The "distance" command measures distances and (by default) shows
dashed lines and the distance values in the main window. The distance
at the time of command execution is also reported in the Reply Log.
dist #0:35 at ca #1:35 at ca
You can control the appearance of those distance monitors, for example
to hide the distance values:
setattr p label " "
To show arrows, however, the only way I know aside from python coding
is to create a BILD format file describing the arrows and read it in.
The format is pretty simple. For example, reading in a file
arrow.bild containing this line:
.arrow 17.675 49.049 21.434 16.956 48.582 17.728
makes an arrow between the two sets of xyz coordinates. You can also
control its thickness, color, etc. and make other shapes, and of
course put many of them in one file. See the BILD description:
