I started by drawing half of the glass in Illustrator. Then the drawing was imported to 3ds max. Then under the hierarchy tab I edited the pivot point. This was because the pivot point by default was in the centre of the drawing, but the pivot point needs to be on the left hand side to create a glass using the lathe tool.

Then I used the lathe tool to turn the drawing into a 3d shape that resembles a glass. Then under parameters I had to select the flip normal option. This was because by default the shape was inside out. Then finally I selected the patch option to remove any dark patches on the glass.

This is my drawing of my glass in Adobe Illustrator.

This is how the glass looked finished.
