Tadpoles with or without vector can be created and combined to libraries in
ToadCAD. If a symbol has been created with a vector line the position of the vector
reflects the Tilt parameter recorded in the data.
Editing Methods:
Usually you superimpose the Breakout Log to an Image or RGB Log to pick the
events seen in the images. To insert a new breakout pick you will start fitting a line
first:
� Select the Breakout Log (click on the log title).
� Move your mouse pointer onto the feature you would like to pick and
press the Shift key. Your cursor is displayed as a cross.
� Left click to set the starting point of a line. With your Shift key still pressed
left click a second time at the end of the breakout.
� Release the Shift key to lock the line and record azimuth, length and tilt
angle.
Please note: Depending on the Draw Mirror option set in the default settings of the
Breakout Log (Tools →Options, Logs, Breakout Log) you will create a mirror of the
line, which is shifted by 180° and recorded as well. If you want to avoid a mirror to
be drawn disable the corresponding option in the logs default settings or use a right
click to set the start and end points of the breakout line.
Changing Length and Tilt:
If the log is still selected and you move the cursor close to the start or end point of
the breakout pick you can change length and tilt by dragging the points (press left
mouse button and move the mouse).
To measure the opening angle:
� Select the Breakout Log.
� Hold down the CTRL and SHIFT keys.
� Move your mouse pointer onto a line. The cursor’s shape will change.
� Click and drag the line apart and fit it to the opening seen on screen. The
opening angle will automatically be determined and saved along with depth,
tilt and azimuth angle.
