Implement AP242 STEP geometry importer for BRL-CAD

[brlcad]

Outline

Implement a geometry importer for the ISO 10303 STEP AP242 standard.

Details

BRL-CAD has geometry import support for STEP AP203 (v1), but AP242 has emerged as its industry replacement. This project entails implementing as comprehensive import support as possible in BRL-CAD.

In order to track implementation progress and manage development risk, you will need to track implementation coverage by setting up a dashboard similar to what is used by the CAx-IF -- it can be a simple text file or web page.

Existing conversion support can be examined for AP203 and other formats in BRL-CAD's repository under src/conv/step

Expected Outcome

New AP242 importer that converts STEP entities into BRL-CAD's .g geometry file format.

Future Possibilities

AP242 export support...

Size

This project can be scoped medium (175h) or long (350h) depending on your familiarity and expertise, or you can propose a subset of entities in a shorter timeframe (note though that advanced boundary representation entities should be prioritized).
