## New API for Mesh Access

We’re introducing a major enhancement aimed at making the process of retrieving meshes and geometry simpler in Exchange. This enhancement provides developers with a refined approach for accessing geometric data, streamlining the creation and manipulation of models.

The addition includes:

- A sample application provided within the package.
- A new version of our basic viewing tutorial which empowers the API additions.
- A C Module, /api/c/group__a3d__rihelpers which contains:
  - The `A3DMeshData` structure
  - The `A3DRiComputeMesh()` function

More to Come

This addition is part of a bigger initiative that will add more higher level features in our API to provide you with common application-level use cases without masking the underlying set of functions.

## Support for C#

This new release comes with the addition of a C# overlay.

For more information, see C# API Primer.

## Fixed Bugs
