Three-seat sofa with slim arms and projecting seat
Free CAD block from the Sofas library (193 blocks), drawn 1:1.
About this block
Three-seat sofa with slim arms and projecting seat, drawn in plan, front and side elevation, the elevations drawn to match the plan. It measures 6' 7" wide, 2' 2" deep and 2' 7" high (2.00 m × 65 cm × 80 cm), and it is drawn 1:1, full size, so it drops into any drawing set up in meters or in inches without rescaling.
It also comes as a 3D model built from these drawings.
From the Sofas library: 193 blocks drawn to one standard, each one available on its own.
In practice
Where it goes
Contemporary open-plan apartments, co-working floors and showrooms use this 6 ft 7 in (2 m) three-seater as the main piece of a seating group. On the plan it often floats with its back to the dining zone; the projecting seat shows as a line ahead of the slim arms, so orient the block with that edge toward the table and the arms toward the circulation.
Clearances to leave
Two meters (6 ft 7 in) on the nose, so it aligns with an opened sofa bed or a window bay in the same room. Leave 16–18 in (40–45 cm) from the projecting seat edge to the table, and 36 in (90 cm) behind the back if it floats; the 26 in (65 cm) depth keeps the group under 6 ft 7 in (2 m) deep.
Pairs with
The Two-seat sofa with slim arms and projecting seat sits at right angles to it and the Slim-arm armchair with lumbar pillow closes the group. For a longer wall use the Four-seat sofa with slim arms and corner cushions; a wood plinth suits the frame.

Design notes
- Coffee table 15½" to 19½" from the sofa: close enough to reach a cup, far enough for your knees.
- Keep main walkways 3' 0" wide; 2' 6" is the tightest comfortable passage.
- For a 65-inch screen, sit about 6' 7" to 11' 2" away, measured from the seated head.
- Armchairs facing each other across the table make a conversation area; keep the seats within about 9' 10" of each other.
