"Viewer" allows the user to inspect the content of an Entity listed under the Explorer Interface its contents Opening.
Relation to Designer
We often reuse the Designer Interface as a Viewer component for the equivalent entity type. The two have similar external appearance, but differ in the functionality that they provide in terms of the possibility to edit the entity. Some of the components of Designer can be omitted or disabled when it is reused as a Viewer. Minor adjustments to the entity may still be possible in Viewer, depending on the entity type.
Specialized documentation pages on the Viewer are available for Materials, Workflows and Jobs respectively.
