MicroStation has dozens of drawing tools (or tools, for short). These tools are grouped for convenient selection in the ribbon. However, you can also open tools from toolboxes.

Each open toolbox is either floating in its own window or docked to an edge of the application window. You can change the arrangement of tools in a floating toolbox by resizing its window.

Tools are represented in toolboxes by icons. For simplicity, the term "tool" is used to refer both to a tool and its icon.
