technical drawing templates extravaganza

Postby Lazur » Tue Sep 09, 2014 10:44 am

Have been working on drawings that can match the standards of the technical field, so here I'm trying to collect some of those.

technical drawing layout and folding

Postby Lazur » Tue Sep 09, 2014 10:55 am

First, clean sheets of papers, with their folding.


The DIN A series.
(DIN 823, or ISO 216)

ISO 5457 covers the layout, DIN 824 the folding.
Filing holes are a bit off, didn't check before the corresponding standard: ISO 838.
If done correctly, it would cut into the layout as far as I understand it.

The title block is discussed further in ISO 7200.
Confusingly the source I find on it told that it should be 180 mm wide, however that is set to 170 mm in ISO 5457.


Images below are uploaded to openclipart.
The thumbnails displayed here are just scaled down copies of the real thing in their true scales, contained in the svg-s.

And finally only the empty paper templates:

A note on the trimming signs at the corners.
They are set that way in ISO 5457, but actually they can't be used to cut them out clean, so the whole concept was missed I think.
For A3 and A4 paper sizes, no printing mark is necessary at all -regular printers can work straight with those paper sizes, and there are enough place for the bleed.

Lazur, thanks for doing all that hard work so people can just come to this thread and grab the one they need! There should be some way to make this a 'sticky resource' or something. For now I guess I am just going to bookmark it and I recommend that anyone who ever works with print do the same.
Your mind is what you think it is.

technical lettering

Postby Lazur » Sat Sep 13, 2014 2:00 am

Now, getting to the technical lettering:

SVG Image


and a smaller set:

SVG Image



Remember this was first semester's ugly homework, to practice.
Get empty sheets of paper and write something random, with standard letters, however, we didn't even get an example on how those characters looked like.
Good examples of it are missing from the corresponding books describing the in and outs of drafting too.

Why?

Mainly because these standards are to be sold by the ISO and are copyrighted, as well as the previously posted template's standards.
This case, it is covered by the ISO 3098 standard.
If not ordered from the parent ISO, but from national standard organisaions, they can give only a 2bit raster copy of the graphics.

There are many sources out there though, some of them worse, some of them better.
Even some complete ISO copies are out there, guess it's not legal the uploader is doing -could check the original spain standards.
Further searching revealed that there is a public domaim character set available at wikipedia commons by K7.
http://commons.wikimedia.org/wiki/File:ISO3098.svg

If it is needed for a font, there is ISOCPEUR
http://www.azfonts.net/load_font/isocpeur.html

and a more "free" licensed one, OSIfont
http://code.google.com/p/osifont/

or a commercial one, Isonorm
https://www.fontfont.com/fonts/isonorm

all of which differ a bit.


The lettering is based on manual drafting, thus, a Hershey-text kind of aproach is closer to technical needs.
Like, the caps are tweaked on those fonts, to appear "nicer".
And, originally, technical letters were to be drawn with standardised line weights, so the size of the lettering should be strict too.
Set in the mentioned standard.


Why not all the accents?
And greek letters?
And cyrillic?

Because of the lack of good resources.
The original standard is not containing all the accents by the way.

Why not all the four types of standardised lettering?
Because this one is used mostly, and, that italic letters raise geometrical problems.


I have the constant feeling that things cannot be drawn "flawlessly".
Like, in this case, letters in grey are using tangents to circular paths -some inaccuracy should appear no matter what-,
and, letters in yellow are my interpretations.
Those are the "0", "S", and "K" characters.
Having read inkscape 0.91 is having a support for real life units and increased accuracy, these all may be better redrawn sometime anyway.

Hello Lazur,

It takes some time to load all this topic, because there are a lot images, and every time one of them gets loaded, the "position of view" changes.

I suggest to edit this topic, put a sample (or two) images in the first post, and then just put the links to the other images, on the next topics. It's my opinion, maybe others prefer the displaying of the images?

About the copyrights, that is also my concern. Aren't you worried that ISO or DIN could demand your for making public this information?.

I wasn't aware that even the folding of the papers was standarized. Also tht text boxes are ruled?. I have to say that, the most of the times that I've drawn planes, mostly drafts or sketches, I just had picked templates from other drawings, paying little attention to size of letter or location of the objects. Of course there are some conventions that must be taken in consideration, like dashed lines, or location of plant and side views. But other things,... well.
My comments are just for sharing what i have in my mind
It's an excelent and useful work.
If you have problems:
1.- Post a sample (or samples) of your file please.
2.- Please check here:
http://tavmjong.free.fr/INKSCAPE/MANUAL/html/index.html
3.- If you manage to solve your problem, please post here your solution.

If you hover and read the link you will see they are not images but the actual SVG file so in this case the preview and the download are all in one, avoiding confusion and messages like "I can't edit the template" etc. so in thisparticular case I think it's best to leave it this way.
Your mind is what you think it is.

There is always some risk, that law is not having common sense.
But for humanity's sake, it cannot be taken seriously.


Firstly, these are tought by universities, so that all people drafting use the exact same stilistics.
Would that mean, every single people with a technical pen should buy a legal copy of the standards?
These were meant to be used by everyone.
(And unlike autodesk, you don't need to buy a new license to use your ruler.)

Not that it would make any sense if redrawing what's exactly in the license could be considered as a copy.
Imagine you go to the museum, and see the Mona Lisa.
Then without taking a photograph, by having an extraordinary memory you go home and paint the exact same.
Where would you draw the line of copying?
The standards I could get for money are all in raster format -would then a vector redrawing be a copy?

And, finally, these are not what's presented in the standards, it's just something that is meant to be compatible with them.
For example, the template standard ISO 5457 has only one paper size template as an example, has it's lettering not fitting with the lettering standard ISO 3098.
It doesn't mention 2A0 sized papers, so it was all my take on the Ax.00 series.
(Since I found there are 4A0 sized papers mentioned as well. But how could that be made right with this standard? The 2A0 sized paper's rows went from A to X, how can someone go on with that?
Like
A
A, then

A
B and so on?
Because there is no place for two characters next to eachother.)
Also, the filing holes are not taken into consideration in the template, because with it you would cut the line.
(On a side note the paper just tears off, no matter the hole's position...)


There are lettering stencils on the market, like this.
Surely it is based on the standars but is just something that can help the drawing to be standardised with less effort.

(On another side note, before ISO 3098 came in, the DIN 1451 Mittelschrift was used widely.
More legible, but as presented in the original character set, it cannot be reproduced with technical drawing pens to it's fullness, however I do have a lettering stencil for it.
this looks similar, though the various line weight is not a technical solution, nor the uneven line width.
Mittelschrift is a nice lettering by the way -in my humble opinion-, which was used in car licence plates until 2000 in Germany.)


I see what you mean with the slow loading, will consider simply linking most of those embedded, like the rest.
For that matter I will split the last lettering template to each line weight, so that the browser may only render all of what's inside the svg at once.

Here is the set broken down to stroke weights, with black letters.

2 mm


1,4 mm


1 mm


0,7 mm


0,5 mm


0,35 mm


0,25 mm


0,18 mm


0,13 mm



Letters with less than 0,35 mm wide strokes are not legible and should be avoided,
but since those line weights are conventional, I added 0,25 mm. 0,18 mm and 0,13 mm.
(Somewhere mentioned in ISO 128?)

Lazur, have you thought about making the paper size templates available as actual Inkscape document templates? You could make zip files of a whole group of SVG docs (e.g. 2A0-A4). That way, when people download them, they don't have to go to the trouble of making the custom Inkscape template. They just unzip, and put in templates dir. (I realize they're still quite useful as is. I'm just thinking they could be even more convenient.) I'd be glad to make a special album for those on IC -- I mean packages of custom Inkscape doc templates....although.....actually they might be too big, all in 1 file....but we could find a way, if you like.

Maybe the text too, although I'll have to study on the best way to provide them.

Making those to inkscape templates?
Hmm.

The problem is, that the text block should be customized anyway, (and, probably most of the rest deleted as practice may not be totally parallel with the standards -such the cutting marks.)

Another thing, is that people may prefer adding the right format to the drawing at the finish.
"Draw freely", and choose the paper you can print it on after.
(Personally I hardly ever used any other template than the default A4 portrait format to start with.)

I will make a collection of them at openclipart, so people may find it easier.


The lettering may be better boundled into the Hershey text extension.
If there was a complete character set (?) with all the ascents (??).
And someone who actually know how to code it.

In practice the mentioned fonts can suit most of the needs.



Googled up "technical drawing template svg" and this topic was the first after freecad, where svg-s are also available.
For that matter, they are not all compatible with the standards, but still probably being in practice.
Maybe it's just an oddity to draw uniformed?

I think some people may do their drawing and set the page size when finished. I usually do that, because I almost never have a particular goal in mind. What I start out drawing is almost never what I finish drawing. But this is all just a hobby for me.

But I think there are also some people who start out knowing exactly what they want, and finish with what they started to make. For example, someone wants to make an icon set. They might need a 16 x 16 page or 48 x 48, and need to make 50 icons. So it would be convenient for them to start with the page size already set.

Or another example, more relevant. Maybe someone is writing an owner's manual for a tv. They would need standard page size, and also start out knowing what the page size will be in the end.

But anyway, it's just a thought :D

Edit -- I don't have access to the analyitcs for this site. But if you see that the files you put on open clipart are downloaded quite a lot, maybe an indication that custom Inskcape docs would be worth making. Just another thought :mrgreen:

Hmm not sure where all the thumbnails&links gone.
Since there was a server update at openclipart, the url-s may have broken?

Anyway, here is a link for the collection:

I've noticed a lot of your images which are hosted at OCA are missing on Inkscape Community too.

It seems to me like it would be really bad form, for them to break large chunks of links, permanently. Maybe they are working on servers? Or maybe they don't realize it's happened? Maybe you should notify them?

When I click on one of the links above, I see a cartoon of a sad monkey (or something?) that says they can't find what I'm looking for.

That's their default 404 error page. Will report them back.
