Hi, I'm a mechanic student, I'm sorry, I'll soon have an exam and I'd need help on two things about sampling, which I don't understand, can I ask?
for example I use the group function--creates complex figure to just close the figure and then the sample but I did not understand how to sample another figure with the same trait (inlcination), I tried holding control but nothing always makes me different traits.(to make you understand better I have to es 3 rectangles one above the other and I want to sample the first and last of the same tract, leaving free that in between)
thanks for availability
 
Guys apologized my question made no sense, because it was enough that I made 45 in both to show that it was the same piece and not that a "line continued in the other".
But I would have a question, which from the slides I don't understand: if you ask me
the pin l must be coupled, with light interference, to a hole: indicate the type of coupling in the system “base tree”.
how do I determine the letters and numbers of the decoupling?so that I have to look at the tables and dimensions of my hole in the drawing but then how do I proceed?

I read the first post but frankly I didn't understand the question anyway I see you solved. in practice it was a no problem.
but also the second question is "dark".
how to determine the letters and numbers of the coupling, is not a problem of microstation.
It is more generally a problem of nominal dimensions, tolerances and couplings i.e., of one of the rules of technical design, whether it is made to the cad, or made with teams and pencils.
you need to study the iso system of tolerances you find on any technical drawing book or on some dispensations among the countless available on the internet such as here:http://www.tecnocentro.it/ita/accoppiamenti/tolleranze.htmbut it's better than before you study a little theory.
Say hi.
 
Hello thanks for the answer.
Yes what I wrote is not a microstation problem but I posted it here since I opened the discussion.
I repeat, I continue not to understand, those tables I also have on the slide. what I don't understand is more than just how to read them because to es k7/h6 because the 7 and 6 from where they are taken exactly?
 
see for example:
the surface of the piece must have a maximum general roughness of 32 m.
the axis of the p hole (passante) has a tolerance of perpendicularity of 0.1 mm compared to the
face h; the hole must have roughness of 0.8 m as a result of processing with removal of material.
the hole is passing and has metric thread.
the hole p must accommodate with slight interference a pin: indicate the type of coupling.


Now you don't know the piece (which are not, for example, dentate wheels or other... more than a set of holes, ribs etc that make up my piece) ok, but it's not important in the sense that I owe from here I must then determine the coupling
 
Look, in my opinion, you're in the right place for microstation, not for the rest.
Let me explain better, we all seek within our limits of time to respond to the best of all questions, but if the question on micro is correct to do it here, since this is the section dedicated to this sw; not the same is the one on tolerances.
In fact I can make the drawing with a sw that is not micro :)
Therefore your second question should be in my opinion posted here:http://www.cad3d.it/forum1/forumdisplay.php?f=108opening another discussion.
or here:http://www.cad3d.it/forum1/forumdisplay.php?f=122Is that clear?

Moreover, generally, it is who has the problem that proposes the solution, or in your case you.
you ask the question where I indicated, describing your problem (better if with a sketch) and in the end you say I thought to write k7/h6 (or what you thought) because ............. etc.
Don't worry if you wrote a stupid thing, you'll be corrected in case, and you'll understand why what you wanted to write was wrong.
Also there is the network, exatem has already indicated you a link, but surely there are many others, and also on this forum there is the search section (top right), which + of once can save you.
Hi.
 
However the link of exatem seems very nice to me, if I remember well:

nominal value, position, quality

20 h 7

in your case you will not have the nominal value, because you will put it in the drawing quotas, so for example for a hole h7 you will have +0.021 - 0
which then is your tolerance, i.e. 7 is a quality tolerance between +0.021 and 0, I hope I didn't write about.......te.
I'm so regulated, don't ask me how and why it was done so because I don't know.
Hi.
 
Let's make some clarity.
as rightly underlined by number1 it is important to read the few simple rules of the forum.
you presented yourself and this is already something. But there are other simple rules to observe that they seem made specifically to facilitate new users.
- discussions open in the appropriate areas. this for having greater visibility and greater chance of getting exhaustive answers (it is not said that those who use other cad come to read microstation posts).
- any questions must be as detailed as possible and it is better if accompanied by a descrtitive sketch.
- to attach images, drawings and anything else, use the appropriate tool (the symbol of the graphite) and not insert the same directly into the text of the post or, worse, to support external services (type imageshack).
- before asking questions, it's better to be honest that they weren't already asked. there is a search function that does for purpose.
For example, with regard to tolerances, http://www.cad3d.it/forum1/search.php?searchid=1536237, you can find something here.
Last but not least, have a little patience and do not ask the usual question several times. not always on the side of the monitor there is someone with the good answer is ready. sometimes in order to be really helpful, it takes time and desire.

As for the question, not being a moderator of the microstation area, I cannot move it to a more appropriate place. Let's get you an answer.
the processes of processing necessarily involve errors for which it is impossible to realize the piece strictly respecting the theoretical dimensions. a lot will be approached but the dimensions will always remain between two admissible limit dimensions whose difference, is the "tolerance".
the iso system indicates tolerances and types of coupling. for simplicity refers to cylindrical pieces (albers or holes) but are applicable to pieces of any form. therefore will indicate the size between two parallel faces of any piece.
looking for you internet will be possible to find publications that explain also with figures, the theory of the system of tolerances.
 
I'm sorry if I'm here, but I have a serious problem.
I have a score of 190*277 use a vertical a4 how do I use the fence command type element(inside) to enclose the print area? I closed the team creating a complex figure but when the seleziono always tells me to select alement. . .
 
Well, here you see it would have been better to open another discussion, because it is true that it is a micro problem, but it has nothing to do with sampling or tolerances.
Forgive us if we are a little pale, but it is to try to keep the forum in order.

However the a4 format is 210 / 297 so you leave some space (justly) between the square and the edge of the sheet, which you want to print vertically.
Everything ok here.......
Well if it's okay then I say that you can make a fence as a devil you want small, big, simple, complex, then when you want to print it with the fence command take a fence that takes all your print area, then file>print> and where there's the voice area choose fence, indeed in version 8i it seems to me to take it automatically.
Maybe you do the opposite, first give the press command and then try to create the fence?
Is that so?
What version of microstation do you use?
Hi.
 
hello it gives you automatic
I created the square with a rectangle
so already closed figure, then inside element fende and mold...on print
I set scale 1 size 190x277e origin 10 10 only
that leaves more space
where c and cartiglio is not perfectly
centered and the tick in center image is..la
v8i anyway

Hi.
you have the rectangle from 210x270, select the fence command and click at the same time either with the sn button or ds of the mouse, "agganci" the fence at a corner of the rectangle (it is better to have the mode of catch ticked on "key point") then drag the fence to the opposite corner and click again with both keys.
then confirm with the sn button.
Now select the press command and preview your rectangle ready for printing.
the rest is about the printer settings but I hope it is a step already made.
 
Hello, then I solved thank you very much for the help. here you can close, now I have to understand well the question of couplings.
Thank you.
