Lines
When you are creating the a line double click to conclude the creation.
Polylines, curves and fronts
...
When you are creating a polyline or a curve each left-click on the map adds a new point , and double-click concludes the creation.
What kind of symbol are available?
Fitted geo-shapes
These are special shapes where all the vertices defined by a lat-lon position and the edges between them are sampled linearly in the lat-lon space. It means that in cylindrical projection the edges are always straight lines, while in other projections they might be curves. The following table shows how a fitted geo-shape changes as the projection changes from cylindrical to polar north:
| Shape | Cylindrical | Polar North |
|---|---|---|

Geo shapes
In these shapes all the vertices are defined by a lat-lon position and they are always connected with a straight line (or with a B-Spline for curves) in all the projections.
The geo rectangle is a special object because it always keeps it rectangular shape. It means that if we zoom the lat-lon positions of the corner points do not change. However, if we change the projection the lat-lon positions of the corners are automatically adjusted so that the shape could be a rectangle in the new position.
