You can use the Content Browser to store and organize catalog tools in a central location. A number of stock tools are available in the AutoCAD Architecture 2022 toolset Stock Tool Catalog. Additionally, sample catalogs contain tools with styles from the Styles drawings. You can copy these tools to a tool palette and modify them. You can also create your own tool palettes and tools in a catalog in the Content Browser, copy them to a tool palette, and retain the link from the Content Browser to the tool palette. In this case, the tool is refreshed on the tool palette when it is modified in the catalog in the Content Browser.
