If a 3D part is tilted, for example it will not be able to view as normal thread hole in 2D.
Procedure:
[1] Place [Block] in space from [Shape] catalog.

[2] Select the tilted part, then launch TriBall.
[3] Hover the cursor over the short central handle of the TriBall (the directional handle), then right-click and select [Perpendicular to Face] from the context menu. ※ Please select to note short handle direction.
[4] Select the face of the block placed earlier. The part will be repositioned so that the directional handle becomes perpendicular to the selected face.
[5] After correcting the tilt, switch to CAXA view. The tap will now be displayed.
