Select the model before applying the function.
You can modify the Dimensions of the model either numerically, by entering the values in the text boxes or graphically, by using the arrows shown around the model. The parameters of displacement (dX, dY, dZ) refer to the axes of the wind tunnel: dX is the axis in the wind direction, dY the one transversal to it, while dZ represents the vertical axis. If the dimensions are entered manually, the center of gravity is retained when resizing.
Alternatively, you can resize the model in the work window by selecting one of the arrows and moving it. The corresponding parameter is shown in the "Current Value" and "Step" boxes of the panel. There, you can also set the interval Δ for the model to snap on when moving the pointer. To deactivate the graphical tool, click the empty space in the work window.
