Block-in process
Laying in a clear, simple shape version of your subject before details, so proportion and placement are solid from the start.
What it is
Block-in is the stage where you reduce what you see to big, simple shapes and lines. Instead of drawing eyes, fingers, or buttons, you enclose the subject in a simple outer shape, then break that shape into a few clear pieces. You're building the scaffold the rest of the drawing will hang on.
In practice this starts with an envelope: an outer shape that catches the furthest top, bottom, left, and right points, plus any major angles. From there, you carve the envelope into large blocks: head, torso, and other major masses, adjusting until the silhouette and tilt feel right.
As you refine the block-in, you use landmarks and shape comparisons to keep it honest. Landmarks are recurring, easy-to-spot points you can aim for (corners, joints, sharp bends). You compare positive shapes (the object itself) and negative shapes (the gaps around it) against your reference, nudging lines until the big shapes lock in. The result is a flat, graphic map of the subject's main structure before any rendering or detail.
Why it matters
Without a solid block-in, everything you add later is guesswork: details land in the wrong place, forms drift, and likeness suffers no matter how carefully you shade. A reliable block-in process catches errors while they're still cheap to fix, and separates finding the drawing from finishing it.
You can check it when
- ✓You can stop at the block-in stage and it already reads clearly as the subject, even with no shading or detail.
- ✓Your initial envelope and big shapes change less and less as you continue; you're making small corrections, not constant major redraws.
- ✓You can look at your block-in and point to clear, simple shapes (both the subject and the gaps around it) rather than a web of scratchy search lines.
- ✓When you compare your block-in to the reference, the silhouette, tilt, and major masses match before you touch any fine features.
