Attached is the drawing with some measurements. in ISO SE, Suppress hidden lines. I selected the workplane by 3 points, chose the face I want to measure along. Measured along the face to the center of the bored holes, by snapping to the vertex of the part, then snapped to grid that is center of the bored hole. Will not let me snap to the center of the bored hole. This part, it works out ok. But, if the holes where not aligned with the grid, I would be in trouble. Also, if you notice, the measurements are backwards? Any suggestions or advice on better ways to do this greatly appreciated.
