It's all perspective based. You may not be specifically plotting a 3d cube on an xyz axis, but every object has a basic simplified bounding box which can be placed in perspective (sides, front, top/bottom). Placing planes in space requires this basic understanding, be it intuitively done to look "correct", or meticulously mapped out with grids and so on.
There is obvious benefit to learning perspective with exercises of course and plotting out perspective and drawing in a very technical way, especially at first, but then it is good to attempt to intuitively paint or draw with a basic perspective in mind. I find, for landscapes especially, setting a basic perspective grid first (2, 3pt etc) is always helpful to allow you to keep in mind and potentially use to troubleshoot things when the intuitive placement isn't working. If you are reverse engineering a perspective view to add another object, map out the grid of the scene, then add your object using it's basic bounding box. It can get much more complex if you want to learn how to exactly map objects. Scott Robertson has a book called How to Draw that delves into all the technical aspects, but it is dry and overly technical in many ways especially as it advances, if you aren't doing specific industrial design type work.

Many people swear by using 3d programs to visualise basic planes and objects, as you can move the camera around and is actually quite a good thing to do, simply to learn, if you are less on the side of being able to intuitively visualise things in a 3d space. Practice drawing things from reference in many perspectives to build up your intuitive understanding. Draw from life, as well. It will all come down to practicing what you want to be able to do.
