Splitting Branches

This task shows how to split a branch into two. A new branch is created.

This operation may prove useful in the context of the configuration management in ENOVIA: It allows you to prepare the transfer of a branch to another multi-branchable document.
Refer to Split and Transfer Usage.

Create the necessary branches using the DemoGS.CATProduct document.
It looks like this for example:


  1. Click Split .

    You are prompted to select the bundle segment in order to define the branch point on which you want to split.
  2. Select the bundle segment as shown below:

    The branch point is highlighted and the Split dialog box opens:
    At this step, you can choose to split the branch at the highlighted branch point or to create a new one.

    • CATIA finds the closest branch point according to the selection point.
    • In case there is no branch point available, CATIA proposes to create a new one.
  3. Keep the first option and click OK to validate.

    A new branch is created (Branchable1.1)

  4. Alternatively select On a new branch point and click OK to validate.

    You are prompted to select the bundle segment on which you want to create the branch point.
  5. Select the bundle segment as shown below:

    The dialog box opens:
  6. Enter 0.25 for example for the ratio and click OK to validate.

    The result looks like this:


    A new bundle segment (Bundle Segment 5) has been created in Branchable1.1.
After the split, the tangent continuity between the bundle segments is maintained.

How is it done?

  • Before the split, the branch 1 (Branchable 1) is composed of three segments between Connector-A3 and Connector-A1:
    Specification tree corresponding to the following route definition
  • During the split, the branch point is isolated from the flexible curve (and becomes a point with coordinates: Point.10).
    Branchable 1 is split into two branches:
    • Branchable 1, re-limited to Point.10 with two segments (Bundle segment 1 and Bundle segment 2)
    • Branchable 1.1 created between Point.10 and Connector-A1 with two segments (Bundle segment 4 coming from Branchable 1 and a new Bundle segment 5).

    Branchable 1 is tangent to Branchable 1.1 through its flexible curve.

    Specification tree corresponding to the following route definition
    for Branchable 1:
    for Branchable 1.1:
The two branches now have their own curves and parameters such as bend radius, diameter, etc. They can be edited separately for each branch.
You can split a branch even if it is covered with a protective covering.
