Unroll/Flatten/Bent Solid Revolve without using Sheet Metal

[jamieking89]

Is there anyway to Unroll/Flatten/bent a cylindrical model which has been revolved around the x-axis?

My goal is to be able to produce a view of the model in this state in order to clearly show where cross drilled holes intersect certain ports. I have created a simplified version of what I would have modelled with only one intersect as opposed to the typical 10 plus. I have also attached and what I am hoping to produce but without the intersecting cross drill.

 Thanks

Why not use Sheet Metal?

[jamieking89]

If I convert to sheet metal is there another feature that can be used as bend doesn't produce the results I am hoping for? The part I am modelling is in basic form a pipe with porting that falls on different angles at each end? 

I cant seem to figure out how to split the cylinder and unroll it so that all porting will be laid flat. I have no edge to bend the part around.

Any idea?

Thanks

Attach *.ipt file here.

I will then Derive Component as surface body.

Thicken.

Rip.

Flat Pattern.

[jamieking89]

I tried this also but was presented with the error of selected component was rejected since it causes a cyclic dependency.

Hi! The part is a hollow cylinder and there is no gap. Could you tell me how you want to unroll it?

Many thanks!

Hi, why are you trying to perform this operation? It seems more simple and understandable to represent the view in a different way, for example something similar maybe in this way, greetings

[jamieking89]

The reason behind this view I would like to produce is on some of our components we have ports that tie in to each other but aren't always in the same position on the lower and upper faces and their lines cross internall. Therefore I would like a view of the part "unrolled" to be able to check that the correct ports line up with each other at each face. Apologies, my single line example there didn't help in you understanding what my goal was. Please find attached a slightly better model.

Is there anyway of laying the part out this way?

Thanks for your help. 

[jamieking89]

The part is a solid body with holes drilled internally to tie up with opposite end ports.

Do you mean to convert it to surfaces and then flatten?

I am hoping to create a "unrolled" or "flattened view of the cylinder to clearly show what ports match with others at either end of the component. in a way much like deleted faces but laid flat. Apologies my first model was perhaps to simple to ask what I was hoping to achieve so I have attached a slightly better model.

Thanks

This is definitely a step in the right direction, the only thing is I need to show the internals in order to show the cross drilling and through porting. Is this possible? If converted to surfaces it would lose all internals?

Thanks for the video.

[JDMather]

Then instead of deriving a surface - Derive as solid, Rip and Flatten.

[jamieking89]

This is more of a typical shape of the component I am trying to flatten, I tried with your technique but due to their being 3 faces it didn't work and as previously mentioned it didn't include internals.

The 3 face undercut is irrelevant.

You deleted the wrong faces, and you should have set to Heal. (and done the Delete Face in the Derived part)

[jamieking89]

Without being to much of a nuisance, could I ask if you make a video of how you done this with the solid and 3 faces as I found your previous video very helpful.

Thanks

I have been playing around with the 3 faced model as a solid and still cannot seem to rip it.

Can you advise, ideally with a video? Apologies for bothering you again.

Jamie

[JDMather]

Examine Revolution5.

[jamieking89]

I still cant seem to do it once I have corrected those revolutions.

I have followed your original steps with the single facedc cylinder but to no avail.

1. New part

2. dervive part as solid

3. Thicken by 0.004

4. create rip point sketch on top 3rd of model

5. convert to sheet metal and update sheet metal default settings to 0.004 and 1

6. attempt to rip but encounter the error "Creat Sheet Metal Rip: problems encountered while executing this command."

[JDMather]

Almost everything you have written doesn't make logical sense.

Attach your file here.

[jamieking89]

Yeah I am completely lost as to how you managed it on the solid body with 3 faces. Rather than going back and forth (as I have no clue how to get to the final result) you could show me a video of you completing it? I find it easier to follow those. Also perhaps in your reply attach your finished model so I can look at how you have done it there too.

Attached is the part with the holes actually cutting through the material and not as they were before.

Again apologies for my lack of understanding and thanks for your help
