We have the methods to find polygon areas (simple, means no edge intersection/crossing).
For generic contours, we also have methods to get the their areas(limitation: closed contours, no self-intersection/edge crossing.) The contour may have complex topologies, meaning support for islands in lakes over islands.
With the available tools, we need to implement GUI support.
One idea is to add an area field to the hatch property dialog. However, the current design of LibreCAD-2 makes it difficult to automatically update a hatch (and its area) following edge changes.
Is there a better way of dimensioning a polygon area than using the Info tool to get the Polygonal Area and then entering the value as text?
How about also using cows (ie 1.6m²) area units?
It would be nice if it automatically updated if the polygon changed, or the units changed to calves (ie 1.3m²).
