Lisp to Size Pipes

[107199]

hi,

is there is any ideas how to make lisp with these steps:

1-find all text contain "L/S"

2-copy all these text "350mm" up

3-replace these text each with "pipe size" which depend on the flow "L/S" according to table in attached photo with suffix "mm"

this picture for the final output

It seems like it should be possible with a fairly simple routine. Is that an AutoCAD table or OLEObject? Post a drawing.

What if the L/S value doesn't match anything in the table? (eg. 0.063 Vs)

Hi,

Actually it should be less or equal:

(defun pipesize (lps / ps)
 (vl-some
 '(lambda (v) (and (<= lps (car v)) (setq ps (cadr v))))
 '((0.3 20) (0.57 25) (1.21 32)))
 ps)

 OP, just add the rest of your table as per my adds in the above sub-function.

Looks like a dynamic block with a LOOKUP linked
to a Visible State would do the trick.

The L/S shown in the screen capture has values that
are not showing in the table.
"< 0.30"
"< 0.57"
"< 1.21"
... seem to be the appropriate Lookup display.

My question would be:
Are L/S values fixed?

If not, include an attribute in the block for L/S?
