Drawing Tools
The drawing tools are used to create and modify entities such as lines, circles, etc. in a drawing. Commands can be selected from the menu, toolbars or entered via the command line. Right-click anywhere in the drawing window to display a popup menu showing the history of commands launched from the menus or the toolbars with the latest command being on top of the list. Note that the command line input is not shown.
Several drawing tools require additional parameters and will provide prompts on the Tool Options toolbar. This toolbar should always be enabled. If the tool options do not appear, from the menu select Widgets -> Toolbar -> and enable Tool Options. If using the command line, the same tool options are available via the toolbar or the command line. The tools that have options are shown in the table below.

Hint
When the pointer is in the shape of an arrow, i.e. no tool selected, it is, by default, in a select mode. One can select single or multiple entities by clicking on them or select multiple entities by mean of a window:
Drawn from left to right (blue), it will select all entities fully included in it.
Drawn from right to left (green), it will also select intersecting entities.
Deselecting can be done by pressing the esc
key, or Selection Pointer from Edit menu
