Basic Geometry Information

Point

Updating Point Orientation

Things That Make You Go Hmmmmm….
You may have noticed that when you insert a point or move a point using the editor that the points orientation changes. This is due to the method rwo_record_mixin.connection_changed() which orientates the point to line up with an existing point or the segment theta of the chain it is connecting with.

Areas & Simple_areas

These features contain "regions"

As with most simple "geometires" and regular geoemtries, a simple_area does not have any topology. Simple_areas can have holes, but cannot have separate polygons. You can have many holes in a simple_area, but you cannot have an island in the hole.
