What this tool does
Auto Balloon balloons a drawing view in one click: one balloon per component, attached along the nearest edge of the view, evenly spaced and with leaders that do not cross. Intended for assembly drawings with a parts list.
How to use it
- Open a drawing and, on the Drawing ribbon (Tools panel), click Auto Balloon. Without an open drawing, Open a drawing first appears.
- Select the view you want to balloon; the tool prompts Select a drawing view.
- The balloons are placed right away: one per unique part, along the edge and evenly spaced, with leaders that do not cross.

Placement
Fixed placement rules of the tool.
Distance from the edge
By default the balloons are placed about 2 cm outside the edge of the view.

Spacing
At least about 1.4 cm center-to-center along the edge, so balloons do not overlap.

One per unique part
By default each unique part gets one balloon, not each instance.

Tips
💡
Works best on an assembly view with a parts list: the balloons reference the item numbers from the BOM.
