Advanced Logic Technology sa - page 4 LithCAD v5.4 Advanced Logic Technology sa - page 5 LithCAD v5.4 Getting Started The following guide introduces the user to the essentials of the LithCAD application: + Opening an existing dictionary (*.lth file) + Copy and pasting from existing dictionaries + Editing the design of an existing symbol + Saving the pattern dictionary + Adding a new pattern Opening an existing dictionary • Start the LithCAD application and open the File menu. • Click on Open and the File Open dialog box will be displayed. • Ensure the file extension is set to *.lth • Navigate e.g. to the C:\Program Files\Advanced Logic Technology\WellCAD\Dictionaries\ folder (this is the default installation path which may be different if you have chosen to customize it during the setup). • Open e.g. the Default.lth file. Each dictionary will open in its own window. Editing the design of an existing pattern Each row of the spread sheet shows the definition of one pattern / symbol consisting of: • Row number: It is automatically set and defines the position of the litho pattern within the dictionary (former sort code). To change the order simply drag the row to its new position. • Code: Used as data value of the displayed bed or symbol in a Lithology, CoreDesc or Strata Log. • Pattern: Preview (low resolution) of the graphical representation of the pattern or symbol. • Associated Color: An alternative solid color fill that can be displayed instead of the graphical pattern (toggle display within the corresponding log in WellCAD). • Repeated: Indicates whether the symbol will be displayed repeated to form a continuous pattern. If left unchecked the symbol will be displayed only once. Advanced Logic Technology sa - page 6 LithCAD v5.4 • Name: Description of the symbol / pattern shown in legends and dialog boxes. Left click in any cell of the spread sheet to select the entire row and corresponding symbol definition. • Left click in the Code cell of a row. Change the code to any alpha-numerical code by typing the characters and numbers into the cell. The code is the "data value" stored in the log's data table. • From the Drawing or Tools bar select a color and the drawing tool. Move the cursor into the symbol preview on the right and edit the design with the selected drawing tool (e.g. hold down the left mouse button and add a line, box, etc.). • Click into the Associated Color cell and extend the drop down color picker. Select the color that will be used as alternative color fill when patterns are not displayed (i.e. the user checked the Associated Color flag in the logs Main Settings). • Check the Repeated option if you wish to repeat the symbol design to form a continuous pattern. • Left click into the Name cell to edit the description of the symbol. Adding a new symbol or pattern Insert a new symbol definition (i.e. a new row in the spreadsheet) by clicking on the icon in the Main Tool- bar. A new row will be inserted below the currently selected row or below the last row if none is selected. E.g. to insert a new entry below row 5 click any cell in row 5 to select it. Click the Insert New icon from the Main Toolbar or select Edit > Insert New and a new row will be inserted.

Advanced Logic Technology sa - page 7 LithCAD v5.4 • Select the attribute definition you would like to copy by left clicking on the corresponding row number. To select multiple row keep the CTRL key pressed while selecting the rows. • From the Edit menu select Copyor use the short-cut CTRL+C. • In the tab you would like to paste the copied definitions select the row after which you would like to insert the new rows. • From the Edit menu select Paste (or use CTRL+V). Saving the litho dictionary Before saving the dictionary ensure the Dictionary Name has been set. The dictionary name will be shown in the WellCAD Log later identifying the currently loaded litho dictionary. You may also want to think about pro- tecting the dictionary. • To save the dictionary simply open the File menu and select Save or Save As.

A new window will be added to the LithCAD workspace. • Enter a name for the dictionary into the corresponding edit box on top of the window. Note: This is not the file name. The dictionary name appears in the log's properties as identifier of the loaded lib- rary. Do you want to: Design new symbols using LithCAD drawing tools or Import symbols from files. Designing new symbols using LithCAD drawing tools • From the Edit menu select Insert New to add a new row to the editor. Advanced Logic Technology sa - page 11 LithCAD v5.4 • In the Code column enter an alpha-numerical value identifying the feature you would like to describe. This code will be used in the log's data table or when exporting data out of the log later on. • Decide on the Associated Color which will be used as an alternative color fill if the user decides to skip the pattern display. Click into the cell and select a color from the color picker. • Check the Repeated option when the symbol you are about to design should be repeated to fill an entire depth interval. Leave it unchecked if the symbol should be displayed only once. • In the Name column enter the full text description of the geological symbol as it will appear in dialog boxes and header legends. • Before starting the design define the size of your symbol. To do so select the Pattern Size option from the View menu (or click the corresponding icon in the toolbar). Enter the desired cell size and click OK. The drawing window on the right will be refreshed to reflect the selec- ted size. Please note that the cell size is measured in 1/10 of millimeters. A cell size of 50 x 50 would result in a 5 mm by 5 mm cell being repeated. Depending on symbol and pattern design the cell size needs to be adjus- ted. • It may be helpful to display grid lines and have the drawn shapes snapping to the grid knots. From the View menu select Grid Settings (or click the icon). • Enter the desired grid step and enable the option to display the grid lines in the drawing window.Click OK to close the dialog box. Advanced Logic Technology sa - page 12 LithCAD v5.4 • To enable the snap option simply select Edit > Snap or click the corresponding icon in the toolbar. • To design a pattern select a background color first.
