Free Roman shutter window CAD block in DWG
By Sumana Kumar · Published 24 Jan 2022 · Updated 27 Apr 2024
A Roman window is the arched-head window of classical and Mediterranean architecture: a rectangular opening topped by a semicircular or segmental arch, with shutters below that open for ventilation. It carries a distinctive, formal character that a plain rectangular window cannot, which is why it recurs on traditional, heritage and resort elevations. Drawing the arch and the shutters cleanly every time is fiddly, so a ready-made Roman shutter window CAD block is genuinely useful, and this page offers one free in DWG.
The block is drawn to a believable module in plan and elevation, with the arched head, the shutter leaves and the openable indication, so it reads correctly when scaled into a real elevation. Use it on traditional house and villa elevations, heritage and conservation drawings and window schedules, and crosslink to the windows category for sliding and openable Roman variants and rectangular windows. It is free for personal and commercial use, with no signup or watermark.
What a Roman shutter window block shows
A Roman window combines a rectangular lower opening with an arched head above it, and a shutter window adds hinged leaves that swing open for ventilation. In elevation the block draws the outer frame, the curved arch geometry, the shutter panels with their glazing, and the opening indication that marks it as openable. In plan it shows the frame set in the wall and the leaf swing.
The download keeps the frame, the arch, the glazing and the swing on sensible layers so you can control them separately — screen back the glass, freeze the swing arc, or recolour the arch line for a presentation elevation. Because the arch is true geometry rather than an approximation, it scales smoothly and prints cleanly at any elevation scale.
Semicircular and segmental arch heads
Roman windows come with different arch heads. A full semicircular arch springs from the top of the rectangular opening and rises to a height equal to half the width — the classic 'Roman' look. A segmental arch is a flatter curve, a portion of a larger circle, used where a lower, gentler head suits the elevation. Both read as arched windows but give quite different proportions.
The head you choose changes the character of the façade: a full semicircle is formal and emphatic, a segmental head is calmer and sits more quietly in a wall. Draw the head that matches the architectural language of the scheme, and keep the arch on its own layer so you can adjust the curve without disturbing the shutters below.
Typical proportions to design around
An arched window's proportions come from the rectangular opening below and the radius of the arch above. For a full semicircular head the arch height is half the opening width, which links the two dimensions directly; for a segmental head the rise is shallower. The sill height above the floor, the overall head height and the shutter leaf widths follow from the elevation and the room behind.
Treat these as design-around ranges and confirm the real opening size, arch type and sill height against your project and the chosen product. The block is drawn to a believable module so the arch and the shutters look correctly proportioned the moment it lands in your elevation, but the final dimensions belong to the project.
How to insert and place the window
The block is in millimetres. Insert at scale 1 in a millimetre drawing, 0.001 in metres, or set INSUNITS so AutoCAD rescales automatically. On an elevation, snap the window into the arched opening you have drawn in the wall, aligning the sill to the right height and the arch to the head detail. On a plan, set the frame within the wall thickness and check the shutter swing.
If your opening differs, scale the block to fit, but watch the arch: for a full semicircle the head height must stay equal to half the width, so scale X and Y together to keep the curve true. Keep the opening indication facing the actual swing direction, and record the window in your schedule with its reference, size and arch type.
Where Roman windows are used
Roman and arched shutter windows belong to classical, Mediterranean and colonial architecture: villas and traditional houses, resorts and hotels, churches and civic buildings, and conservation or pastiche schemes that reference a historic style. The arched head is a deliberate stylistic move that signals formality and tradition on an elevation.
Pair the block with the matching rectangular and segmental windows, doors and cornice details so the elevation reads as a coherent classical composition, and bring in sliding or openable Roman variants from the windows category where the design varies. On a traditional elevation, a correctly-drawn Roman window does a great deal to set the architectural tone.
Layering, schedules and reuse
Put the window on a dedicated windows or openings layer, keeping the frame, arch, glazing and swing separable so you can produce a clean elevation, a glazing layout and a schedule from one set of geometry. An annotation layer for the window reference and dimensions keeps labels under control.
Arched windows often repeat across a classical façade, so a tuned Roman shutter block is worth saving to your library once its proportions match your specification. WBLOCK the tuned window so every instance is identical and the schedule count is reliable, and tag each with a type reference so a window schedule can be extracted straight from the drawing rather than counted by hand.

Questions
Frequently asked
Is the Roman shutter window 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 work.
What makes a window 'Roman'?+
A Roman window has an arched head — usually a full semicircle, sometimes a flatter segmental curve — above a rectangular opening. This block is the shutter version, where hinged leaves below the arch open for ventilation.
How do I keep the arch true when resizing?+
For a full semicircular head, scale X and Y together so the arch height stays equal to half the opening width and the curve remains a true semicircle. Scaling the axes unequally would distort the arch into an ellipse.
Does it include plan and elevation views?+
It is drawn to read in both: the elevation shows the arched head, shutters, glazing and opening indication, and the plan shows the frame in the wall with the leaf swing. Use whichever view your drawing needs.
