I made two arrow symbols: arrow and arrow45.  With these two and the 
invert (ei) and rotate (er) commands, I am able to draw mechanical 
drawings where the arrows are used for dimension lines (arrow) and item 
pointers (arrow45).  These arrow ends are on the grid, so adding more 
line is easy.  To help with the item pointers, I also created a 
"cartouche" symbol, which has a default item number visible attribute 
(xx) inside.  Changing the default "xx" to the desired item number is 
done with the edit attribute (ee) command. The round cartouche ends are 
also on the grid, so lines can be drawn from them to the appropriate 
arrows.  I use these extensively for creating mechanical drawings for 
projects using gschem.

It certainly would be nice for gschem to rotate arbitrarily, just as I 
would like to be able to specify line coordinates on the command line, 
i.e: l x,y x2,y2.  However, I also understand that is somewhat out of 
the scope of the program, just as my using it for mechanical drawings 
is.  But my excuse is that gschem is a nice and simple drawing tool that 
I am familiar with and I have not yet discovered something else that is 
a simple to use 2D mechanical drawing tool as gschem is.

Hope this helps.
