System Information
Operating system: Windows-10-10.0.22631-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 850M/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 546.29

Blender Version
Broken: version: 4.0.2, branch: blender-v4.0-release, commit date: 2023-12-05 07:41, hash: 9be62e85b727
Worked: (This is an old bug I don't know)

Short description of error
When you add a Object by Shift + A, its default size depends on the 3D View Grid scale or the Unit Scale.
However, if you add an object before changing the Grid scale (or Unit Scale), the new objects will maintain the size of the object you added first.

Exact steps for others to reproduce the error

  • Change grid scale in viewport overlay to 0.1 (or the unit scale to 10.0 if you prefer to work with unit scale).
  • Create a cube by shift + A (It correctly respects the grid scale)
  • Change the grid scale in viewport overlay (or the unit scale if you are working with unit scale) back to 1.0.
  • Create another cube by shift + A

You will see it's same size as first added cube. It does not respect the grid scale anymore.

I think blender should consider grid scale all the time when creating default objects not just for the first item and should not lock it until reopening your file.
Thank you.

This is not a bug but can be improved. When you add cube for second time, "size" property is already being initialized hence the new size won't be set here: https://projects.blender.org/blender/blender/src/branch/main/source/blender/windowmanager/intern/wm_operators.cc#L1020-L1023
So even when grid_scale is 1.0, size will be size = default_scale_value * 0.1 (grid_scale_old) * unit_scale_factor

Yes this is old one but reported resentyl... grid scale has nothing to do with it but it should be parent of primitive sizes... will check this to be fixed thanks.

Hi. how its going with this issue? maybe parenting this to wievport will be better insted of mesurments or blender scale? always when I add something new if it is something big or something small I usualy set my view first to look at then add new object. Regards.
