Shell problem
Shell problem
(OP)
Hi,
I attach a Parasolid part.
I can't shell.
I would like to shell as the image of 2 mm.
Exist a tool or something to understand where the shell fails ?
Thank you..

RE: Shell problem
It looks like what you wanted to be subtracted out was not subtracted out. I did a "join Face" and all the faces went together and became a simple block.
You should be able to do the shell after you figure out what went wrong with the subtraction.

RE: Shell problem
There is a procedure in PS where you 'imprint' a set of edges on the face of a solid. This occures often in PS and is the equivalent of a 'Divide Face' operation in NX, but in PS it's most often just one of severals steps taken in order to produce a new model, such as when performing a 'Shell' operation or even a Boolean.
For a Boolean subtract, PS will first compute all the face-face intersections, then perform an 'imprint' on the faces of the model using these intersection curves, then it will identify and delete the unneeded faces and then 'glues' the rest of them together, after which it will label the results a 'solid' if it forms a 'water-tight' body or a 'sheet' if it does not.

However I suspect that you may have wanted something else which I will attach in a separate post.

what you have done it's not what I would obtain.
Please see my attached image.

RE: Shell problem
your second solution permit me to shell the part, but as the image that I attach...two face aren't perpendicular.
I tried after your solution divide the face and add draft or use the ST command, but I can't do it.
For the dx face it's possible with divide face, but the left I can't.
Have you some suggestions ?
Thank you...

RE: Shell problem
the result it's correct.
Te only question is :
Add thickness to faces or shell, why don't produce the same result ?
I think that the thickness command make offset face, trim together and produce a closed volume.
The shell command make offset face, trim together produce a closed volume and subtract with a boolean command to the original body.
It appear identical, but as we can see the result it's different.
Have you some comment ?
Thank you...
