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)|
First of all, I do apologise for my late reply.
An assembly volume is a SET of physical volumes:
<assembly name='MyAssembly'> <physvol> <volumeref ... /> <rotation ... /> <position ... /> </physvol> <physvol> <volumeref ... /> <rotation ... /> <position ... /> </physvol> </assembly>
In GDML, an assembly volume can be referenced by its name - just like a logical volume:
<volume name='MyVolume'> <physvol> <volumeref ref="MyAssembly"/> <rotation ... /> <position ... /> </physvol> <physvol> <volumeref ... /> <rotation ... /> <position ... /> </physvol> </volume>
Now all the volumes collected in the assembly volume 'MyAssembly' are placed into the logical volume 'MyVolume'. Now 'MyVolume' has three children: one placed directly and two additional coming from the assembly volume 'MyAssembly'.
Please let me know if you have any further questions!
P.S.: Next week I will be away
