Multiple NPT threads??

Riin · Mar 18, 2004

hello everyone, i am having a problem making multiple NPT threads. i try to make points then holes, but the hole option doesn't have NPT.
i try to make a NPT hole and mirror, i'm not able to mirror threads.
i am currently trying to make a part with 200 npt holes and i really don't want to pick each hole one by one.
if anyone knows how to get around this please let me know.
Thanks, Riin

The hole feature doesn't work for NPT threads. To create these you need to extrude-cut a circular sketch with a taper (NPT is 1° 47'). Then select the thread feature and pick the hole. NPT values will show up.

I use Ifeatures, try the following...

The npt feature is at the bottom - You may need to move the "end of part" to the end in the model tree
