Currently, the only way to get going with a Navgraph is to automatically generate one, and then edit it. This is a very cumbersome task, as the automatically generated graph often creates a very dense network of nodes and connections.
You then have to click on each node and delete it (Which is another feature request I would propose: selecting multiple nodes at once).
It would be easier to have to option of starting a navgraph from scratch, and customising the path from the beginning, instead of reverse engineering it by deleting whats not required of the automatically generated network.
In the image attached, i have my building that I want to create a path through, and because I scanned the externals as well, the program is trying to create a navigation path for all the outerlying topography.
Unless there is a way to start a navigraph from scratch?
