Edit Point and Line

Constructing or editing a Point object and a Line object is similar. The steps to construct a Line object are:

• Select the object type: Select the 'Line' page inside the Model page.
• Create a new line object: Type in a name in the Object field and press the key.
• Select an existing line to edit: Press the small arrow at the right side of the object field. A list of existing lines will appear; click on a name to select one. When a line is selected, all its points will appear in the left listbox. In addition, these points are selected in all image windows, i.e., these points turn green inside.
• Delete an object: clicking the 'Delete' button deletes the current line in editing.
• Add a point to line: clicking the middle mouse button on a mark in an image window adds the point to the line. You will see the point being selected (changes to green), and the point is added into the point list in the Main Window. The point is added in the point list immediately after the current point. Therefore, to add a new point after a particular point in the line, first use the left mouse button to set the point as the current point. Then use the middle button to add the new point. The newly added point becomes the current point automatically.
• Delete a point from an object: double-clicking the middle mouse button on a mark in the image window deletes the point from the line.
