Does anyone know how to make BSPP and BSPT threads on 3D model by SW?
You should be fine Yan, it looks as if they are one in the same.
Yan, to answer your question I don't know of any way to change the taper on the modeled NPT threads. I would venture a guess that you could model the tapered hole and add thread using the thread feature tool but we have not gone that route.
We only do them as a cosmetic thread. We have had multiple issues with modeling NPT threads and have moved to only representing them as cosmetic. As you well know the primary difference is the taper changes from 60° (NPT) to 55° (BSP) but the bigger issue is proper fitment (at least at our shop) at assembly.
It depends whether the thread is internal or external. If internal, change the hole settings from straight tap to tapered tap and select BSI as the standard.
Are you trying to model the actual thread as opposed to showing cosmetic threads?
I did the way as you said for internal tapered hole, but it shows 1/8 Rc Tapped Hole, not 1/8 BSPT tapped hole.
Do you know how to make 1/8 BSPT internal tapered hole?
Thank you very much.
Thank you very much for your help!
Yea, as John Pesaturo mentioned, they are the same. It is similar to how they refer to a size as x"G for BSPP.
Good find Stavros, I didn't even know that was a selection.
How would you make external BSPP threads using Hole Wizard Thread command?
create the body that you want to apply the thread using the major diameter. Then select the Insert menu-->Annotations-->Cosmetic thread. Select BSI and Straight pipe tapped thread and make selections for size and thread length.
Edit: When you get to the drawing, right click on the line representing the minor diameter and select "Insert Callout".
Thanks for the help Stavros.
