Question details

The user wants to animate a line in a presentation so that one end remains anchored in place while the other end continuously tracks an object moving along a custom or elliptical motion path.

How to Make a Line Animation Follow a Moving Object in PowerPoint

Product: PowerPoint
Device & OS: not provided
Scenario: Creating advanced custom animations, such as simulating an orbit or tracking a moving target, where a connector line needs to dynamically update its length and angle during the slideshow.
Observed behavior: PowerPoint does not natively allow one endpoint of a line to remain completely fixed while the other endpoint dynamically follows a moving shape on an elliptical motion path.

Before you start

Ensure you have the Animation Pane open to manage multiple simultaneous animations, and note that native PowerPoint tools move entire shapes rather than dynamically stretching connectors during a slideshow.

Solution 1Recommended

Manually Edit Motion Path Points

Since PowerPoint cannot dynamically stretch lines during an animation, you can approximate the effect by applying a synchronized motion path to the line and editing its center points.

This method involves animating both the object and the line simultaneously. By customizing the line's motion path, you can create the optical illusion that one end is anchored while the other follows the object.

Create the shapes and the line

Insert your fixed object (e.g., the Sun), the moving object, and a line shape connecting them.

Apply a motion path to the object

Select the moving object, go to the Animations tab, click 'Add Animation', and choose a Custom Path or Ellipse motion path.

Apply the same motion path to the line

Select the line, apply the exact same motion path, and set it to 'Start With Previous' in the Animation Pane so they move together.

Edit the path points of the line

Right-click the dashed motion path of the line and select 'Edit Points'. Manually adjust the trajectory so that the endpoint nearest the fixed object stays as close to the center as possible throughout the animation.

Animation Limitations: A simple Spin animation with a zero-degree amount will not make a line endpoint independently follow an elliptical path. Precise tracking requires careful manual alignment of the motion path points.

Solution 2

Use a VBA Macro for Dynamic Anchoring

For absolute precision where the line must stretch and rotate dynamically, a custom VBA script is required to continuously update the line coordinates during the slideshow.

Frequently Asked Questions

Why doesn't my line stretch automatically when connected to a moving shape?

While connector lines in PowerPoint will stretch when you drag shapes around during the editing phase, the animation engine treats the line as a static graphic object. It moves the entire bounding box of the line rather than recalculating the connection points during the slideshow.

Can I use a Spin animation to keep one end of the line fixed?

Using a Spin animation with a custom anchor point works for circular paths. However, if the moving object follows an elliptical (oval) path, the distance from the center constantly changes. A spin animation cannot dynamically stretch the length of the line, meaning it will eventually detach from the moving object.

How do I access 'Edit Points' for an animation path?

Click on the actual dashed line that represents the motion path on your slide (not the shape itself). Right-click the dashed line and select 'Edit Points' from the context menu. You can now drag the individual nodes to fine-tune the exact trajectory.
