10 Click in the center of the drawing area, and move the cursor to the right.
Notice that the dimension snaps at 1000 mm increments. If it does not, zoom out until it does
so.
This kind of dimension is called a listening dimension; it refers specifically to the dimension
that appears while you are in the act of sketching. The listening dimension reacts to the
movement of your cursor and to numerical keyboard entries.
TIP To zoom while in the act of sketching, use the wheel button on your mouse. If you do not have
a wheel button, you can right-click and select a zoom option from the context menu. While sketching,
you can also use the zoom shortcut keys such as ZO to zoom out.
11 While sketching a generic straight wall, zoom in until the listening dimension snap increment
shifts to 500 mm.
This is the increment that you added previously.
Sketch without snapping
12 While sketching the wall, enter the shortcut key SO to turn snaps off.
Notice that when snapping is turned off completely, the listening dimension reflects the exact
length of the wall as you move the cursor to the left or right.
13 Click to set the wall endpoint.
14 Click in the drawing area to start a second wall, and move the cursor to the right. Do not set
the wall end point.
Notice that snapping is once again active. When you use shortcut keys to control snapping, the
command is only active for one click of the mouse.
