CAD Structure Version Preferences

The Parameters button on the Model TGV toolbar provides access to the Parameters dialog with options on which versions of child CAD Documents should be retrieved from the dataset and shown in the Dynamic or in the Streaming Viewer.

As a CAD Document is a versionable Item and has the Item States, a child CAD Document attached to a parent CAD Document can have multiple versions, and the attached child version may or may not be:

• The latest
• In the Released State

To set which child CAD Document versions should be retrieved from the dataset and shown in the Dynamic/Streaming Viewer, the Parameters dialog has the following options:



• Default: only the versions of children that are attached to given versions of parents, regardless of the States of these children and whether they are the latest or not.
• Latest: only the latest versions of children, regardless of their current State and whether they are attached to given parents or not. This is the default setting.
• Latest Released: only the latest versions of children in the Released State, regardless of whether they are currently attached to given parents or not.
• Latest Released Or Latest: the latest versions of children in the Released State if they exist; otherwise, their latest versions, regardless of whether they are currently attached to given parents or not.

Both the Dynamic and the Streaming Viewer resolves the CAD Document structure according to the current setting in the Parameters dialog recursively for each branch. A child with its own children is a separate tree branch. At first, the Viewer validates the immediate children of the top-most parent (the first level), then the children of each immediate child (the second level), and so on for each level.
