Which tool is used to transform all vector paths within a layer?

The Layer Transform Tool is specifically designed to transform all vector paths within a layer simultaneously. When using this tool, users can move, rotate, scale, or skew the entire layer, affecting all the vector paths contained within it in one action. This is particularly useful for making comprehensive adjustments to a layer without needing to select individual paths one by one, thus streamlining the animation and design process.

In contrast, the Selection Tool allows users to manipulate individual vector paths or points but does not affect the entire layer at once. The Brush Tool is primarily used to create or edit raster-based drawings rather than transforming vector paths. The Resize Tool is focused on resizing elements but lacks the broader transformation capabilities that the Layer Transform Tool provides. This context highlights the unique function of the Layer Transform Tool in relation to the other tools available in the software.
