Please bear with me, I'm a complete noob here. My questions have to do with using Bobcadcam to draw a representation of the part want to make. I understand that I only need to draw half the profile of the part. My first question is: should I draw above or below the Z axis line? The video professor says to draw the half above the Z axis line but then my cutting tools don't make sense as they face opposite of what would be used with a lathe that uses tools coming down from the top. I better just start with that. Thanks in advance.
