Valid external curves are curves of the following types: splines, lines,
helix, spirals, splits, joins, projections, intersections, corners and connect
curves.
- Branch geometry is created using the selected curve as center curve.
- You can add branch points anywhere along the curve.
- Only Diameter and Section parameters are available.
Since the branch center curve is a predefined curve, Bend radius
and Build mode parameters are no longer pertinent and are
therefore unavailable.
- Route Definition is unavailable: you cannot modify external
curve route. To modify the branch shape, you must edit the external
curve itself.
- Since the branch is built on an external curve, you cannot add definition
points, vectors, or devices to the spine definition.
- One branch is created for each external curve. You cannot select
more than one external curve at a time for each branch, but you can
use joins and other types of curves to combine several curves.
- Electrical connections are automatically created if the ends of
the external curve correspond to the ends of the branch.
They are only created in the Branch Definition command.
If the ends of the external curve are modified, no electrical connection
update is done.
- The branch length is the length of the external curve.
