Tore, hopefully this'll refresh your memory...as you know, Layers are not meant to be editable, so contortions are required.
First, make a copy of the layer you want to edit and call it "LayerToEDit.gpx
" or whatever and save it somewhere...This is the one You are going to edit, and replace the old one with.
Now, "clear the deck" in the route-manager . I prefer really CLEARED per deleting everything as in method 2 but method 1, "visibility toggled" of your other stuff not wanted in the layers, works, but is clumsier
In the new version, 3.2, you can toggle visibility.(eyeball icon crossed out )but really, the first step is to check and make sure you have "Unlisted" layer waypoints. The next step is to un- toggle
visibility of all existing waypoints and
layers to NOT-visible
. Only visible waypoints and routes will be exported and that's why this method can be used, compared to older versions of O
)... make backups of routes and waypoints that you want to keep
and delete all
..(.this is the old way to edit layers)
NOW, Double-check that NO waypoints or routes are "visible" in the Route-manager-the deck
is cleared for action
NOW, you can"Import" LayerToEdit.gpx
and commence editing it. When done, "Export" it to save your changes....
Be aware that only visible waypoints and routes will be exported
EVEN SIMPLER: make a portable version of OpenCPN
for just such a purpose as this ...It would save "clearing the deck" which will be really confusing if you do it wrong...example would be: a layer is "visible" while you are editing a copy
