comment Drawing knots with tikz - no visible crossings
@ulead86 See updated answer. That gave me the clue to what was actually going on here. Thanks.

comment Drawing knots with tikz - no visible crossings
@ulead86 The difference between the two diagrams comes in the scale=X option on the outer tikzpicture. The issue in your diagram is that the crossing is being ignored because it is failing a distance test. By scaling up the diagram, you effectively lower the tolerance on that distance test and so make it more likely that the crossing will get seen.

comment “Z-level” in TikZ
@Kpym It's been over two years since I last looked at this code so I don't actually remember what that was for. Most likely, it was part of some code in an older version that I forgot to delete in the last version.

@cfr Interestingly, the necessity of no spaces is because the knot environment is defined using \NewDocumentEnvironment from xparse rather than the standard \newenvironment.

@cfr Did you remove the space? If you don't delete the space between \begin{knot} and the [...] then the part in [...] isn't taken as the optional argument to the knot environment but is passed on to \tikzset which doesn't have the same effect.

comment Adding a large brace next to a body of text
@cfr Having actually just read the answer again, I realise you might be referring to the infamous tikzmark library rather than a library to put braces next to text (as I originally thought). Are you?

@cfr Is there? What library is that? (Please provide a link rather than a hint!)

comment Setting \tikzstyle inside \foreach
The code in a \foreach loop is executed inside a group and so outside it the styles are not set.

comment How do I display pi in LaTeX like Don?
Seeing this, I find myself wanting to ask the question "How do I display phi in LaTeX like Fibonacci?". I'd like to see a golden spiral with the digits of phi scaled so that when it reaches the second square then it is exactly 1/phi the size it was when it set out.

Because, because, because .... because of the wonderful things TikZ does! (PS Thanks for the edit on my recent post.)

As the answer says, it's part of the TeX-SX launchpad project. This can be found at <bazaar.launchpad.net/~tex-sx/tex-sx/development/files>;

@anderfo Don't know if it's still useful, but I hacked something together.

comment How to declare variable sizes in tikz to let LaTeX decide how to fill the page
@JosephWright These days I unfortunately do not have as much time for TeX-SX as I used to. Any comments of mine that should be converted to answers are fair game for others to do so.

comment Tikz, Tangent Line to a Circle
(I think we've seen this before, but for a rectangle node shape. The solutions for that ought to be applicable here, but my search skills are sadly lacking.)

comment Tikz, Tangent Line to a Circle
It's all to do with line width. The position D.north is on the very outside of the circle, so the middle of your incident line is aligned with the outside of the circle line. There are a couple of ways to solve this depending on how technical you are prepared to be.

comment Fancy Table of Contents
(Our general policy has been to not down-vote beyond -1. Once it's at -1 then it's clear that there's something wrong with the question and it needs improving. If it doesn't get improved, it will be closed. Beyond -1 is therefore unnecessary. So @ChristianHupfer is right to find that. There's a meta question on this which I can't find right now.)
