Has anyone managed to get a working install of QGIS3, with GRASS successfully
working properly?
Could you share how you did it?
I literally just installed QGIS3 according to the ReadMe on a MacBook Pro,
fresh out of the box. First thing on the machine other than the OS.
Still doesn’t work.
Is no-one else having this issue? I’ve been trying since QGIS3 came out and
I’ve never been able to get a properly working install.
Yes, I’ve tried the Lutra Consulting installers, now, as well. Grass doesn’t
work on those, either.

"I have a map of the United States... actual size.
It says, "Scale: 1 mile = 1 mile."
I spent last summer folding it."

Hi Mike,
If you use the "Move item content" map to pan the map, you can also zoom in and
out using the mouse wheel. Or you can set the map scale in the item properties
to a defined rounded scale, which also changes the extent. This should help you
get rid of the whitespace.

Again a huge help!
When I do the "Set to Map Canvas Extent" the map in Composer looks like:
[X]
Maybe I am asking the wrong question .... would like to not have the "white
space" around the map
THANK YOU again!!!

Hi Mike,
You can't directly zoom to the inverted polygon for the display in composer.
But: you can zoom to the inverted polygon in the main canvas (Right click on
the layer in the legend tree and zoom to layer) and then synchronize the main
canvas and the view in composer.
Use this button (set to map canvas extent):
[X]
Or you can interactively pan/zoom to the extent you want with the following
tool:
[X]
First select the map element you want to pan/zoom and then use the above marked
tool.
Greetings,
Andreas

This was a huge help! Thank You!!
I have another dumb question. In composer is there a way to zoom to the
inverted polygon for the display?
I feel badly about all of these dumb questions!!
THANK YOU again!!

Hi Mike,
Perhaps you could use the "inverted polygon" renderer to cover/hide areas
outside your area of interest?
See
https://docs.qgis.org/testing/en/docs/user_manual/working_with_vector/vector_properties.html#inverted-polygon-renderer
or https://www.youtube.com/watch?v=MHhYDdTC2vg
By using this symbology technique you are not actually clipping the data, but
hide areas ouside a defined polygon "on-the-fly".
Hope this helps,
Andreas

I am trying to clip a basemap to a polygon and am struggling. I have tried to
follow suggestions from others about doing this but have not been able to make
it work.
What I am trying to do is use the portion of the basemap for the region in
Composer
Thank you in advance for any suggestions
