I want to see which parts of my map I've covered in print layout. In AutoCAD I draw a rectangle to the extents of the viewport and then CHSPACE (which transfers the rectangle to the modelspace scaling accordingly. That way I can see (in the main workspace) what is covered by a print layout and what isn't.
I'm trying to show a route along multiple print layout views (so I can plot at a usable scale). Currently I'm just eyeballing where one print layout frame starts and the preceding one ends.
I've tried google but as you can tell I'm having trouble making it clear what I'm asking.
I'd quite like to crop everything not covered by a print layout. Hopefully it'll speed up the drawing a bit.
Also is there a repository of sample drawing frames/templates? I can't seem to find anything online. Only this: https://github.com/nationalparkservice/nps-qgis-map-templates/blob/master/README.md
