Hi Lang!


I don't know if this was mentioned above...

Objects disappearing is often an unsatisfactory result of the Boolean commands.

I'm not sure why, but I do know how to quickly work around this problem:


Let's take your bottle Network and your horn shapes.

1) First take the network object and activate the Boolean-Merge command.
2) You should be left with the horn shapes with the network gone. You should actually have the intersection of the horns and the network, plus the remainder of the horns. The network will be gone. - COPY the good stuff.
3) UNDO and select the network again.
4) Run the Boolean-Difference command by selecting the network shape first.
5) You should now have your network bottle shape with holes in it. - PASTE!
6) Now drill-select those outer surfaces and delete them.
7) Join the objects you really wanted into one surface.

Enjoy. :-)
