Hello!
I am learning catia using various notes and drawing mechanical details.
with one of these I found difficulty.
1 do not know how to draw the r 100 and r60 arches highlighted in the attached design
2 this piece is as if it were made up of two plates: 2mm thick and the other 10mm thick.
I should make the two plates separately and then assemble them or there is some other method.
from the same sketch can create two, remaining in the same part?

Sorry for ignorance

if I had to draw it I do everything in the same part......... wanting in 2 different bodi and then joined, but also very well in one body.........

As far as the arches are concerned, I feel normal tangences...

 

[mcbramby]

Unfortunately, we do not see the odds well, I created the body of the file you posted ..... more or less should be like this.
I did it with the v5 r19, give an eye and if you have questions ask .:wink:

of course you can get to the same solution also in other ways......

From my point of view ignorance is always related to the experience that one does.

now we come you have problems:
in part you have answered yourself, if you know that the detail is rigged by two parts is an elemeto of together then models the two parts, and you make the assemblies (bottom-up method) or you start a set and models contextualmete the parts (top-down).
if the final paricular is a unique part this must be modeled in a single part (inside you can model sequentially or in multi-body).
the choice depends on the type of piece, it is up to you to choose.
for the rays if you find yourself in difficulty when creating the sketches do not make the cuves but only the broken ones, and once created the solid creates solid fittings, it is not the fastest procedure but helps you to learn to simplify the profiles (if you see the quotation of the piece very often the centers are listed), then by hand perfections the technique.

Hi.

 

[Aranciameccanica]

first of all thanks to the answers:smile:

ferrezio ok the particular final is a unique part and therefore the model in a single part.

So it seemed to me to understand that if I model the two plates separately (in two parts) and then the assemblies do not become a single piece while if I realize them (as body) in the same part they become a whole right?

which means modeling sequentially and in multi-body?

mcbramby I can't see the body you made because I have version 14:redface:

But you have not answered my question... you have lost points:biggrin:
Once the full sketch is done, could I, with some command, split this sketch into two sketches and then extrude them separately?

Thanks again, I'd like to have some help.

ok questo lo hai capito ....So it seemed to me to understand that if I model the two plates separately (in two parts) and then the assemblies do not become a single piece while if I realize them (as body) in the same part they become a whole right?
It's fair, in this case you don't want to do two separate parts........ .which means modeling sequentially and in multi-body?
practically your piece consists of 2 pads (sp10) and (sp2) if I lyricrei below
the same body you have the sequential if you do it in 2 different body you have the multi-body............. .mcbramby I can't see the body you made because I have version 14:redface:
I'm sorry you could see the sequential and the resolution of the rays you couldn't do, that cmq as I told you were simple tangences......But you have not answered my question... you have lost points:biggrin:
Once the full sketch is done, could I, with some command, split this sketch into two sketches and then extrude them separately?
There is a command in the pad and in the pocket that allows you to make tashes or pads divesi from the same sketch, I never used it and if you want a dispassionate advice more you do the simple and less messed things you have......... so in your case 2 separate sketches that obviously the parts in common will be listed only on the first sketch and on the second you will make coincidences on the other geometry............

summing up the part workbench, drawing the sketch of the pier of 10 mm and extruding it. then design the other part of the sketch and extrude it. Is there anything else?

How do you create a new body?
what are the advantages of multi-body and sequential?


I have another problem. when I do the full sketch analysis tells me that it is open but I do not understand why.
I'll get you the sketch file, so maybe if you have time to give him an eye and tell me the mistake and all the things that are to be improved in my sketch.

here is the sketch file:biggrin:

here is the sketch file:biggrin:

cmq as I told you in the previous post ... pity that you can't open my file so you saw something ................ .

returning to your work ................... .

the sketch is completely free, and it is understood by the fact that the geometry inside the sketch is white, the sketch must be completely green.... (white or green you see it by editing the sketch xthat once it comes out of the sketch workbanch the sketch is always white, unless you change the color) ...................................................... .
you have to study, with maybe sketches + easy, how to use the costrain ...... I have seen a straight that had no horizontality constrain (h ) , you do not have to allow caia to misinterpret something so simple ... if a straight has to be horizontal you have to tell it if by chance it did not automatically take the direction constrain as well as the tangences etc. etc.

Your sketch is not only open, but you have straights to overcome........

cmq opening problems and surmount you see them being out of the sketch because there are where there is the problem of black dots................... .

you then did both sp10 and sp2 in the same sketch............ .

cmq tries to turn in the forum there are so many interesting things , even on youtube.com you can look for cat movies ..................

Have fun:finger:
