The features are:
1. It is light weighted, quick and depending on MS Office Excel only.
2. Customize the lithology fill pattern based on the Excel Fill Pattern
3. Customize the lithology width
4. Automatically generate the lithological legend list based on the drillhole/section input
5. The drawn lithological column (is grouped and) can be copied/pasted to other MS Office applications, and can be changed if needed.

How to Use the Program:
1. Open the SimLith Spreadsheet. If it asks you whether to allow the Macro, you select Yes
2. Input data in the lithological input section (from, to, lithology and description)
3. Setup
    3.1 Generate the lithology legend. This step allows you to generate the list of lithology included in the whole drillhole or section.

After it is done, you should see your lithology is updated in the Lithology Column and Lith Scale Column in the Legend Section. The Lith Scale col. is used to change the width for each of the lithology in the drawn column. If you want to keep the lithology the same width in the draw, you should keep them the same, otherwise, change them accordingly. It is recommended to assign numbers to the Lithological Scale from 1.

3.2 Generate the Legend, by clicking the 2. Legend (re)gene Button.

After that, you should see lithological patterns are generated, radomly, for each of the lithology, in the col. of Fill Pattern. If the fill pattern is not desirable for some lithologies, you can change them by right click on the filled pattern, and choose "Format Shape". Then, at the fill pattern changing tool, change the forecolor and the fill pattern.

Q&A:

1. If I need to draw many drillholes, do I have to change the Fill Pattern Legend everytime? 

A: Not necessarily. If the drillholes share same lithology, then you set it up once. After you input the lithology in the lithology col., you go and draw the lith directly by click 3. Draw Lith Col.

2. Can I manually add in the fill pattern box?

A: No. The fill pattern box is created and linked to the lithology list generated.

3. Can I move the drawing all at once to other application?

A: Yes. The drawing is grouped into two groups, one is for the Lithology Col., and the other one is for the Lithology Description. Then, those two groups are grouped again into one.

If you want to break the group, right click on the drawing, and select ungroup.

Recent I found a website offering FG and PG exam practices, www.geologier.com. At this moment, it only offers some test samples and detailed interpretation of the questions. Although the functions of reivew and glossary are not available yet, the website declares that they are working on the test questions, and hopefully the full featured exams are available soon.
