Free script(s) in .ZIP file and demo moi file,
created with Michaels help to create "box sections" with total ease and speed...

Simply create a solid or "box". select the object(s)...run BOXSHELL
script selects the small edge faces, then goes to shell which acts as pass-through
as it selects two faces per box.

The other scripts are named for fast recall using command box typing (or shortcuts)
and these ones bypass the shell dialogue and set the distance or box section wall thickness as
like this, type "BOX10" for box section to be 1mm wall thickness...

1.0
1.2
1.5
1.6
3.2
(mm)

>> you can edit the last line in the .js script to create any box section wall thickness you want e.g.
moi.command.execCommand( 'shell soliddistanceinput=3.2 done' );

or

use boxshell to use the shell dialogue each time..
