There has been some discussion on panel sizing recently. I didn't know it
was a issue still. Anyway, I wrote a Lotus 123 progam in 87 (had an 11/87
file date till today) that calculates the optimum panel size for panel based
on some standard sheet sizes and does both military and commercial. It was
a pretty complicated program, actually generated a quotation. I wrote this
for a customer who is long out of business and out of the business so I'll
pass it out if someone wants it. The prices are a bit dated, probably too
high =8-0, but you can take the protection off and rework whatever you want.
Send me a direct e-mail at [log in to unmask] and I'll send it to you. This
is copywrited and I don't expect to see a version advertised for sale in
Circuitree or PC Fab! It's not that great...
Here are a couple of pages from it.
>>>>>>>>>This is the help section (not much but this was 10 years ago),<<<<<
THIS IS THE HELP AREA. TO RETURN HERE FOR INSTRUCTIONS FROM ANYWERE ELSE IN
THE PROGRAM, PRESS THE {ALT} AND THE {M} KEYS AT THE SAME TIME. {ALT M} THEN
ENTER {HELP} AT THE COMMAND PROMT (TOP OF SCREEN) (DO NOT TYPE THE {} BRACKETS)
TO MOVE THE CURSOR AROUND, USE THE ARROW KEYS TO MOVE THE DIRECTION YOU WANT
TO GO. THE ARROW KEY ALSO ACTS AS AN ENTER (OR CARRIAGE RETURN) TO ENTER DATA.
TO BEGIN THE PROGRAM PRESS {ALT M} THEN TYPE {BEGIN} WHICH WILL PLACE THE
CURSOR AT THE BEGINNING OF THE ENTRY DATA FILE. MOST OF THE WRITING YOU SEE ON
THE SCREEN IS PROTECTED AND IS NOT EASILY CHANGED. ALL DATA IS ENTERED IN
COLUMN
B, EXCEPT WHERE PROTECTED. PROTECTED ROWS HAVE THE WORD "AUTOMATIC IN
COLUMN "C"
MEANING THAT THIS IS AN AUTOMATIC CALCULATION.
ERROR MESSAGES AND SEE ENGINEERING MESSAGES ARE DISPLAYED IF YOU MAKE AN IN-
CORRECT ENTRY. THE MOST COMMON ERRORS WILL RESULT FROM MIS-ENTERING
INFORMATION.
PLEASE CHECK YOUR ENTRIES IF YOU GET AN ERROR MESSAGE.
THE PROGRAM SELECTES THE OPTIMUM PANEL SIZE FROM THOSE AVALILABLE. THE PROGRAM
SELECTS ON A BASIS OF SQUARE FOOTAGE OF MATERIAL WASTED FOR THE ENTIRE ORDER.
SOMETIMES IT MAY NOT BE DESIRABLE TO RUN LARGE PANELS. WHEN {ALT S} IS PRESSED,
YOU WILL SEE A TABLE TO THE RIGHT AND THE CURSOR UNDER THE OPTIMUM PANEL SIZE.
THE TABLE LISTS THE NUMBER OF BOARDS/PANEL AND THE AMOUNT OF SQUARE FOOTAGE
WASTED
FOR EACH PANEL SIZE. TO SELECT ANOTHER PANEL SIZE, PLACE THE CURSOR UNDER THE
OPTIMUM PANEL SIZE AND ENTER THE NUMBER TO THE LEFT OF THE PANEL SIZE YOU WISH
TO PRICE. TO SEE THE NEW PRICEING, PRESS {ALT M}{DETAIL}
{DETAIL} VIEWS THE FINAL FORM WHICH IS PRINTED OUT WHEN YOU SELECT {PRINT}.
NOTHING CAN BE CHANGED ON THIS FORM EXCEPT BY REENTERING IN THE DATA ENTRY FILE
