every thing the others have said, plus you can use the pedit command to edit polyline widths and in a number of other ways not easily available through other methods.
