Select by Rectangle

Documentation | Help File | UI | 2D Mode | Menu | Select | Select by Rectangle

Clicking on the Select/Select by Rectangle menu item activates the Select by Rectangle selection method for the Map area. The Select by Rectangle selection method is used to select a shape or multiple shapes contained in the currently active vector layer (the one highlighted in the Legend) that are in a predefined spatial relation with the user drawn rectangles. The spatial relation model can be selected from the Select type list.

  3. Click on the Select/Select by Rectangle menu item.
  4. Within the Map area click on a point appropriate to the selection model and location of the desired shapes - this fixes the starting vertex of the rectangle diagonal.

  6. Click again to finish drawing the rectangle.
