Print Dimensioning - 2 Flashcards
What is the first view you should choose when creating a multi view drawing?
The front view, because it is the most detailed side.
What should you do if the front view is not the most revealing?
Change the front view to any side with the most information.
If the front view is not obvious, what side should you chose?
Select the view you think is best.
What other views are needed when you have selected the front view? Explain why.
The Top or Right views because the front view only shows width and height. Not the depth.
After selecting the view that shows depth, what view should you choose next?
The view that shows the most features that the front view doesn’t show.
Lets say we have an L-Shaped Bracket, and we have the front and top view show all principal dimensions, do we need to show another view? and why?
Yes because the “L” view was not shown on either view which shows more information.
What type of viewed drawing is commonly used to make a print of an object less complex like a six-view drawing does.
A Three-View Drawing
Lets say you have a rod, how many views would you need?
Only two.
Some objects only need one-view like rings, what else shows information besides views?
A note.
What are two-view drawings for?
They are used for objects that require to show more detail like symmetrical cylindrical objects.
What is the function of a dimension on a print?
The function is of dimensions is to specify the size and location of features on an object.
What are the three dimensions?
Height, Width, Depth.
What do dimensions also indicate on a print dimension?
Radii and Diameter of rounded features.
What are four features used indicate dimensions?
Extension lines, Dimension Lines, Dimension Units, and Leader lines
What are Extension lines?
Extensions are the points used to create the dimension.
What should you do when drawing Extension lines?
They should be drawn as thin solid lines extending from the edges of the object lines.
What should an Extension line have so it isn’t mistaken to be an object line?
A small gap.
If an Extension line crosses an object line, do you break the line to create another small gap?
The line should not break if there is an object line in its path.
What are Dimension lines?
Dimension lines are an indication to the extension lines that define the dimension.
What shape is used to determine a Dimension line? What do they indicate?
An Arrowhead. They point towards the extension lines.
What if the extension lines are too small of a space? Where do you place the Dimension lines?
On the outside of the extension lines pointing inwards.
What are Dimension Units?
Dimension units specify the measured value of an object feature. Given by a number and a unit of measure. (Ex. inches)
To avoid abbreviations in dimension units, where should you place your unit of measure?
You should put a note in the title block of the drawing saying: UNLESS OTHERWISE SPECIFIED, ALL DIMENSIONS ARE [INCHES, MILLIMETERS, ETC.].
What is a Leader?
A leader attaches a note or a dimension to an object.
