Text trim box need help

[germslyde]

I have a lisp that is supposed to create a Polyline box around selected text, trim lines within the box, and then delete the box. I am, however, having some issues getting it to run properly. Everytime I run it, I select the text that I want to use, but I get an error

 

Select Text; error: bad DXF group: (-1 (13.3618 5.59898

0.0))

I am hoping that someone can help me out with this.

 

 
;;; This lisp routine creates a box around selected text, trims all entities within the box, and then deletes the box.

(defun C:TTR (/ TEXTENT TRIMFACT TB GAP FGAP LL UR 
 PTB1 PTB2 PTB3 PTB4 PTF1 PTF2 PTF3 PTF4 BX)
 (setq TEXTENT (entsel "\nSelect Text"))
 (setq TRIMFACT 2.0) ;Set trim gap and text height ratio HERE
 (command "ucs" "Entity" TEXTENT)
 (setq TB (textbox (list (cons -1 TEXTENT)))
   LL (car TB)
   UR (cadr TB)
 )
 (setq GAP (* *TXTH TRIMFACT))     
 (setq FGAP (* GAP 0.5))
 (setq PTB1 (list (- (car LL) GAP) (- (cadr LL) GAP))
   PTB3 (list (+ (car UR) GAP) (+ (cadr UR) GAP))
   PTB2 (list (car PTB3) (cadr PTB1))
   PTB4 (list (car PTB1) (cadr PTB3))
   PTF1 (list (- (car LL) FGAP) (- (cadr LL) FGAP))
   PTF3 (list (+ (car UR) FGAP) (+ (cadr UR) FGAP))
   PTF2 (list (car PTF3) (cadr PTF1))
   PTF4 (list (car PTF1) (cadr PTF3))
 )
 (command "pline" PTB1 PTB2 PTB3 PTB4 "c")
 (setq BX (entlast))
 (command "trim" BX "" "f" PTF1 PTF3 PTF4 PTF1 "" "")
 (entdel BX)
 (redraw TEXTENT)
 (command "ucs" "p")
 (princ)
) ;end trimbox
(princ "\nType TTR to start") 
(princ); end TEXT TRIM.lsp

Thank you in advance for your help

germslyde,

Made a few changes and additions. Seems to work. Could use some error trapping. Enjoy

Here is the TTR program with error trapping and code added to save and restore the system state.
