Need help locating holes

[Greyhound101]

I'm having trouble locating holes from one part to another. For example, I have modeled one part (part A) that has thru holes. I've brought this part into an assembly and mated it with another part (part B). I want to locate the holes from part A to part B so I can cut and tap the holes into part B. How do I do this without having to measure part A for hole centers and then go into part B to cut the holes? What is the easiest way to do this?

You'll get a couple of different takes on this, but here's what I'd do:
While in the assembly, click on part B and then click on the 'Edit Component' button. Make sure the 'No External References' button is on as well. Click on the face of part B that needs the holes and sketch away using the holes on part A as reference. It's just like editing a part by itself, you're just within the assembly.

You can easily edit a part in the context of assembly just for the purpose you desire. Edit B from within the assy. Pick the face of B for the tapped holes and then pick the hole wizard, size, etc. Locate the centers of the holes to the center of B's holes by pausing on the edge of the hole. You'll see the center of the hole temporarily marked for you to make a point coincident. Once you complete your holes and go back to the assy you should have the holes you desire.

One word of advice, once you have the tapped holes located in B it is good practice to edit the points and break the in-context relationships.

Sometimes I have trouble dealing with the visuals of editing a part within an assembly. Two techniques help. You can put the holes in the part without being picky about where they are, then do the locating as an edit of the position sketch in the assembly.
Another is to make the two pieces restrained in two axes normal to the mating face, then suppress the face to face mate and move the part out of the way to locate the tapped hole. It is just easier to find the features sometimes.
It helps to be consistent in locating either tapped holes or clearance holes first.

In part A, start a new sketch on the face with the holes and create a point at the center of each one. Then save the points you created as a BLOCK. Now go to part B and insert the BLOCK on the face where you want the new holes and use the points for reference with the hole wizard. Hope this helps.
