Unable to split body - Same methodology worked on other projects

Hello,

 

Not sure what is different this time around and preventing the split. The idea on the two models is to split the structure with the internal face of the skin.

 

On the success file example, that I did in the past, splitting the structure with the internal skin face works perfectly. Not on the negative example. 

 

Don't even know what is going on as Fusion complains there is no intersection between target and splitting tool..? 

 

How do I fix this?

 

Thank you for your helpSplit.JPG

Did you want to split the Structure body using the Skin body as a tool in the Negative model?  That seemed to work for me, although I'm not sure what result you were trying to get:

Thank you.

 

It wasn't what I was trying to do. Take a look at the video where I split the positive sample then try the same technique on the negative.

 

The tool is the inner face of the skin.

Fir beginners woking in direct modeling mode is not recommended, because it makes it difficult to figure out design intent and to find where things in a workflow might have gone wrong.

Anyway, where is a screencast showing how this can be split:

Yes. The positive example does split. But why doesn't it work on the negative? See my video.

 

Thank you.

Assuming you want to do the same thing and split the Structure wit the inner surface of the Skin, in order to split that the skin surface e needs to be extended upward. Either manually, or automatically.

 

That, however does not work. Likely because your geometry is bad. I already have mentioned the the upper and lower edges of the skin have curvature problems. I don't know how you've creates that geometry but I'd redo it.

 

The image shows a manually extended upper skin surface. The problems are clearly visible.

I created two sketches then did a loft between the two. I went to the patch environment and deleted the top and bottom surfaces creating the empty skin shell from the solid. Then I thickened the surface to the thickness I needed.

 

Not a good approach?

 

Thanks for sharing your knowledge.

Totally got it. Took a while but I understand now. Take a look at the video. Just creating a slicing border solved everything.

 

On the other issue, I am not sure where the weird geometry came from. The loft obviously created some inconsistencies I did not notice before. Appreciated your input.
