Slope Stability Data Interpretation: Filter Slip Surfaces
Slip surfaces can be displayed in the Interpreter using the same colouring
as is used for the search grids (and shown in the legend). The surfaces
can also be filtered in a variety of ways, as can be seen in the image
below.

Slope Stability Data Interpretation: Plotting Surface Data
The plotting of forces on any surface of interest is easily done by
simply selecting the slice. Data such as base normal and shear forces,
slice weight and inter-slice forces are shown in relation to the rest
of the slope. Simple data export functions exist for importing data
into Microsoft Excel™ or any other spreadsheet or word processing
software.

Slope Stability Data Interpretation: Plotting Factor of Safety along the Slope
Most slope stability programs stop at showing the minimum critical failure surface. Engineers know that it is not only the minimum critical surface that must be stabilized but all possible surfaces with a critical safety factor. With Slide, it is possible to plot the safety factor along the slope surface and show all failure surfaces with a value less than some critical value. This allows for easy design of anchor lengths and stabilization methods.

Slope Stability Data Interpretation: Supplemental Contours
The interpreter can contour the results of the interpolation done
for water pressure grids and for discrete strength functions. Furthermore,
new interpolation methods have been added to Slide. The new
methods often result in much shorter compute times. Using the new
'Supplemental Contours' feature together with the new interpolation
methods allows you to assess the results of the interpolation so you
can make sure the interpolation that occurred agrees with the expected
results.
Contours of Discrete Strength function interpolation.
The strength was interpolated using 13000 data points generated from
a finite-element model. Notice the complex distribution of strength.

Slope Stability Data Interpreter: Interpreter Dynamic Text
A "dynamic text" feature has been added to the Interpreter to make
your job easier when performing sensitivity analyses or editing your
models. When you use this option, the text is linked to the document
and to the location in the image where you place the text box. You
can also mix any amount of regular text (that doesn't change) with
the dynamic text to get the exact formatting that you want (see the
image below).
Example
To create the image below:
1) a text box was added
2) The arrow head was moved into position on the green material. The arrow head
specifies the location for dynamic text that depends on the location in the model
(such as material names).
3) In the Add Text dialog, "Dynamic Text" was selected for "Type of Text", and
"Project Title" was selected out of the list.
The results is seen on the model behind the dialog. The actual project title "Non-Circular Surfaces Tutorial", which was entered in the Slide modeler, is substituted. A similar method was used to add the material name to the text box.
Uses
Dynamic Text is most useful when Interpreting many similar models
such as when you are performing a sensitivity analysis. You can add
the dynamic text, go back into the modeler, change some properties,
and when you go into the Interpreter again, the new properties are
displayed in your text box!

Data Tips
Data Tips in Slide allow the user to simply hover the mouse
over the model to obtain information about model input parameters
or analysis results. If the Data Tips mode is set to Maximum, the
user can obtain detailed information about material properties and
other model data by simply hovering the cursor over materials, support
and other objects in the model. In the example below, the cursor
is moved over the tension crack and the properties for the tension
crack (that were entered in the modeler) are shown.
A great deal of other data can be displayed in Data Tips Maximum
mode. The Data Tips mode can be quickly toggled by clicking the
mouse on the Data Tips box on the status bar at the bottom of the
application window.

Slope Stability Data Interpretation: Plotting In Excel
All charts in Slide can be exported directly into Microsoft
Excel™ with one click. The Interpreter will automatically start Excel,
export the data, and create the same chart you are viewing in the
Slide Interpreter. The data used to create the chart is also
exported, so you can adjust the chart in Excel or create a different
type of chart with the data.
Below is a picture of a chart in Slide and the corresponding
image that was created in Excel.
One click on "Plot in Excel", gives you the same chart
in Excel.
Slope Stability Data Interpretation: Drawing Tools
The annotation toolkit provided in the Slide Interpreter is extremely flexible. The wide variety of drawing objects that can be added to your document can be seen in the image below. All editing of objects can be easily done by "dragging and dropping" the objects with the mouse.
Of special note is the polygon in the center of the image. The polygon
was drawn (using vertex-snap to align with the boundaries). A text-box
was then added, and using the dynamic-text feature, the area of the
polygon is automatically calculated. If the vertices of the polygon
were moved, the area displayed in the text box would be automatically
updated to reflect the new area.

Slope Stability Data Interpretation: Favourite Text
A new feature called "Favourite text" has been added to the interpreter. The interpreter allows you to define text that you have input as "favourite" (i.e. frequently used). This feature is best explored by using the Interpreter, but once you are familiar with this feature, you will be able to fully annotate a model with a few clicks, in a matter of seconds.
Three popular examples would be:
1) Adding a standard title block (e.g. company name & address) to all of your models
2) Adding material names in various locations around your model (the material name is automatically extracted from the location on the model - no need to type in the material name!)
3) Annotating coordinates to various locations in your model.
This greatly speeds annotation of text, if you add the same text to
all of your models or need to quickly add similar text to a number
of files.

Slope Stability Data Interpretation:
Dimensioning
Dimensioning in the Interpreter is both easy to perform and extremely
flexible. As can be seen in the picture below, you are able to dimension
horizontal and vertical dimensions as well as lengths and angles.
Formatting
Formatting of dimensions is extremely flexible. For each dimension,
you can optionally remove the text, arrow heads, dimension lines,
object lines, and extension lines (the gray dashed lines). You can
also control the number of decimal places shown and whether units
are appended to the end of the number.
Text Replacement
Additional text can be added to the dimension, with or without the dimension value. For example, you could add the text "typical bench width" to a dimension. If your design changes, you simply drag the dimension into the new location. The dimensioned value (the distance) is automatically updated, but your text is preserved and moved into the proper location - saving you from having to re-type or re-align your text!

Slope Stability Data Interpretation: Quick Zoom
The Quick-Zoom feature in the Interpreter allows you to zoom all of
your models to the same coordinates with one click. This is very helpful
when performing screen captures at a specific location in your model
or for comparing models. (The models shown in the image below are
of different slopes, so it is useful to look at the ruler in each
of the four models to see that the windows are all "zoomed" to the
same coordinates).

Scale Drawings
The Interpreter allows you to print your models at a scale from the model coordinate system.
Actual Image
To create the image below, A scale of 1:100 was set in the Interpreter. A dimension was added to show the distance in model coordinates (21.9 metres). The document was then printed on our printer (an HP LaserJet 5M). The printed page was then placed on our scanner, along with a ruler, and the results are shown below, producing output that is quite close to the required 21.9 cm. Because of the wide variety and quality of printers, you should verify that your printer is producing scale drawings before using this feature.

Slope Stability Data Interpretation:
Adjustable Precision
The number of decimal places displayed is very easy to change. Simply
select the "legend options" as seen in the image below and adjust
the number of decimal places you want displayed. This setting is reflected
in the legend, all of the contour labels, and the factor of safety
for any of the slip surfaces in your model. The setting is also stored,
so you don't have to adjust it each time you start the Interpreter.

One-click Grayscale
The Grayscale option allows the user to convert the entire view to grayscale (black and white) with a single mouse click. This can be useful when black and white screen captures or printouts are necessary.

Export Image Files
The Export Image option in the File menu allows you to save the
current view directly to one of four image file formats: JPEG (*.JPG),
Windows Bitmap (*.BMP), Windows Enhanced Metafile (*.EMF), Windows
Metafile (*.WMF). Metafile images can be imported into AutoCAD.
The current view can also be copied to the Windows clipboard using
the Copy option in the Edit menu. From the clipboard, images can
be pasted directly into word or image processing applications.
