Specify the dimensions of the actual canvas. You can't reduce the canvas size to less than that of wells unless you click Trim model below, but you can reduce the display range to hide portions of the model.

Type the total number of traces to display.

Type the depth increment used for the depth model. This value is defined by your current default file, not the individual wells on the depth page. The depth increment of individual wells is specified on the Well properties dialog box .
High-frequency models work better with smaller depth increments, but smaller depth increments also affect system performance.

Click to display the Trim depth model dialog box and specify the zone of interest above and below which to remove canvas.

Click to trim the model to the display range specified below.

Type the zone of interest to include in the model. You may want to trim models when importing them instead of reducing the display range because superfluous data can affect system performance.

Type the geographic distance represented by each model increment and click Font to change the scale text display properties.

Select the label frequency from the drop-down list.

Click Font and specify the display properties for correlation names that appear on either side of the vertical scale.

Select a node size from the drop-down list. If drawing geological anomalies with correlation lines, you may want to increase the node size to see what affect the anomalies have on adjacent time markers when you flatten and unflatten the model. You can drag nodes.

Select a correlation upon which to flatten or click None.

Click to align the start and end points of a correlation with the adjacent correlation nodes that appear within the canvas borders.

Select whether depth traces are based on transit, density, or impedance. For example, if your density log is inaccurate and there's little velocity contrast,  select Transit, but for horizons with high density contrast, for example, limestone over porous dolomite, select Density.

This setting is based on the settings in the Display Parameters: Global tab.

Select whether to display every trace or every second or third trace to determine how velocity field is being interpolated.

Specify whether the underlay is based on color values or lithology. You configure lithology on a zone by zone basis using the Edit Zone Parameters dialog box . Generally, the Range check box should be cleared so you have more control over the depth model presentation.

Select whether arrows that indicate the direction in which the impedance field was interpolated appear on the depth page.

Select the frequency of depth markers.

Select whether the crossplot appears on the depth page or is hidden.
