DXF to 3D for extruded & pultruded profiles
A profile is a 2-D section extruded along a straight line — so turning its DXF into 3D doesn't require a mesh-guessing AI. Dimviz sweeps the exact cross-section into a clean, interactive 3D model you can orbit, whose silhouette is your section, and computes the section's engineering properties at the same time. Try it on a real section below.

Extrusion, not hallucination
Generative image-to-3D tools invent a mesh and hope it resembles the input. For an engineered profile that's unacceptable — the wall thickness, the fillet, the overall depth all matter. Dimviz treats the DXF outline as ground truth and extrudes it, so the 3D view is a true projection of your geometry, exact to the dimension.
You get the numbers too
Because the section is known exactly, the same DXF that produces the render also yields area, moments of inertia, section moduli and weight per metre. One input, a picture and a datasheet — consistent by construction.
Where a full mesh still helps
For end features, cut-outs or assemblies you'll still want a solid modeller. Dimviz targets the 95% case of profile marketing and specification — the constant-section render and its properties — where a deterministic extruded 3D view is faster and more trustworthy than a general mesh-guessing pipeline.
FAQ
How do I convert DXF to 3D?+
Upload your .dxf in the tool — Dimviz reads the closed section outline (polylines, arcs and circles), extrudes it into an interactive 3D render and computes its properties. You can also build the section parametrically. Export as high-resolution PNG.
Is this real 3D?+
Yes — the section is extruded into a real 3D mesh you can orbit and zoom, rendered with a depth buffer so faces occlude correctly and nothing clips. It is not a guessed mesh: the geometry is exactly your section, so it stays dimensionally faithful.
Does it work for FRP and aluminium extrusions?+
Yes — pultruded FRP, aluminium extrusions, steel and PU-FRP window profiles are all supported, with material-correct weight and finish.
