Cotio is a Windows and macOS tool that says it converts STEP parts or assemblies into dimensioned PDF and DXF manufacturing drawings on your computer.

Landing page captured for the 2026-10-15 issue.

For: Sheet-metal fabricators and small engineering teams
Worth noticing: Its sheet-metal workflow uses configured K-factors and tool radii, then separates DXF cutting contours from bend lines.

Field notes

The page says quantities for assemblies are read from the CAD tree, with a separate drawing and line for each distinct part. It also describes five plan languages and revision entries that retain a date and reason. Those details suggest a workflow aimed at carrying model information into fabrication and supplier handoffs, not just producing a drawing view.
