Hello guys
Have problem with combine cut operation.It shows error like the bodies doesn't interact with each other.but the bodies are clearly interact with each other and in the interference analysis also says no interference detected I some how splited the bodies finer and then i got stuck here i couldn't do the combine cut Here I attached one of the portion of my model I need to cut the component (Main (3)(1)) with component 2 and also with component 3. I searched these kind of issues in forums most of the people were saying like it is mainly because of radius, i cant able to delete the radius too.
kindly see the images for reference i highlighted the portion which need to cut with red color.

Please attach a model with a timeline and explain what the overall goal of the design is.
The geometry of that "ring" part is pretty much junk and even if by some coincidence this will combine, it will likely cause further problems down the line.

The above file is the one which you have asked for.
Many Thanks

To be honest, looking through the timeline I done;t have a clue what you are trying to achieve with this desing is and what your overall goal is.
Can you explain that ?

Hello peter,
Actually we are trying to do a mold for this core,for that we need a master pattern,to make a master pattern we need that core to be cut with main body so that I can make my master pattern and using this I can able to produce cores in large level. this is a secondary level. Once the core body is cut with main body I can able to create a cam program out of it.
I hope you understand .
Thanks

To be honest, I doubt your modeling techniques, or Fusion 360 as a tool are going to get you where you want to be.
If done properly, e.g. if split lines are to be maintained etc. this is usually not done with solid modeling techniques but with surfacing techniques and for that Fusion 360 is not really the right tool.
A friend of mine is a very skilled tool and die maker and he works almost exclusively with surfacing.

It is like we are pushing the limits of the fusion 360. I like fusion 360 especially in core and cavity making design because of the simple work procedure and we can make the core and core box easily with out any error for some difficult model than other software. It cannot be say we cannot do it in fusion if you think doing core and cavity in fusion is difficult or impossible then watch this video. I bet any other software cant do better than this and even you can do CAM from this model itself. My question is not that my model is clearly intersecting with the core body why the analysis interference analysis showing no interference.

I did not say that mold and cavity making is generally difficult in Fusiosn 360.
It obviously is more difficult in this case, otherwise you would not have asked for help.
So far you have employed mostly solid modeling techniques and have been successful with it. However now that you are encountering problems it's time to start understanding what is going on in the engine compartment of the tool you are working with.
Please create a screencast of the tri-spoke model and so I can see at what point in your timeline you are encountering this problem.

Is this the geometry you are trying to create ?

Yeah exactly that's what i want. Which software did you used to do that?

Accepted solution
The software is ZW3D, however, with your unmodified model it also created a similar error message but it is much more informative about the error in your model and highlights the problem areas in the viewport.
That then informed my next step.
That next step can also accomplished with Fusion 360.
The problem area in your model is that blue highlighted edge. You did not directly use that edge for modeling, but approximated it using a slice and sketch technique. This what I was referring to as inappropriate modeling technique and where surfacing might be a better approach. When you create the core, the outer surface of the core is nearly coincident - but not perfectly coincident - with that edge and that is exactly the reason the combine-cut fails.
In the screencast I am going through some steps to offset the cone surface outward by 0.5mm to move it away from that edge. This is a workaround that will also work in Fusion 360:

You did a wonderful job peter thanks for helping me out.Actually the model we got it from our customer so maybe kind of issue with the neutral format.
Again Thanks a Lot!!

No, because in order to get this model into ZW3D I also had to export it into STEP format, which is a CAD agnostic neutral format.
