Below is problem MV1 from the course pack. In an earlier assignment, you created a multiview drawing of this part. Model this part with SolidWorks, with each grid spacing equal to one inch. Create a SolidWorks drawing of this part, with Front, Top, and Right Views. Import dimensions from the SolidWorks part file, and place them on the drawing so that they can be easily read. Add a note that all dimensions are inches. Add your personalized title block that you created in Chapter 2 to this drawing. *Important: Save the drawing first as SolidWorks Drawing (filetype *.slddrw) and then as an eDrawing (filetype *.edrw)! You will upload the eDrawing in Blackboard, not the SolidWorks Drawing - the SolidWorks drawing is associated with the part file, I cannot open the sw drawing unless you also send the part file; however, l can open the eDrawing without the part file.

explain in a paragraph pls
hand written plz Answer the following questions using the information provided in this unit. Know and Understand 1. True or False? The primary purpose of section views is to help feature exterior detail without using hidden lines. For the next three terms, match the three types of lines to the three descriptions. Answers are used only once. 2. Cutting-plane line 3. Section line 4. Short break line A. Not exclusive to section views, but needed for broken- out sections. B. Drawn thick in a view adjacent to the section view. C. Drawn thin, and usually continuous, but sometimes dashed. 5. Of the following, which is not a type of section view featured in this unit? A. Full B. Half C. Quarter D. Offset 6. True or False? The preferred dividing line between the two halves of a half-section view is the visible line. 7. An object with a number of odd features, such as spokes or holes, often has a(n) section so the odd features can be rotated around the axis into a vertical cutting plane,…
