Extract 2D Cross Section

In order to visualize the density structure of models using vertical and lateral property distributions, GM-SYS 3D has a tool for displaying vertical cross-sections of your 3D model at any location and azimuth.

The Extract 2D Cross Section function displays a vertical slice through a 3D model with density or susceptibility displayed as a grid. Calculated and observed anomaly profiles may optionally be displayed above the section. Cursor position is displayed as model X, Y, and Z-coordinates at the bottom-right corner of the Oasis montaj window. The property section grid may optionally be displayed in the 3D View of the model.

To Extract a 2D Cross Section

Before you begin, confirm that a 2D plan map is the current map.

On the Display menu, select Extract 2D Cross Section. The Extract 2D Cross Section from 3D Model dialog appears.
From the dropdown list, select the Anomaly type as magnetic or gravity. The default is gravity.
Specify the New profile name and location. The default value is "Line_1".
From the dropdown list, select Plot surrounds to draw a box around the profile map. The default is no.
From the dropdown list, select Plot anomaly above cross section to plot Observed/Calculated Anomaly curves in a separate profile box above the density/susceptibility profile map. The default is no.
From the dropdown list, select Plot density/Susc colour bar to plot horizontal density/susceptibility colour bar above the anomaly profile box or above the density/susceptibility profile map, if no anomaly profile is desired. The default is no.
From the dropdown list, select the Method to set profile coordinates. The options are New Digitized Points or Previous Points/Manual Input. The default is New Digitized Points.
Specify the Colour zone. This is the colour zone file for colouring the anomaly grid cross section, and optionally, the horizontal anomaly colour bar. The default is colour.tbl.
Select to Plot section in 3D View. The default is no.
Select the Colour method for the cross-section grid. The options are Histogram equalization (new default), Normal distribution, linear, default,or as last displayed.
Click OK. The Extract profile dialog appears.
Using left-click(s) set the beginning and ending points of the profile.
Click OK. The Cross Section appears in a new map document.
