Week 4: Multiview Drawings – 2 Here’s what we talked about last time Let’s now take another look at multiview drawings in more detail

Paster, Zorba, Medical Editor has reference to this Academic Journal, PHwiki organized this Journal TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings – 2 TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Here’s what we talked about last time TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Here we can see all the principle views of an object as the glass box is unfolded. It is easy to see that some of the principle views have more detail through the use of object (visible) lines than others. Always choose views that have the least amount of hidden lines in them in addition to show the most detail.

TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Surfaces will appear as edges at times. Edges may be as long as eshortened (shorter than normal), or “True Length” (TL). TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Oblique edge lines are created by oblique surfaces. These are surfaces that are neither true shape or true size in any principle view. TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Holes in addition to cylinders may appear “True Shape in addition to Size” (TSS), or as long as eshortened depending on the view in which they appear. (Foreshortened circles will appear as ellipses.)

TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Let’s now take another look at multiview drawings in more detail TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 We place hidden lines in a drawing to do the following things: Show hidden features 2. Clarify the position in addition to shape of features 3. Make the “plate” more readable (NOTE: The term “plate” refers to a finished drawing.) TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Depending on the application, hidden lines will either touch other hidden lines, or pass over them Note how hidden lines follow specific rules as to how they are to be laid out.

TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Center lines are used to show the theoretically perfect center of holes, arcs, cylinders in addition to bolt circles. A “bolt circle” is used to position holes or cylinders in a circular pattern. TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Center lines extend past the objects they are used to describe. TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Center lines will break their normal shape of a long dash interrupted by a short dash if an object or hidden line needs to take precedence. In these examples, only a short dash is used to show the center line.

TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 When only a short dash is used to represent a center line, there must be some space shown between the object in addition to the short dash. TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Machined Holes: Here, we can see many examples of the different styles of holes that are used in manufacturing. Each has a specific layout when it comes to displaying them with hidden lines. TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Rounds in addition to Fillets are used to relieve stress in addition to finish edges on manufactured goods.

TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 “Runouts” are used to show the topology of cast parts. TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 More examples of runouts. TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 “Intersections” are used to show the union of two or more cylinders. Several types of examples are shown here.

TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Intersections between cylinders in addition to prisms. TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Partial views are often used to simply symmetrical objects. or to TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 focus on only part of the object.

TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 “Revolved” views are used to give a clearer representation of an object. We actually “draw the object incorrectly to make it easier to underst in addition to ”. Here, webs have revolved to 12, 3 in addition to 6 o’clock positions to make the view easier to visualize. TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Here, the correct view of the object will appear to be a mass of hidden lines in the right side view. By representing only the 12 & 6 o’clock positions, we create a view that is easier to underst in addition to . Further notes would be added to the front view during dimensioning. TECH 104 – Technical Graphics Communication Week 4: Multiview Drawings 2 Arms in addition to spokes are often revolved to create a view of the object that is easier as long as the human brain to visualize.
