@Officer SEAN, glad you were able to get it working! And the hotbar trick is a great trick. Works with buttons on button pannels too lol. And thank you for the compliment. Glad you're enjoying it.:)

yay! I got it working! in creative I just used a projector (I didnt know about the trick with putting the projector in hotbar it makes it really easy to adjust horizonal, verticle pitch and all that! Seen someone did that on a youtube video) and the ventaltion system you use is pretty cool too! :)

yeah I'll get it working one of these days lol, I knew about the cut/paste I even tried projector but Ive really never used projector before and it seemed very tedious.

@Officer SEAN, Lol Its all good. If you didn't know, looking at an object and holding ctrl x cuts the object from the world and ctrl v pastes it into the world. Since its the modular parts are all a blueprint it acts differently when you try to pase it into the world than say placing a block. Often I've found I have to copy it into the world then cut and past to actually apply it to a nother object. Its kind of strange. You'll get the hang of it though. Feel free to ask questions any time :)

Ok thanks, I tried using the creative and survival methods... I'll try the cut/paste method, unfamiliar with programming block (I'm still pretty new to SE LOL) :)

Yes they are. If you're trying to copy and paste using admin or creative mode I've found sometimes you have to pass it then cut it while looking at the edge you want to have line up. In survival mode using the programmable block you can definitely line them up.

Are these truely meant to snap together? Awesome idea but I'm pulling my hair out here trying to get any of these to snap together or even line up in the slightest
