hehe, maths? I had to take my GCSE twice - grade E 1st time, grade D second time.
Was always better at languages.

Now I have an impressive CAD program to work out all of my sums etc for drawing work. Who needs a pen and paper anymore?

Now I do something a little in line with algebra (in as much as it has alkward syntax and rules etc) but completely different:

;;; DRAWING / PLOT SETUP ROUTINE FOR ******** DRAWINGS 1:100 @A0
;;; SETS LIMITS AND LOCKED VPORT IN PSPACE WITH CORRECT PLOTTING
;;; SETTINGS BEFORE PROMPTING USER TO SAVEAS.
;;; CREATED BY **** **** : 10/10/06.


(DEFUN C:A0-100    ()
  ;; SWITCH TO M/SPACE
  (COMMAND "TILEMODE" "1")
  (COMMAND "ZOOM" "E")

  ;; SWITCH TO P/SPACE
  (COMMAND "TILEMODE" "0")

  ;; P/SPACE SETTINGS
  (COMMAND "LIMITS" "0,0" "1189,841")
  (COMMAND "GRID" "ON")
  (COMMAND "ZOOM" "E")
  (COMMAND "LAYER" "MAKE" "_VPORT" "")
  (COMMAND "VPORTS" "0,0" "1189,841")
  (COMMAND ".MSPACE" "ZOOM" "E")
  (COMMAND "ZOOM" "1/100XP" ".PSPACE")
  (COMMAND "REGENALL")

  ;;PLOT SETTINGS
  (COMMAND "-PLOT"     "Y"           "LAYOUT1"

       "NO"         "YES"           "NO"
      )

  ;; LOCK VPORT

  (COMMAND "LAYER" "SET" "0" "FREEZE" "_VPORT" "LOCK" "_VPORT" "")

;; END DEFUN

It's fairly basic for CAD programing, but I'm getting there oh so slowly if you don't hear from me it's because I'm 'Lost In Stupid Parentheses'
