Topic:
Why can't I set the start and end cdp on the reference seismic line in the Synthetic layout?

Description:
When in the synthetics application, the user clicks MB3 > Content in the 
reference seismic track of the layout.  However, the 'Start cdp' and 'End cdp' 
options are desensitized when selecting any line type other than 'Traverse'.  
How does one define the start and end cdps desired for display for lines other 
than traverses?       

Solution:
The 'Define extent' options will become sensitized only when selecting a line 
type of 'Traverse'.  When selecting a line type of 'Traverse' you can define the 
starting and ending traces for display in the seismic track.
If you want to define a range of traces for a line type other than 'Traverse', 
you can do so in the track appearance menu.  To do so, click MB3 > Track 
appearance in the reference seismic track of the layout.  The 'Seismic track 
appearance' menu will open and allow you to enter the number of traces before 
and after.  **Note:  In defining the range of traces, you are defining the 
number of traces before and after the point where the well surface location is 
projected perpendicularly onto the selected line.  (Negative values can be 
used.)
