# drawing package in tex

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?

Welcome to tex.sx! A tip: If you indent lines by 4 spaces, then they are marked as a code sample. You can also highlight the code and click the "code" button (with "101010" on it). –  Caramdir Feb 8 '11 at 3:10

One of the most popular graphics bundles is PGF, which comes with a user-friedly syntax layer called TikZ. There are also a number of packages that all start with tkz as a prefix. For example tkz-2d. You can see many examples at texample
@warem yes any package with a tkz prefix uses tikz. For small diagrams like what you want to use in your calculation sheets tikz is ideal. Start from tug.ctan.org/tex-archive/graphics/pgf. –  Yiannis Lazarides Feb 8 '11 at 2:49
