You can access this button in the tool bar,

or by going to the “Geometry” menu bar then to “Complex selection”.

When the “Complex selection” tool has been selected, right click on the mouse in the graphic area. The following contextual menu will appear.

Click on the option you wish to use to select the elements.

If you use the “Inside circle” option you can delimit a circle so that the elements you wish to select remain inside this area.

The selection result corresponds to the following image.

You can also write the “select” and “complex selection” commands in the command console. Command: “select” Write the command “select” in the command console.

When a message appears in the command console requesting you to add the selection point, input the coordinates of the object you wish to select.

If there is an object in the defined coordinates, it will be selected.

Command: “complex selection” Write the command “complex selection” in the command console and when the selection options appear, write the desired option.

The options are shown with their names, and in square brackets ([]) the text you need to input in the command console to use the option.

If, for example, you wish to select the features that are in a polygon area, you need to write “complex selection” in the command console, press “Enter” and then select the “IP” option.

This allows us to indicate the coordinates of the vertices which will make up the polygon (when the coordinates of each of the vertices are indicated a polygon is drawn in the drawing window) and when it is finished, the elements which are inside it are selected so you can work on them.

The following image shows how a selection option is input.

The following figure shows the definition of the selection polygon in the graphic area.

When the polygon is finished, the elements contained inside it will be selected so you can work on them.

Selection options

• Outside rectangle [OR]: This allows you to delimit a rectangular area and select the elements which lie outside this area.
• Inside polygon [IP]: This allows you to draw a polygon area and select the elements located inside this area.
• Intersects with/Contains polygon [CP]: This allows you to draw a polygon area and select all the elements located inside it or which intersect with its perimeter.
• Outside polygon [OP]: This allows you to delimit a polygon area and select the elements which lie outside it.
• Inside circle [IC]: This allows you to delimit a circle and select all the elements located inside this area.
• Intersects with/Contains circle [CC]: This allows you to delimit a circle and select all the elements located inside it or which intersect with its perimeter.
• Outside circle [OC]: This allows you to delimit a circle and select the elements which lie outside it.
• Select all: This selects all the elements contained in the layer regardless of where they lie in it.
