Multiple Buffer creates several buffers around the same input geometries in a single operation. Use it to model proximity rings (e.g. 100 m, 250 m, 500 m around a substation) without running the standard buffer node multiple times. Buffers can be entered manually or generated by linear or exponential progression.
For a single buffer, see the Buffer workflow node instead.
Open the tool
Open the right-hand panel, switch to the Tools tab, and select Multiple Buffer.
Inputs
- Create buffers around… — one or more vector datasets with points, lines, or polygons. Multi-select is supported.
- Buffering type — how the buffer distances are generated:
- Manual — enter each buffer distance individually and click Add.
- Linear — auto-generate distances spaced equally between a start and end value.
- Exponential — auto-generate distances increasing exponentially between a start and end value.
- Buffer distance (Manual) — distance in your workspace unit; click Add to push it onto the list.
- Start distance / End distance / Number of steps (Linear, Exponential) — define the range and how many buffer rings to create.
- Dissolve output to a single geometry — when enabled, all buffer rings are merged into one geometry per ring.
Run
Click Run to compute the buffers. Output is saved as a new dataset with one feature per buffer distance.
Limits and notes
- For exponential progression, the start distance must be greater than 0.
- For linear and exponential progression, the number of steps must be at least 2.
- The active filter on each input dataset is respected.
