Help creating threads

otaolafr

hello, I am trying to create BSPP threads, to be exactly G1/2 and G1/4
my issue is that if i create with the exact dimensions i get an error when i do the sweep, I know that I is because it shares one point in each turn of the helix, but I do not understand how can I do it respecting the thread dimensions here is what i am trying to do:

 and here are the dimensions I found for the BSPP threads:

EDIT: i solved by giving the number of turns in the helix and not the pinch of the thread. hope helps someone
best regards, franco

I am not able to access your model.

as I saw, you solved by yourself, didn’t you?

more or less, but at least i have found what was the problem in my workflow, it was that I was sweeping a triangle with rounded points so when doing the sweeping i was having a single line shared by the two triangles from different turns.

Hi,
I'm trying to do a symbolic BSPP thread on a hole, however I don't know how to make it.
Does the software has an option on the hole command for tapped holes? I seem to see only ISO, ANSI, DIN and PEM?

Thanks
