What visual indicator signifies that a component has been altered outside of its assembly in the draft environment?

The visual indicator that signifies a component has been altered outside of its assembly in the draft environment is bold gray corners. This specific visual cue alerts users to any changes made to the component file beyond what is reflected in the current assembly context. It serves as a warning to ensure that the user is aware of potential discrepancies that may affect the integrity or accuracy of the assembly model. Recognizing these indicators is crucial for maintaining the fidelity of designs when collaborating in a multi-user environment or when working with updated component files.

While other visual cues may have their own significance, bold gray corners specifically denote the need for the user to review and potentially update the assembly to reflect any changes accurately.
