How to plot 3D figures correctly? When we always draw e.g. cylinder on the whiteboard, we get kind of this: ![]( But naturally (assumed axes are perpendicular) when we have z-axis to the top and y-axis to the right, x-axis must point to us (from display) like this: ![]( And when we look from another point so that x-axis is diagonally and z-axis to the top, then y-axis naturally can't be horizontal as on first image, it is a bit rotated. My lecturer said these are two different kinds of plotting, but could not remember how are they called. So here comes the question: what are the names of both these methods (natural and alternative plotting) and how to plot correctly in both situations?

Isometric, Trimetric and Dimetric, these are all standard projections that are used for industrial purposes. ZulfiqarIII's link has all the info.
