I just want to learn how to make graphics in TeX. I have looked through this site and tried some TeX source file. But I am confused by the TikZ and tkz packages. Do they have any relation or are they completely different?
In my daily work, I draw 2D graphics. It is about general arrangement of buildings. For example:
|-----------|-----------|-----------|-----------|
|-----------|-----------|-----------|-----------|
|-----------|-----------|-----------|-----------|
|-----------|-----------|-----------|-----------|
All the lines are axis lines. Columns are placed at the intersection. Beams are placed at all the lines. Beam lines will be offset to both side based on the axis line. For this kind of graphics, which package is the best choice?
