Cosmetic threads display in drawings

[tleati]

Hallo,

anyone could tell how can I have cosmetic threads in a drawing display with the 45° line at its end? just like indicated in the red circle in the screenshot below:

they display by default without that ending oblique line, and I tried to change the stardards in threads_standards but without success.

thanks

The only way I've ever seen this done is with surfacing - manually creating or modifying the cosmetic thread quilt.

It's hard to tell from the picture, but it almost looks like the geometry itself is cut. Just out of curiosity, what happens what do you see when you hide the cosmetic?

Hi Tom,

thanks for your reply. I really can't believe this software cannot display according to Norms ISO 6410, it would be really incredible!!

The oblique lines "tratto a filetto incompleto" is to indicate the length of the incomplete threads at the end of the thread.

As you ask, when I try to hide the cosmetic thread from the left model tree window, nothing happens, that is the thread does not disappear...it's really strange indeed...

Hi All,

Please set drawing option (.dtl file option) 'thread_standard' as 'std_jis'. this will allow the thread with 45 degree as highligeted in your sketch

Hallo Shreeharsha,

thanks for your reply. The option you wrote about does display it that way but the oblique lines are not 45 degree, as you can see in the below screenshot:

maybe because they rapresent the length of last turns of unusable and incomplete thread, which by experience is slightly lower that 2*p, where p is the pitch. Therefore the longitudinal side of the small triangle is longer than the other and the angle is not 45°.

anyway, it's already good to have it.

Bye
