Collar on Surface

Check for collar location relative to a surface

Select this check box to check for the collars of a database lying on a given surface. The check is the Z variation between the collar's Z value and the Z value of the collar's XY location registered to the given surface. If this is greater than the tolerance given, or if the surface is not hit by the collar, then the validation will fail.
