I did your mom.... a favor by making you.... a sandwich:))
Just because they cross over each other doesn't mean they aren't still called lines.
couple of reasons.... if you are drawing and dimensioning with a computer program the dimension will be inaccurate... If it is mechanical drawing then the fabricator would not have enough information to accurately measure the component. ie a circle turned a few degrees away from perp. would appear to be an ellipse. and may actually dimension that way
rise over run. That would be a 4" rise for every 12" run. In other words, 4" vertically over 12" horizontally
In the Son of Anarchy they turn a picture over when someone is out, killed, or will be gotten rid of.
18" o.a.
boring
For putting to many dimension on top of the dimension!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Tabular dimensioning
Dimensioning standards are standards on how to dimension a working drawing.
Baseline dimensioning is a method of dimensioning in technical drawings where all dimensions are referenced from a single baseline, reducing the chance of errors due to accumulation of tolerances. It helps to maintain clarity and consistency in the layout of dimensions on a drawing.
It show dimension of given dig. Ex. length meter etc. > chain dimensioning as opposed to datum dimensioning. chain dimensioning: 4 holes in line on a drawing, first hole position dimensioned from the edge, remainder dimensioned from the centre of the previous hole. datum dimensioning: all holes dimensioned from the edge. the cumulative tolerance build up on the chain dimensioning allows for greater overall tolerance build up.

What is the difference between the conventional method of dimensioning and the baseline method of dimension
they are used by showing where it is
You are putting too many dimensions on it. For example, if there is a L shaped sketch and you dimension from the bottom of the L to just above the horizontal part, and then you dimension the vertical part from the end point of the last dimension you'd be okay. But, if you dimensioned both of those lengths and then the total length you would be over dimensioning the sketch.
