How to add holes in one part to line up with holes in another part

[johnAMKDR]

I have an imported model with threaded holes. Call that part "UpperBlock". I want to attach it to another part, "BasePlate". I have added axes to the holes in the UpperBlock and made them long enough to go through the BasePlate and have positioned the two parts as required.

I would like to add countersunk clearance holes from the backside of the BasePlate, but I cannot get the hole function to snap to the intersection of an axis and the face. I thought it worked sometimes, but on inspection, the holes aren't lined up.

The file for this example is attached; thanks for any suggestions.

I would use a sketch and Extrude:

You do this my projecting, an existing sketch or feature, into a new sketch.  I also showed you how to create a new component by dragging existing sketches, which brings the associated body, into it.  This can easily be done early in a model before dependencies develop.  I will not return the model as it is a simple operation to follow.

Trumped my by 27 seconds!

Thanks John. I just projected the axis so it would be easier to use the Hole function should I want a smaller hole in that body ( like flipping which part has threads).

It wasn't as bad as I feared.

As I showed in the video, I would create a component of the body and sketch before adding the holes.
