Blocks Vs Groups, When and Why use either ?

As in many other cases, the robust AutoCAD sometimes offer too many options, multiple possibilities that all seem to help the USER get a similar result – but the question is what are the best practices?

Regarding Blocks, I guess it’s too late after 35 Years of the Block – as we know it – to filter out objects at the event of the block creation. If it was possible, I would ask to filter out annotations (Texts, Mtexts and Dimensions) while selecting the objects…I even would consider changing the Prompts at the command events…

Regarding Groups, I would consider the option of native import/export of groups to use across files…

Blocks Vs Groups – First thing First

Blocks:

These are Named Collections of AutoCAD Objects. In the Block Definition Framework, You can find the Insertion Point, The Units, some Block Behavior Options, the Annotative Option and The Static or Dynamic Options.
The Big Issue is all about the purpose or the function of the Block. Is it a Library Item (such as a Chair, a Piano or a Bolt) or a Symbol (such as a Section Mark, a Grid Bubble or a Scale-bar)? And then again, why can’t it be an apartment that can be used as a mirrored block containing all the selection altogether to really take advantage of the software program? Try it (if You Haven’t Tried it Yet) and discover the facts of life: The Mirrtext=0 won’t help and all the annotations and dimensions will keep unintentionally mirrored. Blocks’ Insertion Best Practices: The Tool Palette will dictate the Block its Layer…

Blocks Vs Groups
Blocks Vs Groups – The Power of Groups…

Groups:

Those are Object Selections too. The differences are that to create a group is easier and more straightforward: Just make a selection, Right-Click and opt for Group (within the POP 0 Group option). From now on you can keep selecting the objects one-by-one or as a group – This is connected to the pickstyle settings or the Group Selection On/Off. Groups are marked by a bounding box and have a grip at the Geometric Center of it. Groups don’t oppose to any Geometric Manipulations Whatsoever, they respect the Mirrtext=0 and cause no problems. By Changing the Pickstyle, you can keep editing the contents of the group as much as You like. If a single object needs to be moved or even erased click the Selection Off, do your thing and while getting the Selection On, the group will behave itself as expected. Unlike Blocks, groups cannot be brought into a Tool Palette…

Blocks Vs Groups

Blocks are saved within the File and so are Groups. The can both be named by the user having a properly explicit name. In both cases you can drag through Tiled Vertically open files. In the Case of the Block, If there is no block using the same name, it will come as is into the target file, otherwise, it will come from the Target file’s Memory. When dragging a Group from Source to Target, In the Target file, the Group will be lost and will need to be recreated – But this is very easy to achieve.

There were some versions the group seemed to be absent from, but this was only in terms of interface. The Functionality is from release 13 (something like 16 AutoCAD Versions old). Then it returned and hope You’re Using it since there are not really any alternatives…
