Place simple/countersunk holes on internal surface of cylinder

[DanielatVT]

Hi all,

I have been trying to place simple/countersunk holes on the inner surface of a cylinder. I projected the point from the outside surface and the axis is "normal to face". This approach works in many previous cases but fails this time. I kept getting "the tool and target do not form a complete intersection."

Is there any other approach that allows users to have a countersunk hole on the inside surface of a cylinder?

Are you selecting the inner surface as the face for placing the hole?

Also to help troubleshoot the construction, try using the option to create the tool-body instead of actually creating the hols feature. This might help to give you a hint as to what might be happening.

Hi John,

Yes, I selected the inner surface as the face for placing holes. It is because the countersunk has to start from the inside.

In fact, I just solve this problem by enabling the "Extend Start" from the hole feature setting.

Thanks anyways.
