Free tool
Online DXF viewer
Open a DXF drawing straight in your browser: pan, zoom, and inspect it in seconds. No CAD software, no signup, and your file never leaves your device.
View any DXF, right in the browser
A DXF (Drawing Exchange Format) file is the common export from AutoCAD, Vectorworks, and most CAD tools. Normally you need heavy software to open one. This viewer renders the drawing's 2D geometry (lines, polylines, circles, arcs, splines, and block references) on a canvas you can pan and zoom, so you can check a floor plan or an equipment footprint without opening CAD.
Private by design
The file is read and drawn entirely on your device. Nothing is uploaded to a server, so you can open client drawings without them ever leaving your machine.
Good to know
- Supports ASCII DXF. Binary DXF and 3D solids are not rendered.
- Very large engineering drawings with thousands of dimensions or hatches may show only their line work.
Planning an actual install? Avitly imports vendor DXF outlines and renders every device at its true footprint on a calibrated floor plan, then turns those placements straight into a quote.
Common questions
Do I need AutoCAD to open a DXF file?
No. DXF is an open interchange format that Autodesk publishes, which is exactly why it became the way drawings move between programs. This viewer opens it in the browser with nothing installed, and free desktop options such as LibreCAD and QCAD can edit it if you need to make changes.
Is my drawing uploaded anywhere?
No. The file is parsed in your browser and never leaves your device. Nothing is sent to a server, stored, or logged, so you can open a client floor plan under NDA without it going anywhere.
What is the difference between DXF and DWG?
DWG is AutoCAD's native binary format and is proprietary. DXF is the documented text-based format meant for exchanging the same drawing data between different applications. If someone sends you a DWG and your software will not open it, ask them to export a DXF, since every CAD package can write one.
Why does my floor plan open at the wrong scale?
DXF stores coordinates as bare numbers and only records the drawing units in a header field that many exporters set wrongly or leave blank. That is why a plan can appear a thousand times too large or small. Always calibrate against a known dimension, a door width or a marked wall run, before you measure anything off it.
Which DXF versions are supported?
The common ASCII DXF versions from R12 onward, covering what architects and CAD users typically export. Binary DXF and heavily proprietary entities may not render fully. If a drawing looks incomplete, re-export it as ASCII DXF R12 or 2000, which is the most widely compatible target.
How do I get a floor plan from an architect?
Ask for a DXF or DWG export of the plan view, ideally with furniture and dimension layers included, and confirm the drawing units. A PDF is workable but you lose true geometry and have to scale by hand. If all you can get is a PDF or an image, calibrate it against a known dimension before placing anything on it.
Design it once. Sell it, install it, service it.
Avitly runs the whole install off one floor plan: quote, client-signed offer, bill of materials, rack layout, then device credentials and tickets after handover. Presales to maintenance, no re-entry.
