Newbie problem with rectangular patterns

[Tall Grass]

Hey guys. I'm quite new to inventor so bear with me because I'm sure there is an easy answer for this. I just can't figure out what it is. As you can see in the attached screen capture there is an assembly. I created a threaded counter-bored hole (1.75" deep) in the bottom-left hand corner of the component (which is 1/2" thick.)

 

Then I used the rectangular pattern to replicate the original counterbore 7 more times. What's strange is that on the right hand side the holes are not displaying properly.. they stop at the component below it. But if I drag the cursor over each of the occurances it highlights the bottom of the hole as well at the top...

 

Where has the middle gone to?

Note 1: Don't put holes in the assembly unless they are drilled in the Assembly. They will not be reflected in your individual parts.

Note 2: If you must do them in the assembly use the Bolted Connection command to create holes that drill down to the part level

Note 3: If you are still insistent on holes at the assembly level; click on the hole and select add participant if they are not going through a part you wish it to.

Thanks for the guidance on this issue. I guess I'll have to rethink how to use inventor.. still fresh enough that it shouldn't be a problem.

Think of it this way.

 

In the real world when you add holes after the parts are assembled (match machining) the parts would not have those holes before assembly.

 

You can edit parts while in an but you need to understand whether your fearures are being added at the part level or assembly level.

okay. I understand your reply and the points you're making about assembly vs part editing and match machining but something about the inventor process still eludes me... why is the hole feature available in the assembly menu?

 

What I'm trying to do is create a threaded hole between two seperate components.. the hole feature is available in the assembly menu so why shouldn't I use it? I understand that even if I use it the individual parts will not reflect those changes... but why not??

 

What would be the best way to create a threaded hole between two steel plates that is threaded and held together by a bolt? should I edit each component... create a hole.. thread each hole.. set a relationship between them somehow and then use the design accelerator to place a bolt? that seems unusually complicated.

becouse sometimes you first assemble the thing your making , and than drill the holes, to be sure there in the right position,
