2.3.b.2. Draw and measure geometries

Once the Drawing Toolbar is activated, you can draw geometries of three types: polygonal, linear and punctual.
The geometries are drawn in the Working Layer that is currently in editing, by default will be the “Drawing” layer. IMPORTANT NOTE: If the display of the Editing Work Layer is disabled, geometries can be drawn but will not be displayed:

The drawing toolbar allows you to select the geometry type using the following buttons:
 Point Geometry, displays a submenu of polygon types:

  •   – Rectangles with adjustable dimensions
  •   – Squares
  •   – Polygons
  •     – Freehand
  •   – Circles

Linear geometries, displays a submenu of line types:

  •  – Lines
  •    – Freehand
  •  – Arcos

Point Geometries, displays a submenu of point mode modes:

  •    – Draw Points
  •   – Show / Hide Point Coordinate
  •   – Show / hide halo
  •   – Change the icon model representing the point.

Once the drawing tool is selected, the cursor will be in the shape of a cross indicating its position coordinate.

The shape of drawing is based on clicking to insert vertices in the geometry, in the case of polygons you can simply click on the corners:

When drawing, you will dynamically display the area of ​​the drawn polygon.
In the case of lines by clicking on each point on the line:

When drawing, you will dynamically display the length of the drawn line.

Once the drawing of the geometry is completed, it will include the measurement of its area in the case of polygons, its length in the case of lines and their coordinates in the case of points, in the units determined in the Unit of Measure Tool .

When drawing, the cursor moves closer to less than five pixels from a vertex of any other geometry already drawn (snap distance), it will be automatically reset to match it. In this way the system ensures that very close geometries adjust their edges exactly.
