Types of Simplified Representations
Master—Reflects the fully detailed assembly. The Model Tree lists all its components and identifies them as included, excluded, or substituted. When an assembly is created, the Default representation and the Master representation are identical. You can update the Default representation to create a variation of the Master representation.
Automatic—Retrieves the minimum required data for presenting the assembly in the most accurate way. This representation uses the graphics representation as the starting representation when possible. The system then determines what data is required and retrieves it based on your actions; the geometry or master representation as needed. You can perform such actions as measuring distances between points on a surface without retrieving the part geometry. Use this representation type to retrieve your assembly as fast as possible.
User Defined—Activates a simplified representation of your choice from the selected component.
Default Envelope—Allows you to represent assembly components with an envelope. When multiple envelopes are present, you can select a default envelope for representing the selected components.
Exclude—Excludes the selected components from the simplified representation.
