I have this lips program that will insert a couple of blocks called Chair and Chair2 but it will always insert it in the middle of the support lines, I need it to insert the block at the end of the support lines. what can I do to change this setting? here is a copy of the lisp program I'm using, any help will be greatly appreciated

don't post code in the message like you did then we'll end up seeing happy face symbols instead of the complete code.
use </> Insert/Edit code sample
Just doing a quick glance, the chair insert part of the code happens in 2 locations.
The first is here:
(if
(command "insert" "C:/apps/PT_CAD/pt_supt/chair2" ip (getvar "dimscale") "" bad (strcat (spins ch) " SB"))
(command "insert" "C:/apps/PT_CAD/pt_supt/chair" ip (getvar "dimscale") "" bad ncl (spins ch))
)
The second is here:
(if (< nnc 3)
(command "insert" "C:/apps/PT_CAD/pt_supt/chair2" ip (getvar "dimscale") "" bad (spins ch))
(command "insert" "C:/apps/PT_CAD/pt_supt/chair" ip (getvar "dimscale") "" bad nc (spins ch))
)
They both use ip as the variable for the insertion point of the chair symbols.
Looking further up in the code ip is defined here:
(setq ip (list (+ (car barep1) (* d (cos a)) (* (/ (getvar "dimscale") 32)(cos baroff)))
(+ (cadr barep1) (* d (sin a))(* (/ (getvar "dimscale") 32)(sin baroff)))))
But since you want to place the chairs at the end of the bar line, this time doing a search for the start and end points of the drawn bar line shows here:
(if (not fh) ;COMPUTE SUPPORT HEIGHT AT INTERMEDIATE SUPPORTS
(progn
(setq barep1 (intpt pl1 f n))
(setq barep2 (intpt pl2 f n))
(setq xd (* n s))
and again here:
(progn ;SUPPORT HEIGHT IS AT HIGH OR LOW POINT
(setq barep1 pt1)
(setq barep2 pt2)
(setq h fh)
)
Then the code draws the line here:
(command "line" barep1 barep2 "") ;DRAW UNIFORM SUPPORTS
My best guess is that the end of the support line should be at barep2.
So I would change the setq ip variable from this:
(setq ip (list (+ (car barep1) (* d (cos a)) (* (/ (getvar "dimscale") 32)(cos baroff)))
(+ (cadr barep1) (* d (sin a))(* (/ (getvar "dimscale") 32)(sin baroff)))))
to this:
(setq ip barep2) ; end of support line
Pardon my ignorance, I'm not too familiar with coding but if Im not mistaken, I should erase and replace these lines
(setq ip (list (+ (car barep1) (* d (cos a)) (* (/ (getvar "dimscale") 32)(cos baroff))) (+ (cadr barep1) (* d (sin a))(* (/ (getvar "dimscale") 32)(sin baroff)))))
with this instead? correct?
(setq ip barep2) ; end of support line
Yep give it try
I was barely able to try this but it didnt' work, I will post some screen shots to communicate my intends better. Thanks
Hi Pedean
Support Bars are the magenta lines on the attached image, The chair heights is the block I want to modify to get inserted at the end of the support lines. I'd been trying for a while but no luck. any help will be greatly appreciated
