To Define the Section Type
If you selected the Sections method for filtering out raw data from the Raw Data dialog box, continue the task as follows:
1. Select the type of sectioning as follows:
◦ To create sections using a series of planes parallel to the reference plane, click 
. Click the selection arrow, select a reference, and type the number of sections. You can select one of these objects as a reference:
. Click the selection arrow, select a reference, and type the number of sections. You can select one of these objects as a reference:A plane to create sections. A red arrow shows the direction of sectioning.
A linear curve, edge, or axis, defining the direction of sectioning.
A coordinate system, defining the direction of sectioning. Select the x-, y-, or z-axis to define the direction.
◦ To create sections using selected datum planes, click 
. Click the selection arrow to select planes and click Done Sel.
. Click the selection arrow to select planes and click Done Sel.◦ To use a set of planes, equally spaced and normal to a selected trajectory, click 
. Click the selection arrow and select a curve to be used as a trajectory. Type the number of sections.
. Click the selection arrow and select a curve to be used as a trajectory. Type the number of sections.2. Define the Point/Section Spacing as follows:
◦ In the Proximity Zone box, type a value for the width of the zone that goes along the length of a section. Scan Tools processes data points that lie within that zone to create scan curves.
◦ In the Points Tolerance box, type a value for the distance between points.
3. Click Preview or OK.
