## Vector Lines Panel

The Vector Lines panel controls how vectors are displayed.

### OPTIONS

Current:
  Shows the name(s) of all the loaded vectors. You can use this menu to select a new current vector.
New
  Loads a new vector file.
Delete
  Deletes (unload) the current vector.
Line Width
  Sets the width (in pixels) of the current vector.
Color
  Sets the color of the current vector.

You can display a vector flat at a specified elevation or drape it over a surface(s) at a specified height. Use the Vect. Z scale to set the flat elevation or the drape height above the surface(s).

Display Flat
  Draws the current vector on a flat plane at the elevation set by the Vect. Z scale.
Display on surface(s)
  Draws the current vector draped over the selected surface(s) at the height set by the Vect. Z scale. A list of available surfaces appears directly below Display on surface(s). Use this list to select the surfaces for draping the vectors over. For display purposes, it is better to set the height slightly above the surface. If the height is set at zero, portions of the vector may disappear into the surface(s).
Vect. Z
  Sets either the flat elevation or the drape height above the surface(s) (depending on which option is selected).
Draw Current
  Draws the current vector file.
Close
  Closes the Vector Lines panel.
