Open or paste an SVG and convert its paths and basic shapes into an R12 DXF file made of polylines and lines.
The converter parses SVG path data (M, L, H, V, C, S, Q, T, A and Z commands) and samples every curve and arc into short straight segments, because DXF polylines have no curves. Basic shapes (rect, circle, ellipse, line, polyline and polygon) are converted to polylines the same way. The result is written as a DXF R12 file with a minimal header and all geometry on layer 0 as LWPOLYLINE or LINE entities. Fills, strokes, gradients, text, images, clipping and transforms on nested groups are not carried over, so check the entity counts below and open the DXF in CAD software before cutting or machining.
Why does the DXF contain so many points? Curves and arcs are sampled into straight segments so the shape survives in a polyline-only file. More points follow the original curve more closely; a circle, for example, becomes a 48-sided polygon.
Will colours and layers from my SVG appear in the DXF? No. Everything is written on layer 0 with no colour information. Split the design and convert each part separately if separate CAD layers are needed.
