Earns its place in the blender_extensions library as a compact add-on focused on one job: grid alignment, with name-based grouping for scenes that follow consistent naming conventions.
Aligning Horizontally Mini is a Blender add-on for arranging selected objects into a customizable grid inside the 3D viewport. You set how many objects sit on the X and Y axes, then adjust spacing separately on the X, Y, and Z axes to control the layout.
Beyond a single grid, the add-on can group objects by name. It splits each object name at a chosen character, with a period as the default, so objects sharing the same prefix land in the same group. A group placement direction setting positions each group along X+, X-, Y+, Y-, Z+, or Z-, and the active object can be sorted to the front of the arrangement.
The tool runs from Object > Transform > Align Objects in Grid, with its settings exposed in the operator panel. An option to pass active objects removes them from groups when needed. It is compatible with Blender 4.2 LTS and newer and released under the GNU General Public License v3.0 or later.
Aligning Horizontally Mini is best for arranging multiple selected objects into organized grid layouts in Blender's 3D viewport, especially scenes built on consistent object naming.
Aligning Horizontally Mini is completely free to download and use.
Aligning Horizontally Mini is compatible with Blender 4.2 LTS and newer, so any version from that release onward can run it. The add-on requires no special permissions to install and is released under the GNU General Public License v3.0 or later. If you are running an older build of Blender, you would need to update to at least 4.2 LTS before the add-on will work. For the current compatibility details, check the developer's page linked with this entry.
Aligning Horizontally Mini runs from the menu at Object > Transform > Align Objects in Grid. First select the objects you want to arrange in the 3D viewport, then open that menu entry. The operator panel exposes all the settings, including axis counts, spacing on each axis, grouping options, and group placement direction. Adjust those to your liking and click Execute to align the objects. If objects do not align as expected, confirm they are all selected before running the operator.
Aligning Horizontally Mini groups objects by name when Group by Name is enabled. It splits each object's name at a chosen split character, which defaults to a period, and objects sharing the part of the name before that character land in the same group. For example, Group1.Object1 and Group1.Object2 would belong to the same group. The Group Placement Direction setting then positions each group along X+, X-, Y+, Y-, Z+, or Z-. If grouping is not working, verify your object names and split character are set correctly.
Aligning Horizontally Mini is listed as free in this catalog, and it is distributed under the GNU General Public License v3.0 or later. The extension states it requires no special permissions to install. For the most current licensing terms, download options, and source code, refer to the developer's page on GitHub. Since terms can change over time, checking the official listing is the safest way to confirm how the add-on is licensed before you add it to your Blender setup.
