Help needed with shell command

Hello,

 

I need help with shell command. When i want to shell my product, program gives this error: Shell1: Could not build this Shell. The attempted Shell operation had non-manifold inputs. Try with manifold inputs. How can i fix this problem ?

 

Sorry for my bad english. 

 

Thank you for your time.

 Appreciations.

Your English is excellent.

Your ability to fully constrain sketches is not so great.

Loft4 is the problem. Pull the end of part marker up over Mirror2 and look at the flat face of your first loft. There is a void there between loft3 and loft 4.

While I take a look at your geometry - you might take a look at this document http://home.pct.edu/~jmather/skillsusa%20university.pdf

 

I noticed that your First sketch isn't constrained and it looks like you might be doing too much work to get the geometry.

 

 

Maybe something like this is what you are after (see attached)

Thank you for such short notice, but there is still one question that remains. Why sweep tool connects to solids when loft tool isn't able to do it ?

 

Thank you for your answer.

Appreciate your help.

Loft  is able to do it - if you set up the problem correctly.  But it looked to me like Sweep would be less work.  Why do more work?
If the sweep doesn't give you desired geometry, we can keep working on a more complex Loft solution.

Took another look - Loft IS easier (see attached).

Attach your ipt file here.

 If the file size is too large - find the red End of Part marker in the browser.
Drag the red EOP marker to the top of the browser hiding all features.

Save the file with the EOP in a rolled up state.

In Windows Explorer right click on the file name and select Send to Compressed (zipped) Folder.
Attach the resulting *.zip file here.

I'm having the same problem trying to shell this part. I've redone the loft based on previous comments but hasn't madea  difference. Any help would be greatly appreciated! Thanks.

Always try to include a screen shot for those with different versions and perhaps we can help with solution. Years of one-of-a-kind parts (dams, bridges and tunnels) with loft and sweep.

You can see what was different by examining the Feature browser.

Drag the red End of Part marker above The Shell feature.

Shell "thickens" ALL the faces of the part except those you select to remove.

 

The bottom of the part didn't need to be shelled - so first the part was Split into two different Solid Bodies.


Drag the EOP below Shell.

So then the Shell was done only to the upper solid body.

 

Drag the EOP below Combine.

Now the two solid bodies are combined back into one solid body.

 

There is a better way to model this.

Do the features that need to be shelled first and then do the features that don't need to be shelled.

 

BTW - there are now three different problems in this one thread.

It is better practice to start a new thread for a new problem and only supply url reference to thread you found through search (if it has relevant information).

Here is a slightly different technique - be careful - I changed at least one dimension, and if you intend to make this into separate sheet metal parts there additional considerations.
