Blob tool and profile tool combined as 1 tool.

I would like to click and drag a box (like how the blob tool works) over an area of a part. But for whatever features are found in the box I made, I want it to trace the features like a profile tool to give it a point cloud. Then you can export features as a DXF.

If you are online programming, lets just say this part has 6 thru holes. There is no pattern to the thru holes. I would just like to drag a box over the 6 thru holes where it will trace like a profile so I can export that as a DXF.  This tool also will allow you to click and drag over any odd shaped parts.

The profile tool only traces 1 feature at a time, I want to be able to trace as many features in the camera view at 1 time.
