For each column, either text vs depth/depth scale or plot vs depth, where do I give the expression for column bottom (ie., hole depth ) in their respective properties window ?
There is a mandatory field in the Point table called HoleDepth. This controls the depth to which an entity plots various elements if the entity is set to plot to Hole depth. You can override this in the entity by selecting Bottom of hole for the property. Depending on the entity it may be located in several different locations. some entities have more than on such property. There is usually one in the Column lines tab. The scale entity also has one in the main tab. A graph entity may have more than one as well but i did not look it up.
