G’day,
Can I ‘second’ this question! - I am trying to simplify complex
geometries, and would love a way of duplicating them so I don’t have
to rebuild the topological version every time I over-simplify…
I haven't tried this, but couldn't you do this in a big transaction and
then if you don't like the results do a rollback or commit if it looks good.

Hello,
I've created a series of topology schemas, copied using the
`CopyToplolgy` function [1].
These schemas are not, by default, associated with any particular
layer/TopoGeometry. This can be seen in the contents of the layer
table [2].
So, I'm wondering if it is possible to do one of the following: -
Create a new column of type topogeometry, and associate it with any
of these currently unassociated schemas. - Modify an existing
topogeometry column (in my example, somalia_admin1s.topogeoms)
Thanks, Matt
