Select By Index earns its place in the Blender extensions library as a small, single-purpose Edit Mode utility. At 3.1 KB and written in Python, it handles range-based selection of mesh elements by index, and added a Count input mode as of version 1.3.0.
Select By Index is a Blender add-on from Eric-Banker for selecting all vertices, edges, or faces within an index range. It works in Edit Mode, accessed through the Select menu under "By Index."
Inside the tool you set the selection mode—vertex, edge, or face—and define the selection range using either a start and stop index or a selection count. A selection behavior option lets you replace the current selection or add to a prior one.
Version 1.3.0 added the "Count" selection range input mode, revised the GUI for better display and handling of the range input modes, and brought a minor performance improvement for very large meshes. The add-on is written entirely in Python, requires no special permissions, is compatible with Blender 4.2 LTS and newer, and is released under the GNU General Public License v3.0 or later.
Select By Index is best for blender users who need to select mesh vertices, edges, or faces by index range in Edit Mode.
Select By Index is completely free to download and use.
Select By Index lists compatibility with Blender 4.2 LTS and newer, so it runs on the 4.2 LTS release and later versions. The add-on is written entirely in Python and requires no special permissions. You can add it by dragging the downloaded package into Blender or installing it from disk through Blender's extensions preferences. Once enabled, it appears in Edit Mode under the Select menu as "By Index."
Select By Index is used from Edit Mode: open the Select menu and click "By Index." From there you choose the selection mode—vertex, edge, or face—and define the selection range, either by entering a start and stop index or by using a selection count. You can also set the selection behavior to replace the current selection or add to a prior one. Version 1.3.0 revised the GUI to improve how the selection range input modes are displayed and handled.
Select By Index is released under the GNU General Public License v3.0 or later. The add-on requires no special permissions in Blender and is listed here as free. It's a compact download at 3.1 KB and written entirely in Python. For the current license text and source code, see the developer's page on GitHub. Version 1.3.0 is the latest release, published in March 2025.
Select By Index 1.3.0 added a "Count" selection range input mode, giving another way to define how many elements to select alongside the existing start and stop index inputs. This version also modified the GUI for better display and handling of the selection range input modes, and included a minor performance improvement for very large meshes. It was published in March 2025 and is compatible with Blender 4.2 LTS and newer.
