2023.1.1571.2 Alignment Tool

Overview

This tool is used to align objects in the scene to each other. For example, aligning a screw with a hole or a surface against another surface. A shape can be drawn onto both objects, which is used to determine the translation and/or rotation one object has to make to be aligned to the other.

Where to find

The Alignment tool can be found under Utilities > Alignment Tool

This will open the following window:

Feature layout

The image below shows the complete feature layout of the Alignment tool.

Part A / Part B
Transform	Use this field to select a transform.
Alignment Color	Use to select a color for the alignment shape.
Alignment tool type	The type of tool that will be used for the alignment operation. This determines how the moving transform will be translated/rotated, and to which exact point it will be aligned. The following options are available: 3-point plane: A plane described by 3 points, with the weighted average of these points as a centerpoint and a direction perpendicular to the plane 3-point circle: A circle described by 3 points, with the centerpoint at the center of the circle and a direction perpendicular to the circle Transform pivot: A single point that is equal to the pivot of the object and a direction equal to the rotation of the object N-gon plane: A plane described by n > 3 points, with the centerpoint at the average of those n points and a direction perpendicular to the plane 2-point line: A line described by 2 points, with the centerpoint at the position of the first of those two points and a direction equal to the vector p1->p2
Advanced settings	See advanced settings
Clear Part	Clears the Transform field and resets the settings
Alignment Settings
Offset settings	Unfolds the settings for an offset vector. See Adding an Offset
Affected Fields	The transform settings that will be affected by this alignment operation. The following options are available: Position: rotates the moving transform while retaining its original position Rotation: Translates the moving transform while retaining its original rotation Position and Rotation: Rotates and translates the moving transform to a new position and rotation
Apply Alignment	Executes the alignment operation
Isolation Mode	Isolates the selected transforms in the scene. All other objects will be hidden

How to use

Drag the object you wish to align (moving object) into the Transform field
After selecting the tool type, use the handles in the scene to position the alignment shape onto the object

Press Shift+v to enable vertex snapping, which makes it easier to position the handles correctly, as seen in the example above. Don’t forget to turn off (Shift+v) when you are done with positioning the handles

Repeat this process for the destination object

Apply Alignment button to align Part A (Object to move) to Part B (Destination).

Advanced settings

Expanding the Advanced Settings gives you the following options:

Advanced settings
Invert Alignment Points	Inverts the point order of the alignment shape, flipping the direction vector of the shape.
Input Space	The space in which the alignment shape point locations are set (global/local).
Point vectors	Use these vector fields to manually set the alignment shape point positions.
Weight	The weighting factor of each alignment shape point. Use this to control where the centerpoint of the alignment shape will be positioned.
Centerpoint	The position of the centerpoint (read only).
Normal Vector	The direction vector of the alignment shape (read only).

Adding an Offset

Click on Offset Settings.
Click on the Add Offset Vector button.
To edit the vectors, click on Offset Vector n.
