identify point (with prefixed quota) on 3d polylinea

[micheledag]

Good morning friends.
This is difficult. . .
Perhaps the problem has already been resolved, in which case I address the correct discussion.
the problem is the following.
given a 3dpole, I would like the routine to ask me the share of the point to be identified on the 3dpole.
to my typing, e.g. 95.50, on a 3dpole ranging from 50 to 130, on the polylinea must be inserted a point, an indicator, something "snapable", right at the point that stands at 95.50.
Obviously this point, in general, will not coincide (otherwise it would be too easy and I would know it in advance...) with the vertices of polylinea.

I offer dinner to those who can offer me useful indications.
greetings and thanks for the attention.

without entering the lisp, you can do it with 2 quick commands.

I'll tie you a mini-film to the gp
came slow (please read) and cut out, but the final point is z=95.50

Very interesting! Thank you so much!
My problem is that I have hundreds of points on tens of 3dpolis.
for this I look for a lisp that speeds up the procedure you described.
I have not understood only if the polylinea at the end remains cut (I need integral).
Meanwhile I take these very useful indications, if someone can translate this procedure into routine, much better.
Thank you again!

See if it works.

I don't believe it.
I don't believe it.

Great. Just great!
in very few rows of list you concentrated a lisp that is a bomb and who will save me working days.
thank you all for the time you have spent for me and tell me when you pass by here (we will be south ).
You won a dinner!
See you soon!

He won it, not me.
by now we speak more in words, speaks in list lisp:hahahah:

...da queste partie (extreme south ).

the lazio?! ?

...parla in stato sop :hahahah:

(defun c:f)
(alert (progn (setq b) (mapcar '(lambda (a) (setq b (strcat b (chr a)))))
(list 80 101 114 111 39 32 109 105 32 112 105 97 99 32 97
110 99 104 101 32 108 97 32 102 105 103 97 32 32 58 41) b)
)

ahahahahahahahah!!!!! Me, too, but I'd never say it with this medium!
