Technical note

Before you convert CT1 to DWG

CT1 is made of pixels and DWG stores geometry, so the conversion traces the image into real lines, arcs and polylines. The result is editable in CAD: entities can be selected, snapped to and measured, rather than a bitmap wrapped inside a DWG container, which is what a viewer or a lightweight converter usually produces. It is still derived geometry, so expect contours rather than a structured drawing. Dimensions, blocks and meaningful layer names were never in the CT1 to begin with. How good the result is depends almost entirely on the CT1 going in. Clean line art, a logo or a drawing scanned at 300 dpi or more traces into geometry you can work with. A photograph does not: continuous tone has no contours to follow, so tracing it produces thousands of tiny shapes and a file nobody can edit. Scan or export at the highest resolution available, and prefer a lossless original, because compression artefacts along an edge become ripples in the traced path.

I needed to convert DWG to DXF for a laser cutter, and reaConverter did it flawlessly. The geometry remained intact, and the line weights were preserved. I've tried free tools, but they always mess up arcs. This is the only one I trust.
