filettature gas

[gospel]

Hello.

My company has just passed from solidedge to nx 8.5.
I immediately noticed that gas uni 338 is missing in the threads.
I saw through the online guide how to add custom threads but since it is quite laborious (in terms of time), I wanted to know if someone had already added them and could maybe share them.

Thank you very much.

hello gospel, personally for cylindrical gas fillets use bsp. Can you tell me the differences between bso and 338?

 

[Lorenzo77]

I wanted to write bsp not bso

I wanted to write bsp not bso

bsp threads are English norms expressed in in inches..in Italy and in general in Europe we follow the uni en iso norms expressed in mm, for the gas threads the reference norms are the uni en iso 228-1 for the cylindrical threads, and the iso 7/1 for the rp/rc threads (which normally equate to the cylindrical threads iso 228)

338 is a standard for pipes that differs slightly from previous

I had copied the gas values following those metric in the file nx__/ugi/thread_metric.dat .
this to have in the command threads the possibility to add gas to a hole
the values I have entered are:

gas,0

to change the threaded hole command inside the feature holes (post nx6) I asked info to the helpdesk without success

to change the threaded hole command inside the feature holes (post nx6) I asked info to the helpdesk without success

I managed to modify the holes in nx 8.5/9..c' and a file to open in excel and to fill out. The only thing that's not right is the callouts of the feature parameters command in the drawing environment of nx 8.5, but I think it's a bug because in nx9 they work better than nx 8.5
