Unfortunately I don’t know what to do next.
How do I pass the point, radius and sides to the command.
Sorry if this is very elementary but I can’t find where this is specified
I am not familiar with the commandline plugins, but this page http://wiki.openstreetmap.org/wiki/JOSM/Plugins/CommandLine says you should begin typing Circle at the command line and it will then ask you for the parameters. I assume select a node on the map to anchor the output to before entering the command.
Where does the command line appear? … in one of the window icons at the left (and under the windows tab) which you would click on to open?
You can select the units under preferences>map settings>ok
Edit: I need to select the ‘draw nodes’ button first, then the tapemeasure icon at the left, then click on the map, and then works as described on the web page.
I just installed in on my iMac and works as expected.
You may need to double check where you created the CommandLine folder that holds all the files from folder “JOSM-CommandLine-commands-master” that you downloaded.
