INS SRF OPTION
To use the Ins Srf option
1 Follow steps 110 in Using Borehole Data to Interpolate the Surfaces for the
Cross Sections in this chapter.
When you place your cursor in a row of station values in the Interpolation
Surface Control Editor and click the Ins Srf button, the New Interpolation
Values dialog box is displayed. You can use this dialog box to enter
depth/thickness values for a specified surface.
NOTE
The Station box is grayed out. The station value is the station your cursor
was located in when you selected the Ins Srf button.
2 In the Surface name box, type the name of the next surface you want to enter
depth/thickness values for.
3 Do one of the following:
n
In the Thickness box, type a thickness value.
n
In the Depth box, type a depth value.
4 Click OK to return to the Interpolation Surface Control Editor.
Drawing Templates
You can create template surfaces using the Draw Template command or the
AutoCAD PLINE command. The Draw Template command takes the vertical
exaggeration of the drawing into account automatically. If you use the
AutoCAD PLINE command to draw the template, then you must draw the
polylines with the drawings vertical exaggeration in mind.
You can use the Draw Template command to draw both templates and
subassemblies. This command uses a 2D polyline to draw lines based on offset,
depth, grade, and slope parameters. It does not matter whether you draw the
template or the subassembly first. However, because the subassembly is attached
to the template with the Define Template command, you must define the
subassembly first.
