Application links

Autodesk 2026 family support

MRS-1768

Meridian Server supports the Autodesk 2026 product family. This ensures engineering and design workflows continue without interruption when you upgrade to the latest Autodesk tools.

  • AutoCAD 2026 compatibility: Use AutoCAD 2026, Plant 3D 2026, and Civil 3D 2026 with Meridian Server. All ARX functions work across these applications. Meridian does not yet support Plant 3D asset functionality for the 2026 family. We will add this in a future release.

  • Civil 3D shared folder sync: Civil 3D shared folder sync imports files correctly into the vault using both sync methods.

  • RealDWG 2026: Meridian Server setup installs RealDWG 2026, which replaces the RealDWG 2025 version.

  • AutoCAD 2026 rendition engine: Use native AutoCAD 2026 as a rendition engine in Meridian Publisher for accurate document rendering.

Autodesk 2027 family support

MRS-14706

Meridian Server supports the Autodesk 2027 product family. This ensures engineering workflows remain compatible with the latest Autodesk releases.

  • AutoCAD 2027 add-in support: The installer deploys the AutoCAD 2027 add-in (AmAcad2027) to the server and client. This add-in supports AutoCAD 2027 and AutoCAD Plant 3D 2027. Meridian does not yet support Plant 3D asset functionality for the 2027 family. We will add this in a future release.

  • RealDWG 2027: Meridian Server setup installs RealDWG 2027, which replaces RealDWG 2026.

  • AutoCAD 2027 rendition engine: Use native AutoCAD 2027 as a rendition engine in Meridian Publisher for accurate document rendering.

  • Backward compatibility: Existing Publisher features remain compatible with AutoCAD 2026 to ensure workflow continuity.

Authentication

MRS-14705

Authenticate across Meridian desktop client interfaces using the industry-standard Okta identity provider. This update provides enhanced security and a seamless login experience across the ecosystem.

  • Okta identity provider support: Sign in using Okta authentication across the Site Cache client, Application Integration, and Application Add-Ins. Your organization can use Okta to manage access securely and consistently.

  • Application Integration: When you open a vault in Application Integration, you authenticate via Okta. On successful authentication, you can access the documents in your vault. If authentication fails, an error message appears.

  • Site Cache client: When you open the Site Cache client, you authenticate via Okta to manage your local workspace.

  • Application Add-Ins: When you open a vault through an Application Add-In, you authenticate via Okta. On successful authentication, the vault opens. If authentication fails, an error message appears.

AD group-based license restrictions for Meridian Subscription License Server

MRS-324

The Meridian Subscription License Server now supports license restrictions based on Active Directory (AD) group membership. This enhancement aligns with the features in the classic License Server. Control license allocation by department or role using AD groups configured in the registry.

Key features:

  • AD group-based restrictions: Restrict licenses to users within specified AD groups to control access to product codes.

  • Consistent behavior across license servers: Enforce restrictions identically to the classic License Server for unified license management.

  • Efficient license allocation: Manage license distribution effectively to ensure only authorized users claim licenses, which enhances security and compliance.

This update provides the same level of control and flexibility in license management for subscription licenses as is available for concurrent licenses.

Configure IFilter ClassIDs for Windows Server 2022

MRS-296

Add specific ClassIDs to the Meridian indexing service configuration to enable full-text indexing for Office documents and other formats. This update provides greater flexibility for indexing in your environment.

Due to technical restrictions in the Windows Search Indexer, you must patch the Meridian DLL with these ClassIDs to integrate with Windows Search. Please contact Accruent Support for assistance with this configuration.

Implement Entra ID authentication in Meridian

Meridian Enterprise now supports Microsoft Entra ID authentication for publishing to Microsoft SharePoint and SharePoint Online.

  • Entra ID authentication: This feature incorporates X.509 certificates as additional credentials alongside the existing Client ID and Client Secret to provide a secure authentication flow.

  • Certificate management: Upload X.509 certificates for SharePoint communication using the new Upload button.

  • Technical integration: Meridian Enterprise uses Microsoft SDKs and libraries to streamline development and ensure compatibility with SharePoint.
