Drop & View GLB Exporter v0.5.0-beta

Drop & View GLB Exporter v0.5.0-beta

This beta improves material compatibility and the appearance of curved Archicad geometry. The active Archicad 3D window remains the complete source of exported geometry and appearance.

Requirements

• Archicad 28 or 29
• Apple Silicon Mac (arm64) with macOS 26 or later, or Windows 11 PC (x64)

Highlights

• Exports every visible body in the active Archicad 3D window without requiring an Archicad selection.
• Preserves visible 3D cuts, effective surface colours, transparency, embedded textures, texture size and rotation.
• Converts TIFF surface textures to embedded PNG data during export, alongside direct PNG and JPEG support.
• Smooths shading across edges marked as curved by Archicad while preserving hard edges and the original polygon count.
• Preserves the result of active Graphical Overrides.
• Supports major architectural, structural, library-object and site element families.
• Includes visible doors, windows and skylights directly from the active 3D model.
• Groups GLB meshes by effective surface.
• Continues past invalid polygons where possible and reports skipped geometry.
• Uses the embedded texture as the glTF base colour without applying Archicad's surface colour a second time.
• Builds Archicad 28 and 29 packages for macOS and Windows from one GitHub Actions release workflow.
• Separates GLB serialization from Archicad model collection and allocates glTF buffer indices automatically.
• Adds portable GLB and triangulation regression tests for Debug and Release builds on macOS, Windows and Linux.
• Adds portable regression tests for curved-surface normal generation and hard-edge preservation.
• Applies stricter compiler warnings while keeping required Archicad SDK exceptions narrowly scoped.

Beta notice

This build is intended for evaluation and feedback. Compare every exported model with the source Archicad 3D view before professional or client use. Please report reproducible problems through GitHub Issues without uploading confidential project material publicly.

Installation

Open the DMG or extract the Windows ZIP, enter the folder matching your Archicad version, then add DropViewGLBExporter.bundle or DropViewGLBExporter.apx from Archicad's Options > Add-On Manager.
