<p>If you guys don’t mind, please look at this drawing and tell me any mistakes (in regards to dimensioning) that you see. This is only a rough sketch, so lines may not be straight. Sorry if its messy and unclear, but it’s the best I can make it on my cheap computer. Thanks. Just post errors/mistakes in this forum.</p>

<p>NOTE: Other than the non-straight lines, all dimensioning marks are made ON PURPOSE.</p>

<p>The only thing I can say is that I was taught that all the dimensions should preferably be on drawing that shows the feature in its true form. for ex. the 1/2 inch height on the right side view should be on the front view. i don’t think that should matter but my teacher was really picky.
Also you need 2 - 5/8" dimensions on the top view.</p>

<p>Just looking quick at this, your top view is not drawn correctly. Look carefully at your isometric view, then at the angular projection in the top view. It projects the wrong way. You also need to specify the height of the angular projection, and “R” in the front view is not correct, should be an angle symbol. “R” is for a radius callout.</p>

<p>Do you mean I need to specify the height from the bottom edge to the vertex? How would I calculate the height?</p>

<p>You should post this kind of stuff on <a href=“http://www.physicsforums.com%5B/url%5D”>www.physicsforums.com</a>. Doesn’t your textbook outline some basic rules on dimensioning or I guess there isn’t one, I’ve seen a few graphics courses that did not have a textbook required.</p>

<p>I don’t have a textbook, and I can’t remember some of the basic rules that my professor taught. However, I did create a different thread asking for book recommendations.</p>
