Cutting out 1” thick wood using 1/8 or 1/4 end mill. It was suggested to widen cut which means do a pocket, how are tabs made on a pocket?

As noted at:

We added a new tab command to add tabs to a vector. If you copy the vector, you copy the tabs too. This should be helpful for users that are doing production work where they may want to fine-tune the machining of a single item and then copy and paste an array of them for full production.
Look for the new command here:
Yes I contour cut out single width. When cutting thru thick wood to minimize noise and heat I thought it was suggested to widen cutout. Is there a way to cut wider using contour and using tabs.

No, you have to add geometry, see:
While cutting up vacuum extension wands for this is expedient, it’s a bit problematic given that Shop Vac recently filed for bankruptcy, was bought at the last minute, and production hasn’t caught up.
I need a receptacle for the Sweepy 2.0 dust fitting — one option would be to purchase one from Woodcraft, but Carbide 3D sells blocks of HDPE:
which looks to be just barely big enough for things to fit.
Measuring the hose fitting I get a diameter of ~63.5mm — offsetting that twice we arrive at…
and/or
One technique which is often suggested to avoid slotting is to add geometry around a part which one wishes to cut out and cut as a pocket down to tab depth — here’s one technique for that.
In this case, the project is a bevel gauge which will be cut out of 0.0625" (~1.5mm) thick aluminum:
[bevelgauge]
Due to the narrowness of the angles, an 0.03125" endmill has to be used, so after importing and scaling the file (we will be cutting out one which is 3") we select the perimeter and offset it tw…
and consider leaving a roughing clearance and taking a finishing pass.
One which has a cutting flute length equal to or greater than the thickness of the stock — pretty much any tool should work.
Big thing is the toolpaths — if cutting out, rather than just cutting a slot:

Offset to the outside by endmill diameter plus 10% or so:

Then cut as a pocket:

down to tab height or the penultimate pass:

then move the contour down to below the pocket and start cutting at the bottom of the pocket:
