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 master 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.
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:
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:
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.
See Autodesk Inventor Help for details on the overall creation and operation of positional representations.
Cable and Harness supports Level of Detail (LOD) representations so you can suppress assembly components to improve capacity and performance and simplify the modeling and drawing environments. For Cable and Harness, you can suppress the entire harness assembly and the harness part. You cannot suppress other harness objects within the harness, but you can suppress connectors that are within the harness assembly.
If a harness part is suppressed, all harness objects inside it are invisible, all cable and harness functions are disabled if the harness assembly is in-place activated, and the suppressed harness part and assembly do not update.
You can open the appropriate top-level assembly in a specific level of detail representation or activate a level of detail representation as needed. In addition to the predefined level of detail representations, you can create any number of new level of detail representations.
See Autodesk Inventor Help for more information:
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.
Using the File Open Options dialog box, you can open a top-level assembly file in a specific Level of Detail representation. If an assembly file using a different Level of Detail representation is already open, you can only make edits to the harness design in one Level of Detail representation. All other opened Level of Detail representations are locked and unavailable for edits until you save the representation. After you save, all representations immediately reflect the changes and become available for editing. If one of the representations gets edited, other representations are locked again.
Also, when you open the same top-level assembly in two different representations, and you make changes to one of them, part of the changes to the harness assembly in this representation appear in another level of detail. For example, if you create a wire in one Level of Detail, the wire also appears in another Level of Detail. The harness part does not have a Level of Detail, so the two representations share the same harness part instance.
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. You can then suppress those components or use an alternative level of detail representation, such as All Parts Suppressed.
You must select a master Level of Detail representation when creating a nailboard, or nailboard view. When creating a drawing, you can still choose a Level of Detail representation of the top-level assembly that is not the master. If the representation has any components suppressed, the drawing view represents that state.
You can also select Design View and Positional representations, so that the combination is represented in the view. After the view is created, you can edit it to change to a different representation, if needed.
If a non master Level of Detail representation of the top-level assembly or the harness assembly is being edited, the master level of detail representation for the related assemblies is locked. In this case, the nailboard is not available for editing or updating until you save the editing level of detail representation.
