Six View Orthographic Drawing With Fillets and Rounds Angry

Greetings,

This is my first semester in a drafting and design (CADD) program and my instuctor isn't the best at explaining things.  I am trying to draw a six view orthographic drawing of a dovetail bracket made of cast iron that has fillets and rounds that are 1/8R.

While I understand what fillets and rounds are, I am completely confused on the visabilty "rules" for drawing them on paper in a orthographic drawing.  Does anyone out there understand the theory behind this???  My instructor loves to mark my drawings wrong, but doesn't seem to want to explain how I can stop making these mistakes.

For example, I have a isometric pictorial sketch of this dovetail bracket that I need to draw with partial dimensions.  From this drawing, I can clearly see that I need to have a couple of rounds on the front view of my orthographic drawing, but when I go to draw the left and right-side views, I am totally lost on whether or not I should draw or not draw the line with the round???

I am so tired of getting marked off for this stuff.  I have searched the Internet and visited B&N and BooksAMillion to find another drafting/engineering drawing textbook to see if I could find the answer but wasn't able to find anything other than the standard definition of fillets and rounds.

Can somebody please help???

Thanks!

Derrick

Derrick,

My favorite drafting instructor would say that "the first rule in drafting is that there are no rules in drafting as long as the parts get built to the designers intentions."
As a person whom has checked may production drawings, I would say that it really doesn't matter as long as all the views are the same. Nothing can become more confusing to fabricators than trying to compare visualation methods between views on a single drawing.

Best of luck,

Bo

Derrick,

Are you referring to what the fillet and round look like in the iso view, and whether or not to show the lines that represent those features?
