Which feature allows you to visualize parameters and work with flexible attributes in a model?

Dynamic Blocks are specifically designed to enhance the functionality and flexibility of standard block definitions in AutoCAD. These blocks allow users to create intelligent block definitions that adapt to different situations, enabling the visualization of parameters and adjustment of attributes directly within a model.

For instance, with Dynamic Blocks, users can set parameters for size, shape, and visibility, allowing the block to change its appearance based on the input provided. This offers significant advantages in terms of design efficiency, as users can manipulate complex drawings without needing to create multiple static blocks for different configurations.

The other choices, while useful in their own right, do not provide the same level of interactivity with parameters. Drawing Templates serve as predefined settings for new drawings but do not allow for dynamic changes within a model. Tool Palettes offer quick access to various tools and blocks but lack the flexibility to visually manipulate parameters. Layer Properties are essential for organization and management of drawing layers, yet they do not provide interactive mechanisms for adjusting attributes or visualizing changes dynamically.
