Sofa and Chair CAD Blocks

An 84in sofa, a 58in loveseat, an accent chair, a dining chair and an office desk with chair - five seating CAD blocks that cover both the living room and the workstation. Dining chairs get placed in multiples around a table, which is why the chair is its own block rather than part of the table. Free DXF downloads.

84-inch Sofa

Residential Furniture - datum: near-left corner (back at far +Y edge) - default footprint 84in x 36in

84-inch Sofa - plan view CAD block
84-inch Sofa - plan view, 84in x 36in

Three-seat sofa for living rooms, family rooms, and lobby seating groups. It is usually the first block placed in a living-room layout, because the television wall, the rug, and every other seat orient to it.

Sizing

The 84in default is the standard three-cushion sofa length; 72-96in covers an apartment sofa up to a long great-room piece. Depth 36in default with a 32-40in range - past 36in the seat reads as lounge depth and starts eating into the walking path.

Drafting notes

The near-left corner is the datum with the back at the far +Y edge, so inserting against a wall puts the +Y face on the wall line. That is the opposite convention from wall-line blocks like the dresser, and it is the usual source of a flipped sofa.

Drawn alongside

Drawn at ninety degrees to a loveseat, facing accent chairs, with the TV console on the opposite wall.

58-inch Loveseat

Residential Furniture - datum: near-left corner (back at far +Y edge) - default footprint 58in x 34in

58-inch Loveseat - plan view CAD block
58-inch Loveseat - plan view, 58in x 34in

Two-seat sofa for smaller living rooms, apartment plans, and lobby seating where a full three-cushion sofa overwhelms the space. Frequently set at ninety degrees to a longer sofa to close a conversation group.

Sizing

Default 58in, adjustable 48-64in - the band where a piece still clearly reads as two-seat rather than a small sofa. Depth 34in default with a 30-38in range, slightly shallower than the 84in sofa's 36in default and noticeably easier to walk past.

Drafting notes

It carries the same back-at-+Y convention as the sofa, so a loveseat swaps in for a sofa at the same insertion point when a layout tightens up and the back stays on the wall without re-aligning anything.

Drawn alongside

Drawn with the sofa and accent chairs in a single seating group, closing the fourth side of the arrangement.

Accent Chair

Residential Furniture - datum: near-left corner - default footprint 26in x 26in

Accent Chair - plan view CAD block
Accent Chair - plan view, 26in x 26in

Lounge or occasional chair for living rooms, lobbies, and waiting areas. Its job on a plan is testing conversation-group geometry - whether a seat can face a sofa across a workable distance without blocking the walking path behind it.

Sizing

Default 26in square, with both axes adjustable 22-34in. That range covers a slim slipper chair up to a wide club chair or recliner body. Unlike the dining chair it is drawn at its resting footprint, since it is not repeatedly pulled in and out of a table.

Drafting notes

Near-left corner datum, and the footprint is square at default, so the block rotates to any angle in a seating group without the insertion point reading oddly against the geometry.

Drawn alongside

Drawn facing the sofa or loveseat across a conversation group, usually with a floor lamp standing at one shoulder.

Dining Chair

Residential Furniture - datum: near-left corner - default footprint 18in x 20in

Dining Chair - plan view CAD block
Dining Chair - plan view, 18in x 20in

Individual dining or side chair, used loose where the seat count differs from what the table blocks carry built in, or to show a chair pulled away at a desk or console.

Sizing

The seat plots 18in across and 20in front to back by default, with a narrow 16-22in by 18-24in adjustment band, because side chairs simply do not vary much. Roughly 24in of table edge per chair is the standard allocation, so an 18in seat leaves working elbow room between neighbors at a full table.

Drafting notes

The 18in x 20in footprint is the chair body alone, with no pull-back envelope built in - that is the difference from the dining and conference table blocks, whose bboxes already include the chair ring pulled clear. Placing chairs loose means adding that pull-back yourself before checking circulation behind them.

Drawn alongside

Added to the dining table and conference table blocks wherever the seat count is odd or a chair sits away from the table.

Office Desk with Chair

Commercial Office - datum: back-left corner of desk on wall line - default footprint 60in x 53.5in

Office Desk with Chair - plan view CAD block
Office Desk with Chair - plan view, 60in x 53.5in

Straight desk drawn with a task chair symbol, for private offices, open-plan benching, and home-office callouts. It is the quick way to show a station is occupied without committing to a full panel system.

Sizing

Default 60in x 30in, adjustable 48-72in wide and 24-36in deep. A 24in depth is the shallow limit for a monitor-plus-keyboard station; 30in and up carries dual monitors or a wet-signature work surface without crowding.

Drafting notes

The back-left corner sits on the wall line so the desk butts to a wall face. The 53.5in bbox depth is deeper than the desk because the chair swings 23.5in past the front edge - that swing is the aisle check.

Drawn alongside

Placed against the cubicle block on the same plan and paired with a file cabinet at the desk return.
