Tools in the Workspace
The background of the workspace can be white or black. When a white (black) background is chosen, all wires will default to black (white) unless a different color is specified for certain wires. The workspace color can be set by going to Tools > Preferences > Workspace tab. The color of selected wires and wire grids can be changed at any time via Edit > Wire Color in the main menu.
The width of the line used for drawing wires and axes in the workspace can be changed by selecting a Pen Width option in the Workspace tab of the Preferences dialog box. There are three levels: Thin, Medium, and Thick. Figure 1 illustrates the different combinations between the workspace color and pen width that can be obtained.
Viewing 3D Axes
To change the appearance of the X, Y, Z axes in the workspace go to View > Axes (Ctrl + A) in the main menu to display the Axes dialog box, Fig. 2. There are two types of axes, the Small Axes, and the Main Axes. The small axes are displayed in the lower left corner of the workspace, while the main axes are displayed in the center of the screen.
Both positive and negative axes can be displayed. The color of the main axes can be changed by pressing the Color button.
Check the Show Ticks option to add the specified number of ticks to the Main Axes.
Press F7 to switch between small and main axes.
Zooming the View
To zoom in or out the view of the structure in the workspace, move the mouse wheel. If you are using a laptop touchpad, you can also use two fingers, just like when zooming an image. Alternatively, you can utilize the Zoom In (Ctrl + I) and Zoom Out (Ctrl + K) commands from the View menu.
For a more specific zoom on a particular area of the screen, click on the Zoom button on the toolbar and then select the desired area by expanding a rectangle. To return to the initial view, simply click the Initial View (Home) button on the toolbar.
Rotating the View
To rotate the view of the structure around the desired axis, first press one of these buttons on the toolbar: Rotate around X, Rotate around Y, Rotate around Z, or 3D Rotation.
Then, move the mouse over the screen with the left button pressed.
The view can also be rotated by pressing the following keys:
- F1: Right-handed rotation around the x-axis.
- F2: Left-handed rotation around the x-axis.
- F3: Right-handed rotation around the y-axis.
- F4: Left-handed rotation around the y-axis.
- F5: Right-handed rotation around the z-axis.
- F6: Left-handed rotation around the z-axis.
Moving the View
The view of the structure can be moved in the workspace. First press the Move button on the toolbar and then move the mouse over the screen with the left button pressed.
Double-click on the workspace to center the view of the structure on the screen.
