Dialog box “Transforming to circle”

Purpose and description

The dialog box allows specifying parameters of the polygon modeling the circle when transforming a list of vertices into a circle in the course of adding or editing a line or an area feature.

The input field Center contains coordinates X and Y of the circle center in map coordinate system. By default the system offers an arithmetic average of all vertices of the source list.

The input field Radius contains the circle radius (in map units). By default the system offers an arithmetic average of distances of all vertices of the source list.

The input field Number of points contains the number of vertices of a regular polygon modeling the circle. By default the system offers to use 36 vertices.
