Many of the Constrain, Construct, and Calculate tools require that you select more than one object.
To select more than one object:
- Click the selection arrow
on the Tools panel on the left. - Hold down the CTRL or SHIFT key as you click the objects you want to select.
If you click the wrong object while holding down the CTRL key, click it again and it will become unselected.
If all of the objects you wish to select fall within a rectangular region, you can use the selection box:
- Click on the selection arrow on the Tools panel on the left.
- Draw a rectangle around all of the objects by clicking and dragging.
If you are using Mechanical Expressions on a Smartboard, turn on Smartboard mode to make multiple selections without using the Ctrl or Shift keys. In this mode selections accumulate. Clicking a blank space in the drawing does not clear the selections. Clicking on an item a second time unselects only that item.
