Representations in Cable and Harness

Positional representations in Cable and Harness

Cable and Harness responds to positional representation changes in the top-level assembly and standard Autodesk Inventor subassemblies the same way it responds to standard assembly updates. Positional representations are not available in the harness assembly level.

When the top-level assembly is in the [Primary] positional representation, most of the Cable and Harness commands and context menus are available for use, even if one or more subassemblies contain an active positional representation. When positional representation changes occur in the top-level assembly, the available commands and context menus are limited.

What commands are available when positional representation changes occur in the top-level assembly?

Only those Cable and Harness features that help you understand and adjust the harness lengths needed to support the various positions and to ensure there are no bend radius violations are available. You can:

  • Check for bend radius violations.
  • Add and adjust harness properties.
  • Change harness display settings.
  • Generate reports.

How do flexible elements respond to positional representation changes?

The flexible objects such as wires, cables, ribbon cables, and segments recalculate to bend and update as positional representations change. These objects must be associated to existing geometry to update. For example, segment and wire work points that are offset from a face are not associative and do not update to positional representation changes.

You can add additional associative points so that harness objects respond correctly to positional representation changes. You can also redefine any non associative points onto the following geometry to make them associative:

  • Existing work points.
  • Center points on any circular component such as a face, a hole, and cylindrical cuts or arc edges.
  • Existing sketch points.
  • Model vertices.

Active bend radius checks are supported during positional representation changes. Dangling wires and harness assemblies set to defer updates do not respond to positional representation changes.

How are positional representations created and edited?

See Autodesk Inventor Help for details on the overall creation and operation of positional representations.

What happens when referenced components are suppressed?

When an assembly is suppressed, it may temporarily cause the harness objects to have errors when they reference missing components. For example, if a harness references suppressed connectors that exist either outside or inside the harness assembly, any wires or cable wires attached to those connectors will dangle at the next update. These errors are resolved once the components are unsuppressed and the next update occurs.

In certain cases the harness design does not update automatically. In these cases you can force the update by clicking the Update command or in-place activating the harness assembly.

How can I determine which components are consuming the most memory?

The Find command helps you determine which components are causing the most memory consumption. The easiest way to access the command is by clicking the binoculars symbol in the Model browser.

In the Find dialog box, ensure the Estimated Cost property is one of your search criteria, specify a value, and set the condition to is greater than. Create a View representation to turn off the visibility of those components.
