Break Tool

Use the break tool to break a segment out of a line object.

The Break tool is only available if the  Cross section view tool is enabled.

You can modify both straight and arched lines with this tool by following these steps:
  1. Activate the Break tool.
  2. Click on a line-object that you want to edit. TuMan marks this object and a cross-hair marking appears on the line.


    Figure 1. Breaking a line with the Break tool - cross-hair marking for the 1st break point.
  3. Move the mouse to shift the marking on the line.
    Note: If another line object near the mouse cursor or its extension intersects the marked line, then the cross-hair marking is positioned at the closest intersection point of these two lines.
  4. Click to define the first breaking point. TuMan now fixes the marking at this breaking point and displays the second marking.

Repeat step 4 to define the second breaking point. TuMan erases the line segment between the two breaking points.
Note: Circles are broken counter-clockwise, starting from the first breaking point to the second.
