Internal corners in cutting operations in CAM space

[JYZMT]

A CNC can't do sharp interior corners. There are techniques and even a great add-in by the fantastic @prainsberry to add dogbones in the model space. But these can add complexity, and can bug out when changes are made to some parameters or operations suppressed.

There are also some interesting "sharp corners" options for 2d Contour Cam operations (Although not a lot of guidance on this)

There have also been requests for dog bones options before on the ideas station.

I'd like to reiterate this request, but concentrate in the CAM space, keeping the models simpler and where it really does not seem that far away from the current tools? 

Can we have a "remove sharp corners tick box" in the cutting 2D profile operation? This could just add an over cam to a internal corner to allow square objects to be inserted (often raised in the forums)? I've attached a sketch. I've avoided arcs in the corners, because in my experience some CNC machines slow right down for arcs and can catch fire - but the key here is with the overshoot relief, a square cut sharped cornered item can be inserted into the cut/pocket.

This might be something you want to check:

I absolutely support the notion of having a checkbox option to remove sharp internal corners in CAM.

However, AD has been sitting on this for a very long time and seem reluctant to move on it.  While dogbones in the model are not the most ideal, the add-in initially created by caseyrogers and patrickrainsberry was a good stop gap.  Just so you know - @DVE2000 and I have taken over ownership of the add-in, and we've just released version 2 - it addresses many of the issues of the old version, and adds options to create normal, minimal and mortise dogbones, as well as dogbones cut from the topface and selected face.  Both static and parametric dogbones are options too.  We've tried hard to make the add-in easy to use, including deleting the dogbones, if all goes awry.

You can find it here, if you are interested.
