creating thickness contours (difference between 2 surfaces)

I have created 2 surfaces of a matierial that is buried, using drill hole data.  I have a surface for the top, and then a surface for the bottom of this material.  I then created a 3rd suface comparing these 2, creating an isopac contour showning the thickness of the material.  My question is this:.....is there a way to make the zero (0) contour show up?  I have a .5 contour interval, but 0 doesn't generate.  Could i be missiing something in the settings?  Thanks for any help.

What version of C3D are you using?

OK, well I know I recall seeing this issue, but I'm pretty sure it was for an older version....and now I can't find any references to it.

 

Make sure your Major contours are set to display. If they are and 0 contour still doesn't show....

Make sure your UserDefined contours are set to display. Do a Surface Analysis for User Defined Contours, add 1 range at elevation 0. You should then be able to view the 0 elevation contours.

not sure how to do the surface analysis.

Surface Properties (right click in Prospector, right click when selecting surface in the drawing, or on the Ribbon), Analysis tab, under Analysis type choose User Defined Contours, for the Range set it to 1, use the arrow to the right to 'send' it to the window below, change the elevation to 0.

Was wondering if you could help me by giving a description of how you created your surfaces from drill hole data.  I have some drill survey data of a cavern in an Excel file (depth, radial direction, and radial distance) and am tasked with finding out how to create a 3D model of it.  What format was you data in when inserted it to create the dat?  Thanks for any help you or anyone else can offer.
