PART A4-5: You may use only four steps to create this part. These steps must be in the following order: REFERENCE PLANE, LOFT, SHELL, and REVOLVE. Multiple reference planes ar needed, but must be created with a single feature. Assign the bottle glass materials properties (SOLIDWORKS Materals>Other Non- metals->Glass). Change the color to blue. Measure the mass of the bottle and report the value (to the nearest .1g) in the comments section when uploading the part to D2L.
