Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.
Inline: Display the subject line only or also the text of the posting(s); for the choice "All" the "Outline" choices are switched off.
|1||0||1||no text / full text of posting|
|2||1||All||text for level 1 only / text for All postings|
Outline: Choose the depth of the posting thread, successive toggle controls provide increasing detail.
|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|
Hi Kazuyoshi, I was actually wrong in my previous reply, I apologize for it. You can actually use mathematical expressions, and therefore also trigonometric functions, in GDML. This functionality comes for free from the fact that the GDML reader inherently adopts the CLHEP expression evaluator. Therefore, as Radovan pointed out, you can define expressions with mathematical functions, provided that the final arguments are literals (in case of combined/nested expressions you should split them, assigning to variables as constants). Cheers, Gabriele
