I figured it out myself with trail and error but there was a tutorial already D:
You learn allot better through trial and error anyways. This is one of those things you can't get a good grasp of without trying everything first.
If someone did make an excruciatingly complex tutorial with pretty pictures and fancy lining all the people complaining for a tutorial would still do absolutely nothing.
Edit:
You could have that brick, a brick with a stud on the bottom that is rounded and attached to the top (like the 1x1F Print Brick) and then another that attaches to the bottom. Then you can have piping that goes along a ceiling or on a floor - attaches right with studs/Blockland logic and appears rounded.
I thought of this too, I've never gotten around to trying it though.
