Constructions: Insert Point

The Insert Point command calculates new point coordinates that lie exactly on the line. At the insertion point, a new vertex is inserted. The vertex indicates the relation between point and line for further processing.

You can split the line at the insertion point. The existing line feature is deleted and two new line features are created instead. Specify whether to split a line or not in the application options.

The insertion is documented in the database. An inserted point is saved with a special reliability attribute.

If the difference between the old and new position of the point exceeds the split tolerance, the point is not inserted and a message appears.

You can set the split tolerance in the application options.

You can insert a point only under certain conditions. If a condition is not fulfilled, one of the following messages appears in the command line:

• The distance from point to line is too large: You exceeded the split tolerance.
• There is no suitable point at the vertex before the point: You can insert a point only if there are points at the vertices before and after the insertion point.
• The line already has a vertex at this position: You cannot insert a point at an existing vertex.
• The spatial tolerance of the selected line must be smaller than the split tolerance: The Administrator set the spatial tolerance when creating the database.
