Inserting a node into a polygonal entity

Into any entity (polygonal or single-segment one) an inner vertex may be inserted. The inserted vertex may be used as a node for further geometrical manipulations. For example, another entity may use it as its end-point, the node may be moved to modify the shape of the original entity, etc.

The procedure for the definition of an inner vertex

1. Start function Insert node:

   1. either call menu function Modify > Polyline edit > Edit polyline – Insert node,

   2. or click button [Polyline edit ] > [Insert node into polyline] (> ) on toolbar Geometrical manipulations,

2. Select the polylines where the inner nodes (vertices) should be inserted.

3. Press [Esc] to end the selection.

4. Define the points where the inner nodes should be located.

5. Press [Esc] to end the function.

6. The nodes are inserted into the selected polylines in the defined points.

Note: If any entities have been selected prior to calling this function, the function itself does not require making of any other selection. The function is applied on the selection made beforehand. Only the points for the inner nodes must be then specified.
