Jullie weten dat er een experimentele JOSM is
waarin rechthoeken mooier gaan ?
================
Hi,

   we have talked a lot about putting some sort of CAD-like "drawing
functions" into JOSM. The most important use case for these is
creating true rectangular shapes.

There are many ideas how this could be done, and most have some merit.
I have implemented one of these to play around with and get an idea
how it could work. This method works a bit like Google's "sketchup"
tool which is relatively user friendly.

Download the experimental JOSM version from here:
http://www.remote.org/frederik/tmp/josm-with-extrude.jar <https://ce-test.info/exchweb/bin/redir.asp?URL=http://www.remote.org/frederik/tmp/josm-with-extrude.jar> 

Now, to draw a rectangle, do this:

* first draw a simple two-node way along one of the edges of the
  building.
* select the "geometry" tool on the left hand side (the one with the
  triangular ruler as an icon)
* using the mouse, grab the centre of the line you have drawn and
  pull it in either direction. A rectangle is drawn.
* release the mouse. Two new nodes are inserted, and your two-node
  way is changed into an area.

The best thing about this is that you can continue to work with the
rectangle, i.e. if you now insert two nodes at one side of the
rectangle:

o------o----o------o

and grab the middle bit and pull it up or down, again two new nodes
will be inserted into your shape.

I'm sure this will still have a lot of quirks, please tell me what
they are.

For this demo, I have created an extra mode, which is a bit sad since
we were just about to get rid of tons of mode changes. Do you think
there is good way how we could integrate this functionality into the
standard drawing mode? Currently, when in standard drawing mode,
dragging a way does nothing, so we could theoretically put this
functionality in there. This would be good since drawing a complex
building might require inserting lots of nodes and extruding lines
alternatingly. On the other hand, maybe we will introduce more drawing
functions like this extrusion and it is good to group them in an extra
mode...?

Gebruik je satelietbeelden? Ik neem aan dat er binnentuinen zijn. Je hebt van
die grote kaarten waarop je ook de binnentuinen ziet. In Almere, maar ook bij
de Rai, zie je het gebouw zelf. Helemaal sjiek. Wel meer werk.

vriendelijke groet,
cordialmente,
