Can you apply an assembly extrusion to a part?

Team 74 has made a full assembly of our frame and in this assembly we trimed a peice tube with the “cut” extrusion. This was done in the actual assembly not in the part its self.
So my question is this: Can we then apply this extrusion so that it shows up in our part’s drawing?

Thanks

I believe if you edit the piece in the assembly, it will ask you when you save the assembly if you wish to save the parts of the assembly as well, so any changes you made should get saved there if you click yes. I may be wrong, I’m not the best at inventor, but I’m pretty sure.

anyone confirm?

Have you saved the file? Closed everything out? And reopened the drawing?
Sometimes the computer has trouble processing updates in that direction. Try what I mentioned above and then respond back. If that doesn’t work, I will get back with you as soon as I can.

When you sketch the new sketch on the part you dimension the sketch. Then you turn on the visability of the dimensions on on the end of the sketch.

I don’t think that is what he is asking about.

Tip #95 Make sure you know which environment you are working in assembley/part. You must make the cut at the part level if that is where you want it - just like the real world.

An assembly cut extrusion will only show up in the assembly or in a drawing of the assembly.

It will not show up when you open the part or when you make a drawing of the part.

When creating machinery, part drawings are created to manufacture the parts as they appear prior to assembly. An assembly drawing will show the parts assembled and any subsequent modifications that would need to be made AFTER the parts are assembled. For example: it would be common to “drill and pin at assembly” - two or more parts would be assembled (and possibly adjusted) and then pinned in place. The drilled holes would not be shown in the part drawings showing how the parts are manufactured.

This is simple:

When you make the cut extrusion it will appear in the assembly and then when you hit “Save” or “Save as” on the assembly a window should pop up asking you if you want to save changes to the parts. If you click the button “yes to all” on the bottom then click “ok” on top, it should save any changes to the part you made in the assembly to the original part, sketch and all. If you need me to send you pictures i can screenshot this process.

John - an assembly feature will not make changes to individual part files. If you edit a specific part in the context of an assembly by making an extruded cut in the part THAT is different from making an ASSEMBLY feature.

As JD says: Pay attention to where you are making your edits.

It will, if you do it properly. That is one of the advantages of Inventor. It can be finicky though. Sometimes it will do this on it’s own. Sometimes, it will refuse altogether. My suggestion is that if it is refusing, then use the often overlooked copy and paste feature. Just open the sketch for the extrusion you made, select all of the lines/dimensions/anything and right click to copy. Then, create a sketch in the part that is EXACTLY the same as the one in the assembly. Then, simply paste the stuff you copied earlier. Now all you have to do is add the dimensions to constrain the sketch to the part.(Note: It should already be constrained to itself.)

grsnovi: Just because it is not the “right way” of doing something does not make it the “wrong way”, it just makes it a “different way”.

Cutting and pasting the assembly sketch into the part and then creating a PART FEATURE will indeed provide you with a PART FEATURE - which is different from an ASSEMBLY FEATURE.

I am not making any statement about “right” or “wrong” - I was simply stating how features created in Inventor (at the assembly level) work.

I have never seen this behavior - post an example dataset if you can.

Copy and paste is whole 'nother ballgame.

I am a bit unpredictable, I assure you that it works. I might be able to make an example tomorrow, I really don’t know. I am currently cut off from Inventor. (graduated) As soon an I can, I will post some screenshots of me doing this.

Don’t waste your time - I’m just yanking your string. :rolleyes: I am completely familiar with the behavior of how Inventor works. I almost never see any unpredictable behavior and if I do it is generally documented as a bug. If you do find a bug I will happily verify thru reproducing the behavior and support you in getting it reported and fixed. But in this case I am certain there is simply a mis-communication of the problem and the behavior of the software.

I think that’s the case JD. I re-read the whole thread and I believe I may have been part of the problem. I think the OP was simply saying that they had created an assembly feature by mistake - they really wanted a part feature. Along the way various folks seemed to be suggesting that you could somehow get a part feature from an assembly feature. I agree there are ways to recover from going down one road and then backing up to get where you need to go. I probably read the OP’s question more literally than it was intended and possibly others who have chimed in have all been assuming different things as well.

Thanks, I could really use that time for homework, and posting.

Worse comes to worse, just make the cut in the part too, it shouldn’t take that long at all if its just a simple cut :smiley:

This thread is starting to remind of the ‘how many people does it take to screw in a light bulb?’ question. It shouldn’t take 6 of us to solve an extrusion problem.

Mithiasis: Would you post that you fixed the problem? Or that you still need help?

To all: This post is not meant to discourage people from asking for help, I would just like to request that you post when the problem is solved. I personally enjoy helping people use Inventor and would like to encourage anyone with a problem to post it.

You hit the nail on the head there, we did just redo the cut in the part file. Thanks for all the help folks.
