Problem with drilling assistant, taps → representations of the SW2018 automatic thread

3D Design Volume Model

Hello everyone ,

I have a small problem on several holes made with the drilling assistant on SW2018.

I noticed when I was drawing my part that the thread was upside down (the selected edge is in the bottom of the hole and not at the inlet), and this, on several sizes of tapping holes (1/8 27 NPSM, or 3/8 24 UNF or 1/4 28 UNF).

I tried to reverse the direction with the double arrow, but that's not the problem because the software doesn't do the drilling because there is no material in the other direction. (see below)

Thank you in advance to all those who will enlighten me!

Hello

Can you post the piece I'm looking at if there is a rational explanation.

Kind regards

Hello

I have the impression on the 1st image that the edge selected as the beginning of the tapping is the one at the bottom of the hole,

Try to edit the "Thread representation" function present in your build shaft and check that the selected edge is the one at the top of your hole.
