I'm working on a model as I'm learning Blender for educational purposes. I have a collection of objects that together make up the "pillar" collection. I'm going to duplicate this collection multiple times (in the below screenshot I did it once already, for testing purposes).  However, I will continue to manipulate all objects within this base collection going forward, and I want all manipulations to propagate to all the duplicate collections.  I've read about – and played around with – linking and child-parent relationships, but I have yet to find a solution that allows me to pick one whole collection as the base model, and then see any changes made to that collection applied to all other relevant collections.  Is this possible? If it is, can I do it within a single .blend file, or does it require me linking another blend file into this one?
Apart from testing it myself, I've seen a few posts  and , including from Sketchup users like me, sort of circle around this topic but never ask this question directly. How can I overcome these problems in DupliGroups or Collection Instances?  moving its origin seems to require moving to World origin (and using up a layer for clarity) &lt;=&gt; linked meshes have their own local origin which I can move data around in Edit Mode (easy enough)  It is impractical to link up DupliGroup data to previously created meshes because the origin mismatch as above, and the mesh data that remains in it and needs to be deleted somehow  Linked meshes don't have the above two problems (can be 'blocked in' and then detailed up all at once) but I can't add objects to them, only faces. Say I'd like to add handles as linked meshes, because handles are used elsewhere in the model too.    How feasible would it be to make a linked object type with deeper hierarchy? Say an object that would look at its children and simply make every other instance have the same children. It would also mean dragging and dropping in outliner would be the simplest way to manage it by the looks of it.

Prove $\alpha \in R[[x]]$ is a unit iff $a_0 \in R$ is a unit biblatex: change name of author according to language? Usually a name stays the same in whatever language. So, whenever I quote a work by Knuth -- be it in an English article or a German one -- I will quote him as Donald E. Knuth.  This is not always the case with ancient or medieval names. They are spelled differently in different languages. Two examples in English | German | French:   Aristotle | Aristoteles | Aristote Thomas Aquinas | Thomas von Aquin | Thomas d'Aquin   This means that when I write an English article, I need a bib-file that contains the English names, but when I want to write a German article, I need to go through my bib file and change the names accordingly. Depending on how often I in fact publish in English or German this could keep me busy and is prone to error.  So, I though, maybe I could have the different names already included in one single bib-file and let biblatex choose the correct name according to the primary language used in the document. Any ideas?  NB: I do not want to use in one single document both spellings Aristotle and Aristoteles (as the following MWE might make you think). Of course, if the article's primary language is English, then all the references to Aristotle will use the English spelling of his name. However, I want to be able to write articles in different languages, without (a) having to edit my bib-files each time or (b) generally maintaing not one single bib-file but two different ones, one for each language, or (c) having two distinct entries in one bib-file  MWE  % !TEX TS-program = lualatexmk \documentclass{scrartcl}  \usepackage{fontspec}         \setmainfont[Ligatures=TeX]{Times New Roman}  \usepackage[ngerman, british]{babel} \usepackage[babel]{csquotes} \usepackage[style=verbose,abbreviate=false,backend=biber]{biblatex}  \usepackage{filecontents}  \begin{filecontents}{\jobname.bib} @book{aristotle:ross:1924,     Author = {Aristotle},    % It is here, I think, that something could be done, e.g., ...

I want to take some chocolates to offer in my luggage. Chocolates are a bit sensitive to heat, though. What is the average temperature inside a cargo hold? 'Average by' itself can be misleading. What is the max temperature there?  I don't know much about airplane mechanics but I assume they have some cooling systems like any other engine. Such systems, depending on where they are placed, might influence temperature in the cargo hold. I also fear temperatures in the ground while exterior temperatures are higher, and luggage is being put inside. What are max temperatures near the airplane in such situation?
