Associativity: Update & Disassociate

By default, a number of operations are created disassociated. This means that the link between the parent file (server) and the child file (client) is suspended and, therefore, changes in the server part do not affect the client part. In this case, the client feature appears in the Feature Tree with the disassociated icon . This appears in a number of functions, such as Mirror Part, Cut Active, Cut Lifter, Cut Inserts, and Extract Electrode.

The Update & Disassociate option updates the client part (based on the changed server part) and then immediately disassociates () them again. This means that this option enables a temporary association between the client and server files.

The Update & Disassociate option can be used to update and disassociate geometrical features in individual or in several parts at once; see Multiple Update and Disassociate below.

In the example Feature Trees below, note that:

Depending on the function, different options are available from the popup menu.

 

The update-related options are grayed out until a Requires Update icon is displayed (signifying that the server part has changed and that the client part may need to be updated).

Example of a disassociated Cut Active client feature (see below for an example of when the Edit option is used):	Example of a Mirror Part client feature displaying a "Needs Update" icon . Note that the relevant options are now available (see Ignore Update for information regarding this option):

As mentioned above, the Update & Disassociate option creates a temporary association between the client and server files. If the server file is changed, a Requires Update icon is displayed in the Assembly Tree adjacent to the appropriate client part as shown below:

An updated is required if one of the following changes were done to the server file: A geometric change. A transformation change. A change in the parting sets. See below for an explanation of the actions to be taken. See also: Multiple Update and Disassociate Example of different mechanisms that exist to deal with associativity

To update and disassociate a client part:

The Requires Update icon is displayed adjacent to the appropriate client feature in the Tree, signifying that the server part has changed and that the client part may need to be updated.

An updated is required if one of the following changes were done to the server file: A geometric change. A transformation change. A change in the parting sets.

 

If the Requires Update icon is displayed and the client part is not activated, activate it. Once the client part is activated, the appropriate feature is also displayed in the Feature Tree with the Requires Update icon .

 

Right-click the client part in the Feature Tree to display the popup menu and:

Select Update & Disassociate.	The Update & Disassociate option updates the client part (based on the changed server part) and then immediately disassociates () them again.

Multiple Update & Disassociate / Ignore Update

The Update & Disassociate and Ignore Update options can be used on single or multiple parts; for multiple parts, the operation is executed in a top-down order. See the examples below.

Example of single part Update & Disassociate / Ignore Update

Example of multiple part Update & Disassociate / Ignore Update

Example of different mechanisms that exist to deal with associativity

In the function Cut Active, different mechanisms exist to deal with associativity.

A disassociated Cut Active feature

In the Cut Active function, if the server faces selected in the 2nd step are geometrically modified, the Cut Active feature and the client part are marked with the Requires Update icon . However, in this case, to update the client part, select the Edit Feature Tree Popup option. This option reopens the Cut Active function (enabling the appropriate edit operations), updates the client part (based on the server part), and then immediately disassociates () them.
