From Fusion360

Adaptive clearing

Select bottom contour of each hole to cut
Then go to tool in the 2D adaptive side bar, and click select
Select the tool that you will use, if you don't have one select new mill tool
Create the tool you are going to use, normally flat end mill, and set the rest of the tool settings
Select OK, and then select the tool you have just created
Set the spindle speed and cutting feederate appropriately, according to the chart
Skip the height menu, go to passes
if cut is more than 1/8", use multiple passes to reduce heat.
Uncheck "stock to leave"
Go to linking, if your project will leave parts cut out without support, leave tabs to support project
Select OK, and then right click the tool path, and simulate to ensure the path is correct.

2D Contour

select bottom contour of the outside perimeter

then go to tool in the 2D contour, and click select
Select the tool that you will use, if you don't have one select "new mill tool"
Create the tool you are going to use, normally "flat end mill", and set the rest of the tool settings
Select OK, and then select the tool you have just created
Set the spindle speed and cutting feederate appropriately, according to the chart. Generally a bit slower than the Adaptive clearing, about 3/4 the speed.
if your project will leave parts cut out without support, leave tabs to support project
In the geometry tab, select Tabs

The tab should be at least the height of 2 passes, larger parts require more/larger tabs.
Skip height menu, go to passes
if cut is more than 1/8", use multiple passes to reduce heat.
Uncheck "stock to leave"
Select OK, and then right click the tool path, and simulate to ensure the path is correct.
