Scaling and Panning the Control Window

Resizing The Control Window

To increase the overall width of the Control Window, click-drag on the vertical splitter that separates the controls from the work area and displays. Most controls will resize together with the window. This allows for greater precision with sliders, angles and other tools.

The controls have a minimum width of approximately 280 pixels. They will begin to be cropped rather than be resized past this point.

Panning the Control Window

The control window can be panned up or down to reveal portions which have scrolled out of the visible portion of the screen. To pan, either click drag on the scrollbar that appears to the right of the control window, or hold down the middle mouse button and drag while the mouse pointer is positioned over the control window.
