[Geomedia-l] Geomedia Webmap: cutting off (clipping) geometries

[R Schwantes]

I've cut lines at a the boundary of an area feature before, here are
the basic steps I used.

- Create a record set using  the CustomDataUtility and
GetOriginatingPipe this contains a record to do the cutting.

- Again using CustomDataUtility create a second record set that
contains the records that needs to be cut

- Use a Spatial Difference pipe to preform the cutting.

I realise that this is only half way to what you asked, but perhaps
the same sort of logic can be used to cut features against each other?
