Mesh Align Plus stands out in the blender_extensions library for pairing an Easy Mode for quick face-to-face alignments with an Expert Mode that opens up complex ways to define keys and targets. It's compatible with Blender 4.2 LTS and newer and requires no special permissions.
Mesh Align Plus lets you pick features in your Blender scene — lines or flat surfaces known as Alignment Keys — and align objects to them. To align two flat surfaces, you select the first surface, then the second, then choose what to apply the alignment to, and the first surface moves to meet the second. The features can come from any object, and you can move a single object, several selected objects, or a mesh fragment while modeling, all following the same steps.
Beyond alignment, the add-on captures measurements from your scene for custom transformations: find a line/plane intersection point, grab face normals, and measure angles between lines, where a line can be an edge or two verts. A panel with two alignment key slots runs calculations based on what you load into them, such as angles, line/plane intersection points, and line normals. Some calculations, like line length, work only on the item in the first slot.
Easy Mode covers simple alignments like matching faces from different objects, while Expert Mode adds options for defining keys and targets in more complex ways.
Mesh Align Plus is best for blender modelers who need to move and align objects or mesh parts precisely using geometry and measurements from their scene.
Mesh Align Plus is completely free to download and use.
Mesh Align Plus is compatible with Blender 4.2 LTS and newer. Version 1.1.0-rc.1, published in July 2024, is a release candidate built for Blender's new extension system, and it requires no special permissions to run. It operates in the 3D View across modeling, mesh, and object tasks. If you're on an older Blender release, check the developer's page and wiki for compatibility details before installing.
Mesh Align Plus can be installed by dragging and dropping it into Blender, or by downloading the extension and using Install from Disk in Blender's preferences. It's distributed as an extension for Blender 4.2 LTS and newer, needs no special permissions, and ships as a small package of about 88.2 KB. For step-by-step guidance, the developer's wiki and YouTube clips walk through the basic pick-features-then-apply workflow.
Mesh Align Plus is listed here as free and is released under the GNU General Public License v2.0 or later. For current licensing terms and any usage conditions, check the developer's page and wiki. The add-on requires no special permissions and can be downloaded directly to install in Blender 4.2 LTS or newer, either by drag and drop or by using Install from Disk in Blender's preferences.
Mesh Align Plus lets you pick features from any object in your scene, so you can align surfaces or lines that belong to separate objects. You can even define a flat surface using three verts spread across three different objects, and the order in which you select those verts matters. From there, you choose whether to move a single object, several selected objects, or a mesh fragment while modeling.
