What is the difference between proportion and scale? What tools are useful for drawing straight lines? What tools are used for drawing arcs and circles?

1. You are considering modifying a model by changing dimensions in a drawing view. What problems might you encounter when using a constraint-based modeler without bidirectional associativity? What problems might you anticipate when using a constraint-based modeler with bidirectional associativity in this task? 2. Sketch the symbol for third-angle projection. 3. List the six principal

Sketch the top, front, and right-side views of an object of your design having normal, inclined, and oblique surfaces. In a drawing that shows the top, front, and right-side view, which two views show depth? Which view shows depth vertically on the sheet? Which view shows depth horizontally on the drawing sheet? What is the

1. What dimensions are the same between the top and front view: width, height, or depth? Between the front and right-side view? Between the top and right-side view? 2. List two ways of transferring depth between the top and right-side views.  3. If surface A contains corners 1, 2, 3, 4, and surface B contains

If a plane surface intersects a contoured surface, should you show a line in the drawing to represent that intersec – tion? What about when the plane is tangent? What is a fillet? A round? A lug? A boss? Knurling? How do you show right-hand and left-hand parts? Which is easier, creating an enlarged detail
