The following examples illustrate the methodology to follow when flattening your harness:

Branch Point in the Middle of the Support/Retainer

  • This methodology is valid when using the New From and Synchronize (with mechanical constraints) extract algorithms
  • Creating a branch point in-between the entry point and the exit plane of a support is not recommended. It won't be handled by the Flatten command.
Let's have a look at this scenario:
  • If the support has been defined like this:
  • and you route a branch through this support,
  • you will not be able to use the branch point in the middle of the support, as it will not be handled when flattening.

If a branch point is too close to a support, one of the support points close to the branch point is removed from the route during flattening and an electrical curve update error message appears.

The recommended methodology is to ensure that the branch point is a minimum distance of 3% of the branch length or 5mm, whichever is applicable, from the support or indeed any other point on the branch route.

Start and End Points of Bundle Segments

This methodology is valid when using the New From extract algorithm.
  When routing bundle segments, it is recommended that the end point of a bundle segment is the start point for the next bundle segment. However, for whatever reason, you may have routed a bundle segment from an end point you specifically created for this purpose.

A. Two single bundle segments

For example, you were expecting the following result:

and obtained this:


  If this is the case, the workaround is to isolate the connection and flatten the bundle segment.


B. Two bundle segments routed from a single bundle segment

  The above case is not handled when flattening. The workaround is to flatten bundle segments separately by selecting both bundle segments (partial flatten).
