Hello, could some engineer or expert in your field help me with the drawing. 1) How do I display rounded edges in a projection? Should I display them only by an imaginary line? 2) How do I dimension rounded edges? According to the textbook, I have to take the intended intersections and dimension them at the meeting point. 3) The body I received in the drawing has the same holes in the section. I can dimension holes, but there are a total of three. Two visible and one invisible - (it is not dimensioned in the section, is it?). How will they be listed? I have to dimension each or only one. And what about the third one? 4) In the lower part of the body, a part of the circle is "cut out" into the body. Can I roll her in a cut? When is half? Bottom view is not allowed. Can I turn the body 180 degrees? Input - http://goo.gl/YjyqPI (Page 15) Must have Adobe reader 9+ and saved on disk. If you would be willing, feel free to mark the kitten in painting and write, for example, RX, etc ... In the case, please send clippings to [email protected] I apologize for any grammatical errors . Thank you all for your help!
