How to get correct dashed line of this picture? 12

7 As a dirty hack, you could draw the circle two times: once with a solid line and after covering this up, a dashed line on top:

7 This saves and reuses paths either inside or outside the triangle. In order to accomplish the latter, an inverted clip is utilized, which borrowed from [stackexchange](https://tex.stackexchange.com/a/59168).

8 This answer comes in three parts, sorted by increasing complexity. The IMHO "best" solution is at the end. Let us start with a very simpleminded proposal, which only works in the limit of small phi, i.e. the second argument of `\tdplotsetmaincoords{<theta>}{<phi>}` needs to be such that the absolute value of its sine is small. Next, a function `R` is introduced that specifies the radius of the volume as a function of `x`. Then the planes and volume are drawn step by step.

5 Another approach could be to test the documentclass during the package loading (caveat: this won't deal with edge cases described in [this comment](https://topanswers.xyz/transcript?room=1259&id=62326#c62326)):

5 Instead of using `\@ifclassloaded` in the key's code, you could test `\AtBeginDocument` which class is used and define the key accordingly:

5 Here is my take at this; I hope this helps a little bit. I renamed `\change` to `\changeBaseline`. It works both in the preamble and in the `document` environment.

Problem with \doublespacing and cases 21

9 You can accomplish this by setting `\baselinestretch` back to `1` inside the definition of the `cases` environment. This is a multiplier for the distance between lines in a paragraph (and also between the rows of the `cases` environment) and it was set to `1.667` by `\doublespacing`.

5 The font is working fine with LaTeX, the problem is rather that the `Bitstream Vera Sans` font you chose, does not contain the rupee symbol. You can see this by inspecting the content of the `.ttf` file:

11 The following defines a `circ path` for the `to` syntax. There is most likely a better way to define it, but my Ti*k*Z skills are limited.

CarLaTeX
6 This is very much based on [Skillmon's nice answer](https://topanswers.xyz/tex?q=680#a755), but has some modifications. Most importantly, if the fraction is very small or very large, i.e. when the circle is very close to either start or end point, there will be no spurious extra lines. The syntax is also a bit shorter. At the technical level, this variation uses the partway modificator (see section **13.5.3 The Syntax of Partway Modifiers** of pgfmanual v3.1.5) to position the circle.
