[Manifold-l] conversion of points to area objects

[Colin Driscoll]

 >need the circles (or some other area form) in a separate drawing
That's what this step does in the original recipe:

*Make the empty drawing active in a map with the points drawing. Create
buffers of 
the desired radius and they will be created with the data from each point
coming across*

In other words when you run the buffer transform the buffers are created in
whatever is the active drawing at the time- it doesn't need to be the
drawing that the points are in.

Yes, I've got the points already in a drawing, but need the circles (or some
other area form) in a separate drawing. Thinking about this, I suppose I
could simply apply buffers to the existing points having set appropriate
transfer rules and then, having created them, exploit the fact that they are
currently selected and simply cut and paste into a new drawing!

Ah, methinks I'm being dim and have answered my own question! It's amazing
how sometimes something becomes so clear once you've tried explaining it to
someone else!
