Note: 

Objective of the action is to create a plane from the elements available in the model (at present objects of type line, circle and ellips are permitted). The user selects the starting object by picking on the screen. The program tries to find a path from the starting object back to the starting object. In case of several possible paths any ambiguity must be resolved with the user's help. Possible branches on an object are shown by small circles in highlight color. Depending on the current position of the cursor the resulting paths are displayed. Clicking the left mouse button activates the currently chosen path. Subsequently the program tries to continue automatically. This procedure of interaction of program and user continues until a closed path is created. Thus a plane part is created and the user can begin with the next plane part by picking a new starting object or close the action (by picking the closing list icon).
