Picking up where we left off in Perspective Tips 1 & 2, remember to start with a Horizon Line and point(s).
I remember learning to construct a perspective the "correct" way in school and finding it far too complicated and technical. For me, it took the enjoyment out of drawing, but luckily I learned a few tricks from my dad which are the inspiration behind Tips 3 and 4.
Correct proportions in a perspective are important, so some sort of reference element is necessary to begin. My favorite reference element to use is an existing wall section, and I have found that drawing on top of an in-scale section can save time.
Beginning with an existing section and extending the lines toward or away from your point on the Horizon Line is the basis for constructing a perspective. An in-scale section of the space can also be used as a reference element.
Other reference elements to begin with could be an existing elevation or dimension line.
Tip 4 can help with working in and out from the reference element. The trick is to look for squares in plans and elevations.
Of course there is still a fair amount of estimation involved, but with practice you will see the division of squares.
Stay tuned for the next installment of tips 5 and 6.
