Here's how to stop em from being placed in a P&ID
1. Open the pid-sup.lsp file using notepad.
2. Search for INSTARW
3. Modify the section to read as follows by adding the NIL value:
(defun initvar (imp)
;; The variable "instarw" controls whether an arrow with symbol
;; name inst-ar will be inserted at the destination end of an instrument
;; line such as pneumatic or electric to indicate source and destination. If
;; you do not want such arrows comment out the appropriate line with a ;
;; The number indicates the scale factor of the symbol.
;;
;; The variable "failsym" controls whether an control valve failure mode
;; symbol is used on the operator stem to indicate failure mode of the valve
(if imp
(progn
(setq instarw nil) ;Instrument arrow size
; (setq failsym T) ;Failure symbol on CV stem
)
(progn
(setq instarw nil) ;Instrument arrow size
(setq failsym T) ;Failure symbol on CV stem
)
)
)
4. Save and Exit
