Getting started

Before you begin

• Use the approved local development build targeting Revit 2025 / .NET 8. Revit 2022 onward is a future compatibility requirement, not current coverage.
• Have the Codex ribbon registered by the prototype maintainer. This help site is not an installer or a download channel.
• Use a disposable project based on the appropriate firm template. Do not run conversion on production documents until the host-validation gates pass.
• Have approved existing line styles, text types, and filled-region types in that project. Codex does not manufacture replacement styles.

If the ribbon is missing, follow the ribbon troubleshooting steps.

Prepare a DXF

1. Use your normal CAD editor's manual SAVEAS workflow to save a copy as DXF (AutoCAD 2000 or newer). Direct DWG reading is not implemented.
2. Keep firm-standard layer names intact.
3. Put the detail in model space. Paper-space details are not read.
4. Verify millimeter, inch, or foot insertion units. For a unitless DXF, you must explicitly choose the actual source units during conversion.
5. Review supported input. Mapping a layer does not make an unsupported entity convertible.

Codex does not launch or automate AutoCAD. The original CAD file is not modified. Keep real CAD and Revit files local and outside the documentation repository.

Prepare Revit

1. Open the disposable project, not a family document.
2. Confirm drafting views are available.
3. Use Codex > Mapping > Create Mapping to select the DXF and save an explicit layer mapping. Follow the mapping walkthrough.
4. Use Codex > Details > Convert CAD and follow the conversion walkthrough.

For initial host verification, ask the maintainer for the wholly synthetic test input. Do not substitute a client drawing for a smoke test.
