CAD to image, for profiles
Turn a profile's CAD cross-section into a clean, presentation-ready image without opening a full rendering suite. Dimviz reads the section geometry and produces a dimensioned drawing and an interactive 3D render — both exact projections of the real shape — plus a spec sheet. Load a section below and export a high-resolution PNG in seconds.

From a section to a shippable image
Firing up CAD, exporting to a renderer, setting up lights and a camera just to picture one extrusion is overkill. Because a profile's silhouette is fully defined by its section, Dimviz can generate a consistent isometric directly — same camera, same light, same material language across your whole range — so your catalog looks like one product family instead of a dozen ad-hoc screenshots.
High-resolution PNG export
The interactive 3D render and the dimensioned drawing both export as high-resolution PNG — supersampled well beyond screen resolution, ready for a datasheet, a web hero or a large-format print. The render is a true depth-buffered extrusion, so edges stay crisp and nothing clips or z-fights the way a 2.5D fake would.
Import your DXF, or build it parametrically
Upload a .dxf and Dimviz reads the closed section outline directly — polylines, arc bulges and circles — classifies the largest loop as the outer boundary and the rest as holes, and computes the exact properties. Units are read from the file (or set them manually). PDF tracing and perspective-corrected photo input are next on the roadmap; a photo is always a reconstruction calibrated to one baseline dimension you confirm, never a sub-millimetre claim from a phone camera.
FAQ
How do I convert a CAD file to an image?+
Upload the .dxf of your section (or a CSV/Excel of X,Y coordinates, or build it parametrically), choose a material, and export the 3D render or dimensioned drawing as a high-resolution PNG. Dimviz reads the outline directly, so the image matches your geometry. PDF import is on the roadmap.
Is the image dimensionally correct?+
Yes — the render is a true extrusion of the section you input, depth-buffered so nothing clips, and the dimensioned drawing shows the true overall width and height. What you draw is what you get.
What formats can I export?+
High-resolution PNG today, for both the interactive 3D render and the dimensioned drawing. Multi-page PDF datasheet export is planned.
