Conclusion Questions
1. What is the purpose of construction lines? Object lines? The purpose of construction lines to the guide the rest of a technical sketch. The purpose of object lines is to outline a technical sketch.
2. What is the purpose of hidden lines and center lines? The purpose of hidden lines is to show lines that can't be seen from the view at which the drawing of the object is shown. The purpose of center lines is to show the center of circles, arcs, and symmetrical parts in technical drawings.
3. What type of pictorial is shown in the first representation in item 2? How can you tell? Oblique is the type of pictorial that is shown in the first representation in item 2. I can tell this because I know that it's not isometric because it doesn't show the front, top, and side faces in one view, and I know it's not perspective because it doesn't have any slanted lines, and I know that it's not multiview because it doesn't show the view of one side of the object. Therefore, since it's none of the other types of pictorial sketches it has to be an oblique pictorial sketch.
4. What type of pictorial view is shown in item 6? How can you tell? Isometric is the type of pictorial that is shown in item 6. I can tell this because it shows the front, top, and side face of the object in one view and the sides meet at a point making them 120 degrees which are the requirements of an isometric sketch therefore making item 6 an isometric pictorial view.
5. Why would building professionals, such as machinists and contractors, prefer multiview drawings over pictorial drawings? Building professionals would prefer multi-view drawings over pictorial drawings because multi-view drawings show the front view, top view, and side view of an object which adds more detail to the overall drawing and helps to fully interpret what you were trying to create with your multi-view drawings which is more detailed than drawing the same thing but as a pictorial drawing.
