I have not explored the PSTricks' pst-solides3d, TikZ's equivalent packages, Asymptote as a tool, etc, yet.
I have a task to make some simple 3D diagrams that are related to 3D geometry subject we learnt in senior high school. For example, we need to find the cross section of a cube cut by any plane, or a point at which a line penetrate a plane, etc.
Which packages or tools do you recommend?

You mention that you've been tasked with drawing simple 3D structures. For that, a visually intuitive tool is Google Sketchup. 3D geometry for cubes is obtained by extruding (using the Push/Pull tool) a square, and model components can be intersected with one another.
Geometric perspective to the desired viewpoint is easily achieved via the orbiting tool. Print to PDF provides a means to include the resulting 3D structure to be included into your LaTeX document:
More complex figures and intersections are also possible using basic constructions of rectangles/circles and extrusions in 3D. Here the two pieces from the intersected cube has been separated:
