[Manifold-l] conversion of points to area objects

[Colin Driscoll]

Martin, unless I misunderstand, you can do this easily with the UI.
Copy/paste the points drawing and delete the points. You will then have a
blank drawing with the same fields as the points drawing which you can name
whatever. Make sure your transfer rules are Copy/Copy and that all columns
are transfer columns. 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. If you only want the boundary,
create boundaries and delete the area content. If you want rectangles you
can create bounding boxes around each of the circles. All of this would take
a few minutes to complete.

Subject: [Manifold-l] conversion of points to area objects

Hello all,

I'm looking for a fast script solution that would take a drawing populated
with a large number of points (1000's and each having additional fields
attached) and replace each point with either a fixed radius geometric circle
or a fixed size rectangular area still with the additional fields attached.

Any suggestions? I've found VBScript particularly slow when dealing with
large numbers of objects. I'm also slightly uncertain about how to 'convert'
a point to a different sort of entity programmatically.
