There's tools such as onlineflightplanner and simbrief which work out waypoints between destination and arrival airports. 

These two don't work out your SID then STAR. So I'm left going to something like ChartFox to figure out my STAR then Approach. It's okay but not every airport is there and it's realy headache to switch between all the charts to find what I need. 

Is there a free tool out there that can help with this?

Hi There.

In the U.K. try this     http://www.nats-uk.ead-it.com/public/index.php.html

In Europe try this     https://www.ead.eurocontrol.int/cms-eadbasic/opencms/en/login/ead-basic/    Free registration required.

Elsewhere try this    https://skyvector.com/

I hope this helps you.

Try LittleNavMap.

It will read all the scenery files to build it's nav database, and will also use Navigraph ARIAC if you have that. Its a little tricky to learn, but you can use it to visualize all of the SIDS and STARS. You can even use it to build a flight plan and export it to the .pln format to load in MSFS.

Avliasoft EFB has all the sids and stars that are in MSFS 2020. https://www.aivlasoft.com/
