Two-point perspective uses two vanishing points, both on the horizon line, to draw an object from its corner — showing two receding faces at once instead of one flat front.
It's how you draw most real-world objects and buildings, since we rarely view things dead-on. It reads as far more dynamic and spatially convincing than a one-point setup.
Draw the horizon line, then place two vanishing points on it — one far to the left, one far to the right of your page.
Draw a single vertical line — this is the nearest corner of your object, closest to the viewer.
From both ends of that vertical line, lightly draw guide lines out to each vanishing point.
Add a second vertical line on each side to define how wide each of the two visible faces is.
Connect the tops and bottoms of those new verticals back toward the vanishing points to close each face.
Darken the true edges of your form and erase the extra construction lines.
Draw a simple box or building corner first before attempting anything complex — get comfortable finding both vanishing points before adding detail.
