Open CAD files without the CAD suite
Drop a STEP, IGES or BREP solid for an interactive 3D preview, or open a DXF drawing in a dedicated 2D canvas. Layers, extents and entity counts stay readable, and every file is processed on your device.
Files stay on your device
Open a CAD file
STEP, IGES and BREP solids get a tessellated 3D preview. DXF drawings open in a focused 2D canvas with layers, pan and zoom. Mesh exchange files are welcome too.
Drop an STL, 3MF, OBJ or PLY
The first file opens; the rest are added to the pending list
3D solids, tessellated locally
STEP, STP, IGES, IGS and BREP are converted into a preview mesh in a background worker. Orbit, section, measure and check the result without sending the original CAD data anywhere.
DXF drawings in 2D
Lines, polylines, circles, arcs, ellipses, splines, points and text are drawn on a Canvas 2D workspace. Toggle layers, pan, zoom and fit the drawing extents.
One place for exchange files
STL, OBJ, PLY and 3MF files can be opened in the same viewer, so a mixed workflow does not need a second tab or a second tool.
What opens in the CAD viewer
Choose the path that fits the file you have.
3D CAD
STEP, STP, IGES, IGS and BREP. Tessellated to a preview mesh with the original file kept untouched.
STEP · STP · IGES · IGS · BREP
2D CAD
DXF drawings rendered in a dedicated Canvas 2D view with layer visibility and drawing extents.
DXF
Mesh exchange
STL, OBJ, PLY and 3MF open in the same 3D workbench when the job crosses from CAD to print.

DWG needs a conversion
DWG is accepted so the tool can explain the next step clearly, but it is not decoded in the browser. Export DXF or STEP from your CAD application and open that file here. No conversion happens on a server.
Questions, answered
Are CAD files uploaded?+
No. Tessellation, DXF parsing and rendering run in your browser. The original file is never sent to FabKit or a third party.
Can I edit CAD geometry here?+
No. The viewer is for inspection: dimensions, topology checks, sections, measurements and 2D drawing review. Parametric CAD editing and model repair are out of scope.
Why is DWG not rendered?+
A dependable browser DWG decoder is not available under terms that fit this project. FabKit tells you when a DWG is selected and points you to DXF or STEP instead of showing a broken preview.
