threading indication

[yudansha]

Good evening to all,
I am finishing a solidworks project where there are also some threaded couplings. I modeled the various threaded components in such a way as to say "simplified", without therefore making " cosmetic annotations".
Going now to create 2d tables, I doubt myself...
a quotation, for example, as in the attachments (sections) is to be considered wrong? without cosmetic threads clearly lack the subtle traits of screw and mothervite as standard; but by quotating the nominal diameter with the indication of the thread (or axis) is the same risk to betray strongly the norm?

Thank you.
Edoardo

p.s. My presentation is in the sw section

 

[meccanicamg]

the norm indicates that threads include fine thread sections, whether they are external or internal depending on whether it is hole or threaded shaft. the various modes that swx allows to do are basically for other needs, especially on the minimum hole or maximum hole.

therefore the above indicated representation is wrong both in the first and in the second scheme.

..and is also wrong all the section in itself..:biggrin:
you don't understand what you're looking at, what is that design (of course, you told us and we get there); screws, threaded pins and shafts generally do not dissect.
but also were not that type of elements (therefore selectable) the sectional dot should be oriented in an opposite way between the contiguous bodies.

greetings

Yes, I realize I'm wrong, I try to explain myself better in relation to my case.
as from attachment, I have to couple the threaded stem of a hook (just the stem cut without hook for simplicity) with a relative nut shaped according to some needs (.type the track below, etc.).
At this point, I do not know my modeling is excessively simplistic or wrong, but my problem is to create 2d tables from these models pertinently including of course the thread indications I want for these organs

Thank you.

Thank you.

if you want to see the threads obviously these must be present in the 3d model; What about the program that there's a filet there if you don't tell her?

add them to the parts from the menu insert > annotations > cosmetic thread. follow the property manager and his help, on the table you can make the "parametric" caption appear.

Okay, thanks, Marco, I'm trying to ask you something again. .
Suppose I download the models (static) of a screw and give from these links:
http://www.catalogds.com/db/service...e_2,_metric_fine_pitch_thread&product=inhf202
http://www.catalogds.com/db/service...pitch_thread,_grades_a&b&product=ihsf0201both with nominal diameter 10x1.. .
always with 'insert' - ' Cosmetic annotation', can I apply thread to both static models?

to all models that are native to swx or imported from other formats (stp, iges etc.) you can always apply cosmetic spinning to so-called "albers".

You can also apply the "cosmetic hairstyle" to the hole. if the nut hole is the hole having a minimum diameter you can do with the creation of holes directly the right thread hole, otherwise do an internal extrusion to add material and then do guided drilling.

all this to have the coupling hole / screw with correct representation according to regulations.

 

[sampom]

In fact, for the mothervite you can add a threaded hole with the creation guided on any body, native or imported that it is. in this case I did not propose it because that function comes maximum to a m64 and the model posted is m72.

[yudansha]

In fact I can't use the creation wizard of holes because that function only handles up to m64. Moreover the thread that I preview is round according to one 9471 and therefore the indication must be of type ft72x8.

I then folded on the cosmetic thread by changing the 'dado' to bring the hole to 63.2 (hazel diameter) instead of 72 (nominal diameter); and then I entered the annotation.
the result seems correct now, what do you say?
in any case the image of the coupling (img3) is still wrong (both because I dissected the threaded organ or by the absence of the subtle traits)...but I failed to find an appropriate function on the sw for a correct representation always starting from the model...help! :smile:

Moreover I wonder, the 'interferences' that you come to create ('instruments' - 'relevance interferences') the bypasses simply with a 'ignore'?


Thank you very much!
