Picking Tools
Picking tools provide a convenient way to change the position or the orientation of certain entities, such as Smokebombs, Tracer Particle Generators, Point Probes, or the wind direction. These tools, called Pick and Slide, Pick and Move, and Rotate about Axes respectively, can be found in the Tools menu in the main window or in the tool bar as shown below.

Pick and Slide
This tool applies to Smokebombs, Tracer Particle Generators, and Point Probes. To use it, you can select it from the menu or click its icon on the tool bar. Then you can pick the entity from the viewport and drag the mouse with its middle button pressed down. The position of the selected entity will then move along the X, Y, or Z axis of the world coordinate system. Once you release the mouse button, the selected entity will be updated to its new position.
Pick and Move
Similar to pick and slide, this tool applies to Smokebombs, Tracer Particle Generators, and Point Probes. With this tool, however, you can move the selected entity to an arbitrary position in the world coordinate system.
Rotate about Axes
This tool applies to the wind direction actor – the arrow in the viewport that shows the direction of the incoming wind to the Domain. Once this tool is applied, you can pick the wind direction arrow and rotate it about the Z axis of the world coordinate system. You can see that both the direction of the arrow and the orientation of the Domain will change while you drag the mouse with its middle button pressed down. Once you release the mouse button, the wind direction, as well as the Domain orientation, will be updated accordingly.
