Free arc floor lamp CAD block in DWG and DXF

An arc floor lamp is the sculptural standing lamp whose stem sweeps up from a heavy base and curves out so the shade hangs over a seating area — the classic example being the Arco-style lamp that brings overhead light to a sofa or dining table without a ceiling fixing. This page offers a free arc floor lamp CAD block in DWG and DXF, drawn at true millimetre size so the reach of the arc and the position of the shade read correctly in elevation. It is free for commercial use with no signup or watermark.
The whole point of an arc lamp is the overhang: the base sits to one side while the shade floats above a coffee table or the centre of a sofa. That reach is exactly what you need to show on a drawing, because it determines where the base lands and whether the shade clears heads and furniture. The block captures the curve, the counterweighted base and the downward shade so the lamp's distinctive geometry is right on the page.
Why the arc changes how you draw it
A straight floor lamp stands directly over its base, so its plan footprint and its elevation align. An arc lamp does not — the shade can hang anywhere from several hundred millimetres to over a metre away from the base, so the base position and the lit position are two different points on your drawing. Showing the arc in elevation lets the designer place the base clear of circulation while the light still falls where it is wanted, over a table or seat.
The block carries the full sweep of the stem, the weighted base disc and the pendant-style shade at the end of the arc. It is drawn as clean geometry on separate layers so you can keep the base, the curved stem and the shade distinct, which helps when you are checking the overhang against the furniture below.
Reach, height and base to design around
Treat these as ranges and confirm against the specific product. An arc floor lamp commonly stands in the 1800–2400 mm overall height band so the shade clears seated heads, with the horizontal reach of the arc often in the 1000–2000 mm range depending on the design. The base is deliberately heavy and compact to counter the overhang, frequently a disc or block in the 250–400 mm footprint range.
These figures matter because the lamp only works if the shade lands over the right spot and the base does not stick into a walkway. Because the block is full size, you can dimension both the overall height and the horizontal reach straight off the elevation to confirm the lamp suits the room.
How to insert and aim the arc
The DWG is drawn in millimetres. Insert at scale 1 in a millimetre drawing, 0.001 in a metre drawing, or set INSUNITS to millimetres for an imperial template. Use INSERT or drag from a palette and pick the insertion point at the centre of the base so the lamp pivots about a sensible point.
Place the base where the floor space allows, then rotate the block so the arc reaches over the sofa or table you want lit — because the shade is offset, rotation aims the light. If the room layout calls for the arc to sweep the other way, MIRROR the block. Snap the base to the finished floor line and keep the lamp on its own lighting layer so it can be shown or hidden independently.
Where arc floor lamps are used
Arc lamps are a statement piece, so they turn up where a room wants drama as well as light: living-room seating groups, reading nooks beside a sofa, hotel suites and lobbies, lounge bars, showrooms and mid-century-styled interiors. They are also a neat solution over a dining table in a room where you cannot or do not want to fix a pendant to the ceiling.
In a presentation elevation the arc lamp instantly communicates a designed, considered lighting scheme. The same block drops into a section through a double-height lounge to show the light reaching down into the seating, and into furniture-and-finishes boards alongside the sofa and rug it is paired with.
Pairing the arc lamp with its furniture
Because an arc lamp is designed around the furniture it overhangs, it reads best when you draw it together with that furniture. Insert the sofa or dining table first, then place the arc lamp so the shade sits over the intended spot — the block makes that alignment a snap rather than a guess. Pair it with the floor lamp, pendant and ceiling lamp blocks in the lighting category for a full lighting layer.
Keep the arc lamp on the lighting layer with its own colour so you can freeze it for a clean furniture elevation and thaw it to present the scheme. When a lounge vignette is finalised, WBLOCK the seating group plus its arc lamp as a single reusable unit you can reuse across similar rooms.
Checking the overhang against heads and sightlines
Because the arc lamp's shade hangs out over a seating area, the one check the drawing must support is head and sightline clearance under the shade. Over a sofa the bottom of the shade has to sit high enough that someone standing up does not knock it, yet low enough to light the seat — a balance you can only judge with the lamp drawn full size against a seated and a standing figure in the elevation.
Over a dining table the same logic applies but with the table top as the datum: the shade lands a comfortable distance above the surface so it lights the table without blocking the view across it. Drawing the arc to scale and dropping a standing-height reference into the elevation makes those clearances a visual check rather than a guess. If the overhang fouls a sightline or a head, you see it on the drawing and can shift the base or choose a different lamp before anyone trips over the problem on site.

Questions
Frequently asked
What is an arc floor lamp?+
A standing lamp whose stem curves up and out from a heavy base so the shade hangs over a seating area, like the classic Arco lamp. It brings overhead light to a sofa or table without a ceiling fixing.
How far does an arc lamp reach?+
The horizontal reach of the arc commonly falls in the 1000–2000 mm range depending on the design, with overall height around 1800–2400 mm. The block is full size, so you can dimension the exact reach off the elevation.
How do I aim the light over a table?+
Because the shade is offset from the base, rotating the block aims the overhang. Place the base where the floor allows, then rotate (or mirror) so the shade sits over the sofa or table you want lit.
Will the DWG open in free CAD software?+
Yes. It targets AutoCAD 2004 and later and opens in AutoCAD, AutoCAD LT, BricsCAD, DraftSight and free DWG viewers including Autodesk's online viewer.
