NTG, you can
This isn't about automatic but is need to know...
These navobj files of which you speak.... What do I do with them?
copy the navobj.xml file right back into a new install of opencpn.it's ugly though, and safetySam says, rename the original something.
BUT BETTER is:
" to ".gpx
" and save them with a creative name ...say perhaps, a date or place or the word "backup". in it.
Otherwise, you will for sure overwrite the old one you forgot you really should save with a new one you don't. But there are more backups too.... xml.1,xml.2,xml.3 etc.You can look at each one of them easily by using the above renaming process...
Assuming you have found it browsing with a file manager on your Personal Computer (or even Android) copy navobj.xml to somewhere you will find it again
Then, highlight the copy
with your mouse right click and choose "Rename" (or improve your tweaking skills- highlight;tap the F2 key...)
Type over the name with something like :"BackupRouteManager-Aug11-2015.gpx" or just "RM1.gpx",RM2.gpx,RM3.gpx ad nauseum.
No doubt some AnxietyMessage appears, "Are you sure you want to do this?"
Yes, you do.
When you want to see it on OpenCPN simply click the route
GPX button -there at the bottom of RM's window- and browse to the place on your computer you remember you put it....
Whatever you import
get's written to navobj.xml...it contains everything you find in the route
manager. ... see about "layers" in the manual-if you are not sure you want it "written in", layers are the way to go. You can Look at it first.
but BEST is a little input from you.
....You may notice there's an Export Selected Button nearby at the side
of the window....this button becomes available when you click (=highlight) on a track, route, wpt/mark .
This is very selective and allows you to export just the highlighted item as a ".gpx "file. Like your track, for instance. You could do this anytime of the day when you think you want to save something. You should
do this as soon as you can after something wildly interesting has happened. It's pretty much a log entry.
Not done yet. : Look back beside that import button and you see a Export All Visible button.
This one exports everything "Visible" from RM that you see on opencpn. What do you see? everything with the eyeball open. And that is what get's exported, as a single
inclusive ".gpx " file. You might not want to export everything, so click the eyeball and an X makes it invisible on the chart AND it won't be exported...
So, to sum up,
copying navobj.xml is a backup you can copy back to a new install of opencpn BUT it's better if you "import" it after renaming it.
items, your track for instance can be very quickly exported whenever you want with "Export Selected". and of course imported again.
Multiple Selected items can be Exported to a suitable place as a Package that describes a cruise
, a day, or a place.
Everything you import gets written into navobj.xml....it's a pain if you don't want Everything and takes awhile to clean up if there's suddenly a bunch of useless routes cluttering the screen
. They have to be deleted one by one....Sooo, It is is a good idea to read the manual about "Layers" which could be your saved stuff from earlier trips that won't
get written into navobj.xml but are visible when you want them to be...You can make the layer invisible with a single click on eyeball so it keeps the screen
"clean" and only what is new when that's all you want to see.
