This is quite embarrassing, well perhaps it isn't, but I've made it through 2 years of engineering without learning how to effectively draw in 3D. The need for this skill arises from the fact that in my Applied Math course we are computing Flux and other such integrals that require knowledge of the surface in 3D space. We didn't really have to use this skill after highschool until now.
Typically what I've done is set x,y,z = 0 accordingly and graph in the appropriate planes. However, this doesn't work all that well. Sometimes I get a shape that's completely off the mark. Are there any tips on graphing in 3D?
We do not get calculators so major plugging and chugging isn't really an option (too slow on an exam anyways).
