lisp/custom develop for plant 3D total weight

August 4, 2022

Good morning all, i have faced a problem with plant 3D 4 days ago, i want to show the total weight on my isometrics, i know plant 3d can do the weight by item and pipe length, but what i am tryuing to do is show a field on bill of material showing the total weight of that isometric sheet.

I am attaching a copy of what i am trying to do, the blue circle is what i want to come out on my isometrics from plant 3D

Maybe a lisp or a custom build can solve that issue?

Thank you!

Haven't used Plant 3D but looks like you need to calculate length. Then multiply that by the linear weight unit.

A little bit of how I need to proceed to get total weight now, and it take times. maybe a lisp to run after isos created could be helpful

One of the requirements on our spool drawings is to have a total assembly weight shown so that when the spool piece needs to be physically moved around the shop and loaded on a trailer for shipment to the jobsite, the shop personnel can adequately rig the spool piece. As an improvement idea for AutoCAD Plant 3D, I’d like to have this as an option to be added to the Isometric BOM. Presently, I need to individually open each spool drawing after generation and add a line to the BOM table where I can place a formula to sum the individual line item weights and add a description of “WEIGHT TOTAL =” in the adjacent cell. Obviously, this is relatively time consuming and an automated approach would be a huge time saver. I’ve attached a spool dwg showing what the output looks like when manually configured.

I found this code from Mr. lee, but it allows me to pick a block, my intention is to pick the excel table that comes out when i run isometrics in plant 3D

and pick the field where weight is shown and sum those values...

;;  This program allows the user to sum numerical attribute values      ;;
;;  held by a selection of block references, with the results displayed ;;
;;  in an AutoCAD table.                                                ;;
;;                                                                      ;;
;;  Upon issuing the command syntax 'attsum' at the AutoCAD             ;;
;;  command-line, the user is first prompted to make a selection of     ;;
;;  attributed blocks to process. This selection may include standard   ;;
;;  or dynamic attributed block references.                             ;;
;;                                                                      ;;
;;  Following a valid response, the program will iterate over the       ;;
;;  selection and will sum all numerical attribute values, grouping the ;;
;;  values by common attribute tags.                                    ;;
;;                                                                      ;;
;;  If multiple attribute tags hold numerical values, the user is       ;;
;;  presented with a dialog interface and prompted to select which      ;;
;;  attribute tags should be displayed in the resulting table, before   ;;
;;  being prompted to specify an insertion point for the table.         ;;
;;                                                                      ;;
;;  The program will then automatically construct an AutoCAD table      ;;
;;  with properties inherited from the active Table Style. Each row     ;;
;;  of the table will display an attribute tag alongside the total of   ;;
;;  all numerical values held by that tag in the selection.             ;;
;;                                                                      ;;
;;  If the program is configured to use field expressions in the table, ;;
;;  the various totals will be automatically updated following valid    ;;
;;  modifications to the attribute values referenced by the fields.     ;;
;;  Note that this does not include the addition of new attributed      ;;
;;  blocks to the drawing, or the removal of attributed blocks          ;;
;;  referenced by the table fields.                                     ;;
;;                                                                      ;;
;;  If field expressions are used, the formatting of the results will   ;;
;;  be dependent on the field formatting code set in the program;       ;;
;;  otherwise, the formatting of the totals displayed in the table      ;;
;;  will be dependent on the current unit & precision settings          ;;
;;  (that is, the values held by the LUNITS & LUPREC system variables   ;;
;;  respectively).                                                      ;;

and here something else I've found

(defun C:tw ()
(vl-load-com)
(ssget "_X" '((0 . "ACAD_TABLE")))

)

with the code above I can select the cad table, so now I need to sum the numbers from E3 : E6 and place the result somewhere in my border as a table.

any complements? to help? i am new on that trying to learn lisp...

Thanks all

You can set or get a cell in a table it uses row column but they start at 0 0.

E3
(setq objtable (vlax-ename->vla-object (car  (entsel "Pick table "))))
(setq val (atof (vla-gettext objtable 4 2)))

So do a little loop adding the val's

August 17, 2022

Thanks for the answer, couldn't make it work. i will keep trying the code u gave me. need something with no user interaction, i am trying to load a lisp that can open the dwg and do the selection automatically.

here is the scenarios:

my table has three columns and 6 rows.

Colum A,B,C

ROWS 1,2,3,4,5.6

A1 thru A6 is my pipe length, B1 thru B6 is my pipe weight.

i am trying a lisp that can read B1 thru B6 get the values sum them and return as a small table with the summary results.

it looks so simple when i use the table formulas, but it takes time when you need to go one by one drawings. a lisp could be a solution to make it happens.

Thank you all again!

I have found a solution for now, it needs user interaction but its ok for now, i will keep studying this code to make the same thing code does but without user interaction.

Thanks all of you!

Looks like the table already has the total weight for that row of pipe just need to sum them.

See if this works for you.

Pulls the total number or rows from table and will look at each cell in the weight column. won't error if blank but might error their is something other then numbers are in there.

;;----------------------------------------------------------------------;;
;; SUM TOTAL WEIGHT OF TABLE
(defun C:TW (/ i tol tbl mrow)
  (setq i 2
        tol 0
        tbl (vlax-ename->vla-object (car (entsel "\nSelect Table")))
        mrow (vla-Get-Rows Tbl)
  )
  (vla-getboundingbox tbl 'MinPt 'MaxPt)
  (setq LL (vlax-safearray->list MinPt)
        UR (vlax-safearray->list MaxPt)
        pt (list (car UR) (cadr LL))
        pt (polar pt (/ (* 3 pi) 2) (getvar 'DIMTXT))
  )
  (repeat (- mrow i)
    (if (setq x (distof (vla-gettext tbl i 4)))
      (progn
        (setq tol (+ x tol))
        (setq i (1+ i))
      )
    )
  )
  (entmake 
    (list 
     '(0 . "TEXT") 
      (cons 10  pt) 
      (cons 11  pt) 
      (cons 40 (getvar 'DIMTXT)) 
     '(72 . 2) 
     '(73 . 3) 
      (cons 1 (strcat "TOTAL WEIGHT: "(rtos Tol 2 2)" LB"))
    )
  )
  (princ)
)

Thank you so much, that worked perfect for round numbers. and you are right it doesn't sum when I have for example "9.5" + 2.25 it result in 9 instead 11.75. as you motioned probably because the cell contains a comma.

No i was using atoi to convert cell text to integer. this rounds to the nearest whole number.

will output to ##.## now if you need more decimal places change the following line.

(cons 1 (strcat "TOTAL WEIGHT: "(rtos Tol 2 #)" LB")) ;change # to how many decimal places you want.

Updated code above.
