1. RTFM on chamfered edges.
2. Learn to read the drawing. It tells you there is a 10 unit radius (centered on the 8 unit diameter hole) that forms the edge· Drawing the 10 unit radius circle will give the intersections for the chamfers.
3. Practice basic geometry. The radius, i.e. the depth from the top edge to scribe the two curves either side of the central (face on section) can be calculated knowing the chord, and that the centre lies half way between - the program will draw the arc for you when given the points anyway.
4. Use Solid Edge - as was used to create the image you included.
5. Your original question is ill defined.
