POLYLINE WITH A SPECIFIC DIMENSION

[Efeezy]

Good Morning:

 

Does anyone have a polyline lisp with a specific dimension? I am placing electrical receptacles in an apartment complex. The polyline needs to be a total of 6'-0" or 12'-0". The polyline will bend around: corners cabinets and pillars. The poly line will not be longer that the predetermined length. 

 

Thank you for your time,

use the LENGTHEN command with TOTAL option? I use a shortcut

(defun c:LT  () (command "LENGTHEN" "TOTAL") (princ))

Ok, I see where you are going with this. I want to draw a poly line and have the length at 6' or 12'. The way the LT lisp is set up it takes an existing pline and makes it a specific length.

Set a perimeter of the room with a poly and use break command?

that's right, and you could create a command that draws a pline first, and then runs the lengthen command. Then provide (getvar "lastpoint") as a response to selecting an object.

This has been answered before, if you draw a pline can get overall length and then reset last point, this though requires that the last segment is a straight and making to 12 would not go shorter than 2nd last point.

 

I think it was Lee-mac that may have responded to prior request I am sure if so he will post.

at least in Bricscad v15, the LENGTHEN command will shorten past 2nd to last point
