Making an angled wall

Dear all,


after KimT his post I read the document he refered to and wanted to add something I made myself.
I invented this technique independently, although someone might have had a similar idea before.
I wrote a small computer program to calculate how you can build angled walls without stressing the bricks.
So, basically, when pythagoras gives an integer output for two integer inputs.
A small usefull set without doubles is this set:

since this are heart to heart distances, a one should be added to the numbers to count the studs involved.
So the modified list will be:

How does it work!:

Example1:
the first row is
4 -> gives size of plain
5 ->gives size of plain
6 -> gives length of beam

this means that two studs on the far corners of a 4 by 5 stud plain:

can be covered by a 6 stud beam:

Example2:
6
13
14
studs on the far corners of a 6 by 13 stud plain:
Posted Image
can be covered by a 14 stud beam:

Example3:
The fourth row will gove
9
16
18
studs on the far corners of a 9 by 16 stud plain:
Posted Image
can be covered by a 18 stud beam:

Ofcourse, the set can be expanded upon taking jumperbriks into account.
This will reduce the length of the beam by almost a factor of two.
The basic set can be used only we will calculate using half distances inseatd uf full.
This will mean the original set is devided by two and than one is added to all numbers since we consider the
heart to heart distance.
Exmaple of recalculating row one:
3
4
5
will translate to:
3/2+1=2.5
4/2+1=3.0
5/2+1=3.5
So we need to attach a jumper brick to the beam as well.

Thanks Teddy.
You're the man.
I'll have to find me a load of bricks and start learning to use this SNIR (Studs Not In A Row) technique.
Thanks for this very good tutorial.
I'll add it to the Adv. Building Tech topic :thumbup:

Dear KimT,

thanks for adding it to the Adv. Building Tech topic! :classic:
Hopefully, my tutorial will be of use to someones MOC.
If anyone wishes to comment on or ask a question about this particulair technique, please post in this topic so I can
keap track of them and possibly give you an answer.   :tongue:

Kind regards,

Teddy

I've been doing this for ages and am sure wasn't the first either. It is an example of what I know as SNARL: Studs Not At Right Angles.

Lowlug have a number of techniques in their online techniques library, including the one based on pythagorean triplets:

(with contributions by fellow Brickish members Jason Railton and Mark Palmer)

I don't use it for walls but use it to mount wings:

BTW, the pylons under the wings use the variant of 3-4-5 using a jumper plate to get 1.5-2-2.5 such that they are aligned with the fuselage.

Ralph

Thank Teddy, this really comes in handsome !

Not for my classic medieval castle, but for the piratecastle I am building to go with my newest ship MOC.

It is a very useful technique and it's always good to show it again to people who otherwise would never have thought about it themselves.

EDIT CGH: please do not quote entire posts containing a lot of pictures, thank you!



A really great tutorial there Teddy, I read something similar in a mindstorms book. It really is a great read.

Verah nice little table!

And ralph, that's got some great pictures (and great use of the Pythagorean theorem!), but it's in german.

I love SNIR and SNARL!

Dear Dr. X,

the tutorial of Ralphs link isn't in German, it is in Dutch.  :tongue:
Kind regards,
