Delete face does not work correctly in multisolidbody modeling

[pasi.annila]

Created a model with 2 solid bodies...

The 2nd solid should be reservour so I just deleted top face with delete face command (and thicken it).

The result is unexpected and not good one!

In case I have made (derived) a component (solid9_1.ipt) the geometry is "lost" and part deriving needs to modified.

Can you share it ...

hard to see everything from the images. 

Shell wouldn't have worked?

[alex.haerens]

Delete face is a command with a will of its own ... Sometimes you have no other choice but when there is another option : use it !

In your case you can do the trick in one command : feature "shell" with the correct wall thickness and use the option "remove faces" to select that the top should stay open.

Shell features are used far too little. Drawing a block, adding a shell feature, where you choose an individual wall thickness on one side and click on 4 faces can produce you an L-profile with unequal wall thickness. And all this from a 1-click rectangle sketch with 2 dimensions.

Your image shows exactly what I would expect to happen.  Solid9 has had a face removed, changing it to a surface body (surface body count goes from 153 to 154).  Please attach the file, or at least show another screen shot with the End Of Part all the way at the bottom, below the Thicken feature.  That should change the surface body back to a solid.  But it won't be the same solid, so I wouldn't expect the derive links to be maintained.

As @alex.haerens suggested, Delete Face and Thicken is not the right method for this job.

Hi Pasi,

You don't need to use Derive to get the second body. Simply edit Thicken and change type from Join to New Solid. You will get the second solid back. Is it what you are looking for?

Many thanks!
