Manage DWG & DXF Layers
Open a DWG or DXF drawing and take control of its layers — toggle visibility, freeze or lock layers, and change their colors with a live preview. Entirely in your browser, completely free.
Why manage layers with AnyDocFlow?
Toggle layer visibility
Hide or show any layer with a single click. The preview updates instantly, and layers you switch off stay off in the exported drawing.
Freeze and lock
Freeze layers you don't need regenerated, or lock layers against accidental changes — both states are written back into the exported DXF.
Change layer colors
Pick a new color for any layer from the AutoCAD Color Index (ACI) palette. Swatches use the exact ACI values, so the exported file matches what you chose.
Live drawing preview
Every change is re-rendered on a pannable, zoomable canvas, so you can see exactly how visibility, freeze, and color states affect the drawing.
DWG and DXF support
Open both .dwg drawings (through a WebAssembly converter) and .dxf files directly. No CAD software, no plugins, no installs.
No upload, fully private
Everything runs locally in your browser. Your drawings never leave your device, so the tool keeps working even offline after it loads.
What is a CAD layer manager?
CAD drawings are organized onto layers — named levels that group related geometry, each with its own color, visibility, freeze/thaw, and lock state. A floor plan, for example, might put walls on one layer, furniture on another, and annotations on a third, so you can work on the furniture without the walls cluttering the screen. A layer manager reads that layer table from a DWG or DXF file and lets you take control of it: hide a layer, freeze one that is slowing regeneration, lock one you do not want disturbed, or change a layer color. This tool reads both DWG drawings (through an in-browser WebAssembly converter) and DXF files, shows the drawing live on a canvas, and lists every layer with its current state. Toggle a visibility, freeze, or lock button — or open the palette to change a layer color — and the preview updates instantly. When you export, only the layer table lines of the DXF are rewritten; the geometry and every other byte of the file stay intact.
How to manage layers
Three simple steps — no account, no software, no upload.
Drop your drawing
Drag and drop a .dwg drawing or .dxf file onto the drop zone. It opens automatically and renders on a live, pannable canvas.
Tune the layers
Use the eye, snowflake, and lock buttons to switch visibility, freeze/thaw, and lock states — or click a color swatch to open the ACI palette. The preview updates instantly.
Export the edited drawing
Download the edited file as a DXF. Layer edits are written in place — only the layer table changes, so the geometry stays exactly as it was.
A note on layer edits
Turning a layer off or freezing it keeps its entities in the file — they are simply hidden or not regenerated when the drawing is opened, which is standard DXF behavior. In the on-screen preview, frozen layers are hidden exactly like off layers, matching how a CAD application stops regenerating them. Color changes use the AutoCAD Color Index (ACI); entities with an explicit true-color (24-bit) override keep their own color. DWG inputs are exported as DXF, since a browser cannot write the DWG format back.
