A simple way to select several unconnected components at a time is by using the Select Rectangle tool.
The keyboard shortcut for this tool is Ctrl + left mouse button.
Follow these steps:
- On the 2D or 3D view toolbar, click the Select rectangle icon.
- Move the cursor to the drawing area. A small rectangle follows.
- Place the rectangle near one of the components you want to select.
- Click and hold the mouse button, and draw a rectangle over the components you want to select.
- Drawing from left to right produces a rectangle with dashed lines that selects all object which it touches. This is indicated in the property box as Partial select mode:
- Drawing from right to left produces a rectangle with solid lines that only selects objects that are fully enclosed within the rectangle. This is indicated in the property box as Enclosed select mode:
- Releasing the mouse button will display a yellow or purple frame around the selected objects. At this stage, while the select rectangle tool is still active, you can add or remove individual objects to/from the selection with Ctrl + left click.
- If you used the keyboard shortcut Ctrl + left mouse button, the select rectangle disappears immediately. Otherwise, press the Esc key or move the cursor outside of the drawing area to release the select rectangle.
When there are selected objects in the drawing area (i.e. objects with a purple or yellow selection frame surrounding them), you can use the select rectangle to deselect objects too. Checking the Deselect option in the property box and drawing a rectangle enables you to do a Partial or Enclosed deselect. Deselected objects are highlighted in red in the drawing area:
The symbol at the bottom-right corner of the selection rectangle will indicate whether you are selecting objects (plus), or deselecting objects (minus):
