Thanks for the response Soroban, Fancy ASCII illustration too btw haha.

The problem i am having though is when I do repeat the process.

Lets say I cut off R,S,B,P to get:

Code:

: - - - - - φ - - - - - :
D C Q
- *-------------*---------*
: | | |
: | | |
1 | | t |
: | R *---------* S
: | | | |
- *-------------*---------*
A B u P

Now I have R,T,B,U .. The problem i'm getting usually happens while squaring off this section on either this step or on the following step ( R,T,"V,W"? ) ...somehow I keep finding myself left with more space then what I should have.

I assume, obviously, that my measurements have to be off in order for this to happen. What I don't get is how they could be off in the first place unless the "negative space" ,i'll call it, is the summation of some earlier lines being short a millimeter or two.

I'll try to illustrate what i'm being left with -

Code:

^ ^
^ ^
C* *Q
| |
R T |
*---------*-------------------*S
| | |
X*----------*Y |
| | |
| | |
V*----------*W |
| | |
| | |
<<*------------ *---------*-------------------*
A B U P

Alright, So this illustration shows the rectangle zoomed in to the R,T,B,U sector.

now, lets say I had just created the cut from T-U and I shifted my attention to R,T,B,U...the next line I need to create is V,W, so I take the length of B,U and bring it over to B,R to get B,V and I create my square V,W,B,U.... Now, notice R,T,V,W... it's an usual shape.

-The cut for V,W should actually be where I placed X,Y... giving me the horizontal rectangle R,T,X,Y which actually looks a lot closer to the dimensions of a golden rectangle even in this illustration.

However, I keep getting that V,W line...which I should call "checkmate" lol because I can't follow it up with another cut. When I do I end up creating an adjacent square to V,W,B,U and of the same dimension, leaving me with the "negative space" I was explaining earlier, similar to the shape of R,T,X,Y...

...it's definitely not an infinite spiral i'm drawing lol. If anything B,U,V,W and X,Y,V,W should both = 1 leaving me with nothing correct?

So whats potentially causing this problem?

my lines are accurate to 1/16 of an inch.
