I recently had a customer in one of my Inventor Essentials classes ask if an angle has to be perpendicular to the face of the part.
I will typically draw a small flat at the desired angle, then drill the hole perpendicular to that face. But that isn’t necessary. Here is one way to do it:
- Start a new sketch on the desired face
- Draw a line to act as the hinge for the angle of the hole
- This also allows the hole to be on a compound angle from existing edges
- Draw a point at the desired hole center
- Fully constrain the sketch
- Create a work plane at an angle to the face through the sketched line
- Create another work plane parallel to another face through the sketched point
- Create a work axis at the intersection of the two work planes
- Create a work point at the intersection of the work axis and the part’s face
- Create the hole, using the On Point option
- Notice that the counterbore is sunk into the part. This needs to be cleared out with another feature, such as an extrusion
- Turn off the visibilities of the sketch, work planes, work axis and work point
- Create a sketch on the face that needs to be cleared out
- Project the face onto the sketch and finish the sketch
- Extrude the cut out
So there are a few more steps to go through than for a hole perpendicular to a face, but sometimes this is exactly what you need.
