Crosshair display, color and width 

To use crosshairs in eTakeoff, click on Admin/ User Preferences / Drawing tab (Toolbar Interface) or Settings/ User Preferences (Ribbon Interface). Check the box to display crosshairs in the drawing window when measuring. You can also select the color and width of the crosshair lines. The selected color will be drawn over white areas of the drawing with the opposite color drawn over black areas of the drawing. You can show or hide the cursor when the crosshairs are displayed. The crosshair display can be toggled on/off using the "H" shortcut key.
