what is the symbol?

[Guido]

Hello everyone,

Can you tell me what the visible symbol in the annex, present on a mechanical design?

I believe you indicate the share from the center/axis component, but I'm not sure.

Thank you.

center line, usually indicates the product flow line in continuous machines.

I don't know.

 

[Exatem]

for us, in addition to what is said hunting, could indicate 690mm from the construction line.

 

[stefanobruno]

distance from the reference line (usually a line axis )

 

[Fulvio Romano]

as mentioned, it is the distance from the center line. but the center line must be indicated on the design, so there is no doubt about interpretation.

Hello exa.... .
is used in naval
to indicate the distance from the ship center line
690 if not erro is (I'm out of a lot in the industry) is an interasse
between the orders of a ship
is the most frequent one
less used and 720-750
enlighten us!

hi shi, a hug to you too.
with the lc symbol, we indicate precisely the line of construction that often, but not always, corresponds to the line of the keel.
In my case, the most common order range is 600mm for surface ships, and 500-475 for submarines. but then we have ships with an oxage range equal to 625, 700... In short, you have to see the type of ship, the "operational needs", the very area of the ship. the interval may not be uniform throughout the hull.
but in this case he may be hunting reason. being a mechanical and non-shipping design, should indicate the distance from the center line

I assure you that mechanic comes from the ship
(or at least came if you see the attachment and handwritten and the sheet was used in the 50-60s
there are precise termologies for each sector
a mechanic says 690mm from the axis
while to differentiate the air force say from the "net dream"
but in this sector we must be enlightened by the President
Thank you very much

Let's wait for me to drive some indication. . .

I mean you say it's lc and not cl? the two letters are superimposed... how do you understand?
in fact the line of construction is usually the keel (profile view), the center line, however also used in the naval field is the line of half-work (planned view) (ok, coincide, but only for bad luck :smile

as exatem says, it depends on the ship. on the smaller ships the ordered can also be much closer.

However, the type of design must also be distinguished. in a building plan, typically divides into a given number the length between the perpendiculars, so the distance between the ordered can also be a number with the comma.

on a constructive design instead, it is advisable to place orders in a rational way to simplify for example the installation of the chairs.

I said that "may" indicate the construction line.
Since it was often indicated (now it is a bit in disuse) with the two overlapping letters as in the annex, I felt it possible.
But I drive it defined a mechanical design and this gives me doubt.
coming to the orders, if they are "study", you divide the llpp into equal parts (usually 20) and therefore can come a non-full number as you rightly said.
in the construction phase instead, the distance between the ordered "real" is resulting in the structural dimensioning of the ship. therefore thrust diagrams, separate weights, applied loads (e.g. engines, flight bridge etc. etc.) will determine the quotas.

Hello fulvio
translate
l c = center line
c l = center line
It seems to me that the second is a "anglosassone" moment

I have seen almost always bl, i.e. English terminology.
building line or
base line
this according to the interpretation given by one or another, however always bl was.
and always, for what little I remember, referred to the keel.

Hi.

Of course.
but on the drawings of the Italian yards, it is written lc.
I could post dozens.

Probably a mechanic, who comes from the ship then... Yes perhaps, but it is not said, I attach an example file, it is a particular.
it corresponds to all the features mentioned by you, handwritten, 60 years etc. etc. etc.
but as you see non is a mechanic or a naval one, indeed, it is a civilian.
I have highlighted the writing in question....... and I apologize for the bad quality, but time has done its course.
Hi.

 

[numero1]

Of course.

I can't post tens, but definitely at least 1 yes.
and it is an Italian yard, the shipowning company is Italian too, and the project has been made by an Italian to what it is.
but on the design it says bl, unfortunately I don't have the file I should scan it first, but I can't do it (I don't have the scanner), trust the word.

Hi.

Then!
Let's stop doing this.
I didn't say that bl didn't mean the same. also fincantieri on the drawings of some of its units indicates the line of construction with bl.
I said that "on the drawings of the Italian yards, lc is written.", especially if we talk about a table of the 60s, and try to say that it is not so.

You want me to let you do a permit to come to our archive and show you over 10,000 tables of this kind?
but do we stop obsessing to always contradict everything and anyway?

Me! I'll come. (look at the raised hand "sbanding"):biggrin:.

Anyway,
even in "normal" mechanics it is used (and was standard) to appoint the half-axis of a particular symmetric with the cl (center line or center line is the same).
the quota in question should refer to the distance from that axis.. somewhere in the table there should be an axis as well "noted" with that symbol (but for a symmetrical/specular piece it is not necessary, it is obvious that we talk about the line of halfway).

... I confirm, I use the center line to indicate the main axis of an object/axieme is also inside as a symbol of the various cad ... what I do not understand is the meaning of the "a" , perhaps to it is the indication to a detail, a note or a reference fee called/a to which it must be 690 from the cl.
Bye-bye.

But why do you get angry? non You said that bl doesn't have the same meaning as lc, I didn't contest it.
the yard then was that.
Still don't worry, you're right, okay.
Hi.

p.s.
no thanks I don't come to your archive, I believe you on the word
