Trim Paths keeps only a window of each path, from Start to End. Animate it to draw lines on or off.
How to use it
- Choose Geo Ops ▸ Effectors ▸ Trim Paths.
- Keyframe End from 0 to 1 to draw the path on.
- Use Offset to slide the window around a closed path.
- After a Cloner, set Trim to Simultaneously to have the copies draw on one after another.
Parameters
| Name | What it does | Default/range |
|---|---|---|
| Start | Where the visible part starts (0 = path start, 1 = path end). | 0, 0–1 |
| End | Where it ends. | 0.5, 0–1 |
| Offset | Slides the window along the path. | 0° |
| Trim | Individually: every path, every copy, gets the whole window. Simultaneously: the paths are one ribbon in order. | Individually |
Tips
