Line + Mass

Envelope, masses, detail

Enclose the subject in five straight lines. Divide that into big masses. Add detail last, and least. Spend half your time on stage one.

Every drawing in this course is built in the same three stages. First the envelope: a simple polygon of five or six straight lines that just encloses the whole subject, sighted and measured so its proportions are right. Second the big masses: the envelope divided into the main shapes (the tower, the nave, the roof, the tree, the ground), still as straight lines and simple curves. Third the detail: windows, mouldings, foliage texture, and only as much as the design needs.

Beginners start at stage three, drawing a window beautifully in a wall that is the wrong size on a building that is in the wrong place. Masters start at stage one, and if the envelope is right nothing after it can go badly wrong. Spend half your drawing time on the envelope and the masses. It will feel slow. It is the fast way.

Draw the envelope with a 2H, lightly, so it can be adjusted and later erased. Check it with plumb, level and comparative measurement before moving on. The moment you move to stage two, the envelope becomes law.

Pitfalls

What

Starting with the most interesting part.

Why

It will be beautifully drawn and wrongly placed.

Fix

Start with the dullest part: the outer edges of the whole subject.
