<DIV dir=ltr align=left><FONT face=Verdana size=2>Hello - <BR>I know there have
been several posts <SPAN class=401232315-20062006>on ESRI's Users Forum
</SPAN>regarding taking borehole data into ArcScene to create a 3D soil layer
and I have used the answers in these posts. However, I have run into some
problems. <BR><BR>My final goal is to create a 3D soil layer in ArcScene so we
can visual see where certain types of soil are located in a hill. <BR><BR>Ok I
took my borehole point location data and set up a field that gives the depth to
my clay and another field to the depth to my sand. I then created a TIN from
this using the clay field as mass points. Since I am not sure if this is the
correct method, I also did an Interpolate to Raster/Kriging again using the clay
field. <BR><BR>Now taking my data into ArcScene. I extruded my borehole points
to the depth of clay field. I set the base heights of the TIN to itself and the
base heights of the Kriginig to itself as well (obtain heights from surface).
<BR><BR>Problem is that the TIN and Kriging layers line up with each other but
not to the extruded borehole points. The bottom of the extruded points is much
higher up than the TIN and Krig layer. Why? Any thoughts. <BR><BR>I assumed
since the TIN/Krig where based on the clay field from my borehole point data
that when the points where extruded to the clay field (same exact numbers)they
would line up? <BR><BR>Also which method is the best to use to create the visual
clay layer that I need to show? TIN, Kriging, IDW etc? I obviously will create
the same for sand layer as well. <BR><BR>Thanks -
