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)|

Dear Rajani, I will try to provide some information in response to your questions. As I have not understood parts of your posting, I am making some assumptions (see below) and also asking for more information. rajani wrote: > *** Discussion title: Geometry > Email replies to PublicHyperNews@slac.stanford.edu must include: > In-Reply-To: <"/geometry/630"@geant4-hn.slac.stanford.edu> > Subject: ...change this to be about your reply. > > Hi all!!

Did you create this, - by subtracting one volume from another - by making a union of boxes, each one a 'plate' of small thickness.

Could anyone please tell me the way to do it. A replica slices its parent volume into different pieces. So to create copies of an unusually shaped volume, you cannot use a G4Replica. Simply creating several physical volumes from your logical volume, each displaced is a good solution. > 2) Next, problem is i want to give curvature to my this replicated > geometry.

Could you please try to explain whether you are putting together (union) different boxes, or creating your solid in another way. If you have a graphics program that can create a gif, jpg or other simple picture, it would be good to post a link to this too. > Hope i could make my problem understand. Thanking all Rajani I hope that my first suggestions will help. If you can provide further information, we can try to provide further suggestions. Please also let us know your affiliation and the nature of the project that you are working on. Best regards John Apostolakis
