help with technical drawing homework?
im awful at technical drawings, so if could answer these questions i'd be grateful.
1. why would professionals, such as machinists and contractors, prefer multiview drawings over pictorial drawings?
2. how would you describe the geometric relationship thta exists between the adjacent views of a multiview drawing?
3. why is it important to layout a multiview sketch with points and construction lines before drawing object lines?
3. what is the purpose of hidden lines and center lines?
1. Pictures lack scale and specific measurements. Further, they do not convey what's behind the picture you can see.
2. Multiple views help describe each other. Their display of visible and hidden lines convey what can and isn't seen.
3. Corresponding points and construction lines help a draftsman line-up the features so they correctly depict the object being drawn.
4. Hidden lines are part of the object and just because you can't see them on a picture doesn't mean they aren't important. Hidden lines help you visualize and understand the object from all sides. Center lines give reference positions and are especially useful in symmetric objects.
