What’s the correct answer for this please ?
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.
