Pro Align Tools lets you align lots of objects at once interactively in the 3D viewport.

The Tool is designed to bring you flexible alignment options, taking advantage of the different geometric relations that exists between objects.

Select your objects
Pick a projection plane
Press Align Objects or hit Enter!

Pro Align Tools is intended to be used in Object Mode.

Interactivity is the natural state of the Tool, previewing in realtime where will objects sit after alignment while navigating, selecting, moving, rotating and scaling your objects.

The predetermined mode of operation is Auto-alignment, a fast way of picking automatically a combination of projection plane, origins, direction, orientation and depth to align your objects with a single click.

By using the gizmos, you can change the side (depth) of alignment relative to the projection plane, by selecting it directly in the 3D View.

You can also change the side by using the Tool buttons in the Sidebar. These button are similar to those in 2D applications. They just mean the negative, center and positive direction of plane normal.

The auto-alignment gizmos are a combination of 3 axes, providing an easy selection of the alignment side, and the base point.

Reference points for Gizmos
The Gizmos have different convenient base points, referring to the selected objects and the possible places at which the plane can be set.

Finer control
You can pick any projection plane and origin point of your choice at any time.

Orientation control
In 2D applications you can normally align objects in 2 main directions fixed to the screen.

With Pro Align Tools you can align objects in global, local, view coordinates, and any other user-defined orientation.

Pick from geometry
If you want to take a projection plane from the geometry of meshes, you can also do it directly in the 3D view, by pressing Shift + P, pointing to a face and clicking.

Then selecting the side you are interested in.

Align lots of objects at once
Call the tool with the shortcut: Ctrl + Alt + A
Align faster using the shortcuts: Return / Enter
Use Auto-alignments to select very fast a preset combination of origin points, projection plane and plane depth, all with the ease of a single click
Ease your ArchViz and MoGraph works by aligning very easily in global coordinates
Hold, drag and release the mouse to place a projection plane at an offset distance along its normal
Type an exact offset distance (units allowed) to move your projection plane along its normal

Use the dedicated panel at the Sidebar to tune up your alignment configuration at detail
Use 3 different panels to customize options for Direction, projection Plane and Origin point

Project objects individually or as a group

Get realtime feedback with a dynamic projection plane following your objects and colored with the axis in use
Change the alignment orientation directly in the 3D view
Choose between the axes X, Y and Z for direction and the projection plane
Set the projection plane up to 3 levels of depth within the bounding box
Use the following key spots to define your projection plane or origin point:
Origin of the World
Location of Active/Custom Object
Global/Local Bounds of Active/Custom Object
Global/Local Bounds of Selected Objects
Use up to 5 orientations for direction: Global, Local, View, Perpendicular and Custom
Use up to 4 orientations for projection plane: Global, Local, View and Custom
Use the eyedropper to pick a Custom Object outside the selection
Switch between using bounds or geometry when fitting your objects to the plane
Pick any vertex of a mesh as the origin point
Select an individual vertex as the origin point

Pick any combination of vertices/edges/faces to define a custom plane

Draw helper bounding boxes to better appreciate the spatial relation between objects
Invalid projections such as parallel ones are highlighted in red and won’t move the affected objects
Take advantage of the possible combination of axes at your disposal to align in tricky situations
Use the perpendicular direction to align at the closest distance to the plane
Enjoy a seamless experience when having hierarchies of several parented objects

Pro Align Tools provides its own set of shortcuts that will become visible once you select the Tool. Use this as a reminder of keys or as a cheatsheet.

You can expand this list of shortcuts directly in the 3D view by clicking in the label located at the top left corner of the 3D View.

Overcomed Limitations
Modifiers are now considered when calculating the alignment of objects. You may encounter some special cases when you need an extra update for a correct alignment (displacement texture changes, shape keys, drivers). In those cases, just click the Extra Geo Update in the Sidebar.
Applying deform modifiers no longer need an update to refresh the cached data. In the past it was necessary to toggle the interactive mode or to tab into Edit-Object mode to force a refresh.
The geometry of non-mesh objects can now also be used to set the projection plane and origin point based on their bounding boxes. In the past, one had to first convert to mesh.

Known Limitations

Linked objects or collections of objects won’t use their members when aligning, only the empty object will be considered. This may change in the future.
Custom origin points can now only be defined from mesh-only objects. This may change in the future.
Take care with very dense meshes. These are hard to process. They will be loaded into memory as soon as you select them. If you try to move or rotate your object, you will probably notice some lag depending on its complexity and the resources of your hardware.

Version log

v2.1.7 (Blender 3.3.0) – Bug fixing

Fixed a regression introduced with the previous update. When initializing the tool while the gizmos were hidden (when Show Gizmo button was disabled), error messages were continuously printed to the screen.
