To calculate angle and length |
The mode is intended for getting measures of lines and the sizes of angles. Measurements are made within the triangle. The operator specifies the points limiting it. Angular points of a measured triangle are got as a result of a choice of following combinations of objects of a map: three dot, one linear (polygon) and one dot, two polygon (linear) in any combination. At a choice of polygon or linear objects for creation of a measuring triangle that piece of the metrics is chosen, which was the nearest to the cursor at the moment of a choice of object. As a result of an execution of operation the measuring triangle will be constructed. Values of lengths of the sides and corners of a triangle (internal and external) are displayed in a dialogue window.
Description of dialogue: Corners and distances.
