Click the Draw | Shape | Unconformity command to draw an unconformity line in the view window. An unconformity is a collection of one or more connected line segments. The lines are wavy. Usually this line type is used to show unconformable surface contacts in a cross section view or borehole view. You can choose a line style, color, and arrowheads for the unconformity display. The amplitude and wavelength of the line can also be set.
Unconformities contain unconformity and line properties. You can change these properties in the Property Manager.
To draw an unconformity:
Click the Draw | Shape | Unconformity command to begin drawing an unconformity.
In the view window, move the cross hair pointer to the location of the first vertex and click the left mouse button.
Move the pointer to the next vertex along the line and click again.
Continue this process until you click the final point for the unconformity.
To end the unconformity, double-click on the last point or press ENTER on the keyboard.
Press ESC on the keyboard to end drawing mode.
Click the endpoints of the unconformity to draw a wavy line that various uniformly along the entire length of the line, or click several points to create an irregularly shaped wavy line.
Click the right mouse button to remove the last drawn point. Repeatedly clicking right mouse button removes all points in reverse order.
Click and hold the left mouse button to create a continuous stream of vertices as you drag the mouse.
Press the CTRL key on the keyboard to constrain the points to 45-degree angles.
To cancel drawing an unconformity, press the ESC key before ending the unconformity.
Edit the selected unconformity properties in the Property Manager.
Set line property defaults through the File | Options command.
Sharp changes in direction for the unconformity line bends the unconformity along the center axis. Connections for the waves will bend, which may result in jaggedness.
