# Arranging Branches in an Equal Angle Pattern

This task shows you how to arrange branches at any one junction at equal angles to each other.

It is recommended that the flatten algorithm mode be set to Coarse.

1. Click Equal Angle in the Arrange Junction toolbar.

2. Select the branch around which other branches will be arranged near the junction you want to arrange.

 This branch is referred to as the fixed branch. A preview highlights the junction and shows how branches will be arranged.
3. Click anywhere in the geometry area to accept the arrangement.

## More about Equal Angle Patterns

The solution you obtain will be slightly different depending on whether the junction:

• Is formed by bundle segment ends
Or,
• Is built on a branch point.

### Junction Formed by Bundle Segment Ends

The angle between branches is computed as follows:``` 360° / (Total number of connected branches at junction).```

Note: The fixed branch is counted as a branch.

Two branches: Four branches: Five branches:

### Junction Built on a Branch Point

The proposed solution depends on whether or not the branch containing the branch point is selected as the fixed branch.

• If the fixed branch is the branch containing the branch point, the two bundle segments making up this branch are positioned at an angle of 180°.

Branches on either side of the fixed branch are then arranged at equal angles with respect to each other.
Note: The fixed branch is not taken into account.

The angle between branches is computed as follows: ``` 180° / (Total number of connected branches on one side of the fixed branch + 1).```

• If the fixed branch is not the branch containing the branch point, the branch containing the branch point is split into two at the branch point. A message informs the user who must confirm the action. The junction is then arranged like a junction formed by bundle segment ends.
Note: The branch cannot be split if wrapped by a protective covering.
