Free wall-mounted cooker hood CAD block

A wall-mounted hood is the chimney-style extractor that fixes to the wall above a hob, with a canopy capturing the cooking fumes and a flue rising to the ceiling. This page gives you a free wall-mounted hood CAD block drawn in elevation, so you can hang it over the cooker on the cooking-wall drawing, set its height above the hob, and run the flue up to the soffit. It downloads in DWG for AutoCAD 2004 and later, free for personal and commercial use, no signup, no watermark.
The wall hood is primarily an elevation element: its whole job is to read on the cooking wall, sitting centred over the hob with the canopy and flue drawn at their real proportions. Placing it well is partly ventilation — capturing the plume from the burners — and partly composition, since a chimney hood is a focal point of the kitchen wall.
Use it on kitchen joinery and presentation elevations, paired with the hob below and the cabinet runs either side. For the plan-and-services side of the extract, reach for an exhaust-fan or plan-view hood block instead.
What the wall-mounted hood block shows
Drawn face-on, the block shows the hood as it appears on the wall: a canopy — flat, angled, or box-shaped depending on the style — sitting over the hob, with a flue or chimney section rising from the canopy up toward the ceiling. That silhouette is what reads on the elevation and what gives the cooking wall its vertical accent above the worktop.
The block is a single reference you move, copy and mirror as one object. On its own appliance or services layer, separate from the cabinetry, it lets you produce a clean cabinet elevation or a fully-fitted one from the same drawing. Because the flue is part of the same block, you can stretch or trim it to meet whatever ceiling height the room actually has.
Hood width and mounting height above the hob
Two dimensions govern a wall hood. The canopy width should at least match the hob below it — a 600 mm hood over a 600 mm hob, a 900 mm hood over a wide range — so the canopy captures the plume rising off the back burners rather than missing it. A hood narrower than the hob is a common drawing error that the scaled block makes easy to avoid.
The second dimension is the clearance between the hood and the hob. Manufacturers specify a minimum mounting height above the cooktop, and it differs for gas and electric hobs, so rather than fix a number, set the hood at the manufacturer's recommended clearance for the hob type and confirm it on the elevation. The flue then runs from the top of the canopy to the ceiling, its length set by the room height.
Hanging the hood on the elevation
Insert the block full size in millimetres — scale 1 in a millimetre drawing, or set INSUNITS to millimetres so AutoCAD rescales on insertion. Centre the canopy horizontally over the hob so the extract sits over the burners, then set its vertical position at the recommended clearance above the cooktop.
With the canopy placed, extend the flue up to meet the ceiling line; if the room is tall, the flue lengthens, and most chimney hoods have a telescopic flue that the block can represent by stretching. Mirror the block if the kitchen layout flips. Because it is a block reference, you can copy the hood to test it against the wall composition before committing the joinery around it.
Wall-mounted vs island vs integrated hoods
Knowing the hood type tells you which block to reach for. A wall-mounted (chimney) hood fixes to the wall above a hob and flues up the wall to the ceiling — the block on this page. An island hood hangs from the ceiling over a hob in an island, with no wall behind it, so its flue drops from the soffit. An integrated or canopy hood hides inside a wall cabinet or behind a fascia, so it barely reads on the elevation at all.
For a hob set against a wall, the wall-mounted hood is the natural choice and the one that gives the elevation its chimney feature. If your hob sits in an island, you want an island-hood block instead, hung from the ceiling rather than fixed to a wall.
Who uses the wall hood block
Kitchen and interior designers use it to compose the cooking wall and confirm the hood sits at the right height and width over the hob. Architects use it to populate residential kitchen elevations with a scaled, believable extractor. Joiners and fitters read the elevation to set the hood and flue against the ceiling. Students use it for studio kitchen drawings where licence-clear appliances matter.
It pairs with the hob or cooker block directly below it, the wall-cabinet runs either side, and the exhaust-fan block on the services layer that carries the ductwork behind the visible canopy.
Coordinating the hood with the duct and the cabinets
The visible hood and the ductwork behind it have to agree. The flue you draw up the elevation usually conceals a duct rising to a ceiling or external termination, so coordinate the hood's elevation position with the exhaust-fan and duct route on the services plan — they should describe the same extract path. Keeping the hood on its own layer lets you align the two without one drawing's geometry cluttering the other.
Watch the cabinets either side: a chimney hood breaks the wall-cabinet run, so the units stop short of the hood and the flue rises in the gap above. Drawing the hood to scale shows exactly how much of the wall-cabinet line it interrupts, which is the kind of thing the joinery drawing has to get right before the cabinets are made.

Questions
Frequently asked
How wide should the wall-mounted hood be?+
At least as wide as the hob below it — a 600 mm hood over a 600 mm hob, a 900 mm hood over a wide range — so the canopy captures the plume from the back burners. A hood narrower than the hob is a common error the scaled block helps you avoid.
How high above the hob does the hood go?+
Set it at the manufacturer's recommended minimum clearance above the cooktop, which differs for gas and electric hobs. Rather than fix a single figure, draw the hood at the specified clearance for your hob type and confirm it on the elevation.
What's the difference between a wall hood and an island hood?+
A wall-mounted (chimney) hood fixes to the wall above a hob and flues up the wall; an island hood hangs from the ceiling over a hob in an island, with its flue dropping from the soffit. Use the wall hood for a hob set against a wall.
Is the wall-mounted hood block free for commercial use?+
Yes. It downloads free in DWG with no signup, no watermark and no attribution requirement, and it is cleared for commercial project use.
