Shell feature?

[banishmemory]

Does anyone knows how to create shell feature?
For instance - solid box from a cube. As far as I see the command is missing.
It is like removing a side of the cube and adding a thickness to the resulted surface body, but it is not exactly.
Actually I'm not sure if it is possible also an adding of a thickness to a sheet body.

So... Help.. Please... Anyone?

Thanks!

This will give you a hollow box without a top:

Code: Select all

cube = Part.makeBox(cubesize,cubesize,cubesize)
faceList = cube.Faces
myShell = Part.makeShell(faceList[0:5])
Part.show(myShell)

This shouldn't have been posted in open discussion. This is clearly a help request, not a post to discuss about FreeCAD's future, so I'm moving the topic to the Help forum.

There's actually a GUI tool for us non-programmers. It's the Part Thickness tool. I know, the name is not very self-explanatory. But shell is a term already used in FreeCAD to define a set of faces that make an enclosed volume.

Select the face(s) you want to open, then click on the Thickness tool. In the task panel, you will have to set parameters, such as the wall thickness. A positive value will create walls outside of your initial shape. To keep the same outer dimensions, input a negative value.
