Hi dwsmith, :)

Although I have never done this, I think you can do this using the \usetikzlibrary command. Please refer >>this<< for a complete description.

Kind Regards,

Yes, this is awkward in TikZ. The link to StackExchange seems a good resource. This is also described in section 30.5.1 "Arrow Tip Markings" in PGF/TikZ manual for version 2.10. Here is a code from there.

\begin{tikzpicture}[decoration={
markings,% switch on markings
mark=at position 1cm with {\node[red]{1cm};},
mark=at position .75 with {\arrow[blue,line width=2mm]{>}},
mark=at position -1cm with {\arrowreversed[black]{stealth};}}
]
\draw [help lines] grid (3,2);
\draw [postaction={decorate}] (0,0) -- (3,1) arc (0:180:1.5 and 1);
\end{tikzpicture}
