highlighting quotas that can deceive

[x11start]

a few weeks ago I delivered a production card of a prefabricated panel, on which there was a hole to be made at 99 cm from the edge ... but the worker placed it at 66 cm!
is a fairly common problem for those (like us prefabricated designers), working in cm ...
for this I made a lisp that checks all quotas "dubbie": i.e. those containing n. 6 8 9 and 0, which may be read on the contrary.
the lisp allows you to underline them, or write the value of the subform of text (e.g. eight hundred and ninety-six).
is also possible, with the command [R]clean the underliness or texts. of course in case a quota is drawn, it will be necessary to relaunch the command: Let's say that quota 99 is stretched by 1 cm, relaunching the command (which is now worth 100) would no longer be underlined.
you can choose to check (and underline) only a part of the quotas, or select all the drawing. the odds that have been varied are counted and you can easily locate them by clicking in a blank point of the design: from that point they will leave lines, just to identify more easily the odds found.

attached there are 2 files: 6890.lsp (the main lisp) and gword.lsp (a simple external lisp for the command getkword) the latter must be in the same folder of the main file or in any case in the path recognized by autocad.

I hope you could help!

Meraviglioso, bravissio @x11start always prodigal to share; I'm almost sorry I don't use more autocads to vent this bean.

special lisp, excellent programming exercise, but...
without anything to remove to x11 and for God's love can be a useful lisp, but it is the first time I feel that a quotated measure is reversed. This makes me think of the way the drawings are quoted and the ignorance of those who read them.
the problem is always solved if the quota line is inserted. the measure remains above the line between the notches and this indicates automatically the reading direction.
autocad quotation is normally oriented according to the standard convention, so read from left to right or from bottom up.
autocad provides to guide the text of the quota in order to always respect this international convention.
the most critical quota is the last right, but the line between the arrows makes you understand how to read it.
so who reads the drawing, to reverse the figure, is really "de coccio".
then it is also true that it stands at the designer (it is his craft) intercept the graphic criticalities and make the design readable to the recipient.
my drawing prof., said that the task of who draws is to guide the eye of who will read the drawing. so, while remaining the ignorance of those who read, it is a bit the designer's fault if the measure has been reversed.

you are perfectly crystal right: I share to 100 % what you write (not to 99% or someone could read 66%! I have worked in various companies and everywhere it tends to justify in any way the error of the worker, turning the blame on the designer; So I always want to look for strategies to "protect myself."

Now I understand the need, and what to say... I'm sorry.
However, as a personal advice, I would go down heavy with the wrong person and who tilts the error on you.
but not to get the "cazziatone" to them, only to make sure that next time, before giving air to the mouth, they look at the facts. That is, I mean that the thought arises automatically "we see well before we're wrong, otherwise you know what the guy is, he throws all over us."
For the record, I only use quotas in cm like yours and I tree ugly (educated but equivalent to a dick on the gums), even with people of a certain "weight" if you allow to question what I write.
and I give you a practical example.
I designed a circular plate ø280mm (written both as a quota and as a text in a leader), with 6 ø21 holes for 6 m20 backgrounds.
a multinational writes to me and makes me: "But the ø21 holes are mm?"
my seraphic response was "well, if you can get us 6 holes from 21cm, 21m or 21inch, I'll give it back to you at my expense..."
