In other drawing programs, I can draw separate things and then “Group” them so they behave as one. In particular, moving, rotating, and scaling automatically applies to everything rigidly.

The “Collections” in Blender 2.8 doesn’t do this.

Assigning parts to other parts as “Parent” causes it to re-interpret the position and scale relative to the new parent, rather than just making it follow the parent from now on.

    $\begingroup$ "“Collections” in Blender 2.8 doesn’t do this" it does. Same as in 2.79- you needed to create an instance of the group to make objects in it actually behave as one in 2.8 you have to instantiate collection. $\endgroup$ – Mr Zak Mar 18 at 16:11

Parent

enter image description here

You can select many objects first, choose the candidate parent last and then parent.

Please note Blender always has many options to achieve similar goals. There is the concept of Join and Blender Armature. This proposed answer will focus on Parent.

Parent menu has many options Control-P. Use the keystroke because Blender will give you more options this way

enter image description here

To remove the Parent with options press Alt-P

Those options may keep your original transformation. I believe the parent feature is able to do what you want. Object Keep Transform.

Parent and Group are two distinct concepts in Blender. So you may want to use Blender terminology.

Here is a video tutorial for creating a group and parenting. It may or may not be the same version of Blender you are using. You may choose a different tutorial on the topic of [Parent] which you like better. I just did a quick search.

    $\begingroup$ Parent did not work; at least, not for grouping after the fact. When I assigned 'part' the parent of 'main body', it jumped to a new position and size; I assume it was re-interpreting the exiting numbers relative to the parent. When I "group" something, it should remain unchanged! Just, stay together for subsequent operations. $\endgroup$ – JDługosz Mar 18 at 15:04

  • $\begingroup$ Again please do not casually use the word group in Blender. It will be confusing at points . $\endgroup$ – atomicbezierslinger Mar 18 at 15:09
  • $\begingroup$ The "Group" feature you refer to appears to not be applicable to Version 2.8. I think turning off “Keep Transform” is what I was looking for — It's not in the Object menu, but the ctrl-P menu showed the same as yours. Thanks! $\endgroup$ – JDługosz Mar 18 at 15:10

Same problem: How to group objects in blender so they behave like am used to in coreldraw(the usuals scaling,translation and ...)? turned out parenting was the apparent solution after jumping on a googling adventure. So I decided parenting wasn't the solution well because I wanted to, sadly it meant I always needed to select one object before all others start misbehaving according to my wishes(scaling,transla...).

MISSION ACCOMPLISHED: After grouping a set of objects with Ctrl +G I selected one object in the group and then Shift + G -> Group -> my_group_name to select all the other objects in the group and you wouldn't believe it, I discovered my purpose. I finally realised my destiny was to group objects in blender, the universe always finds a way to put things in place at the right moment.

last night I sardined 1,000 sceptres(mesh) and you wouldn't believe it they grouped like magic. today I hope to make 3000 if nobody stops me... The sky is the limit

Just in case anyone else comes looking for the same thing.

  1. Create an empty.
  2. Size the empty to encase your objects.
  3. Parent all objects to the group.
  4. In the outliner make all objects except for the empty non selectable.

Items now act as what most people would consider a group. (for the most part)

EDIT

Found this addon does what you want.
