XGRIDS Pro Guide™ / Module 9: LCC Studio

9.7 Export Formats and Sharing

LCC, PLY, USDZ, 3D Tiles, and mesh export formats, web publishing, and the specific requirements for USDZ and 3D Tiles that must be verified before reconstruction begins.

Section 1

Choosing the Right Format

Full cross-pipeline comparison with file sizes and compatible platforms: This page covers LCC Studio export procedures and format-specific requirements. For a side-by-side comparison of all LCC Studio and LixelStudio formats, typical file sizes for a 20-minute scan, third-party platform compatibility, and a decision guide for matching deliverables to export paths, see 10.6 Platforms and File Types.

Format

File Size

Best For

Constraints

LCC

Smallest (20 to 40% of PLY)

Delivery and archiving within the XGRIDS ecosystem. LCC web publish. LCC for BIM in Revit.

Export is a folder, not a single file. Deliver the entire folder (zipped) to clients. Requires LCC Studio (free) or a platform with native LCC support (SuperSplat, Splat Labs).

PLY

Large

Maximum third-party compatibility. Standard 3DGS format. Use when the recipient uses tools outside the XGRIDS ecosystem.

Large files. Typically 3 to 5 times the size of an equivalent LCC file for the same model. Premium license required.

USDZ

Small

NVIDIA Omniverse. Lightweight cross-platform 3D format. Preserves Gaussian-ellipsoid data with consistent visuals.

Requires firmware ≥3.0, single-scene reconstruction only, Portability must be Off. All three must be met simultaneously.

3D Tiles

Variable

Web GIS and digital twin platforms. Loads directly in Cesium. OGC 3D Tiles 1.1 standard for WebGIS integration.

Requires absolute coordinates (RTK or GCP data). Maximum 4 million Gaussian points. Exceeding the point limit is not supported.

Mesh (OBJ / PLY)

Medium

CAD workflows requiring triangulated mesh geometry. Geometry-only representation without color or material data.

No textures. No color data in the mesh output. Use only when the downstream workflow requires a mesh surface, not a Gaussian model.

PLY export requires the Premium license ($2,500/yr). The Free and Basic tiers export LCC format only. If a client or delivery platform requires PLY, confirm you have the Premium license before committing to that format. Verify the recipient's format requirements before quoting. For the full list of third-party platforms that accept PLY versus LCC, see 10.6 Platforms and File Types.

Section 2

Web Publishing

LCC Studio includes a one-click Publish function that uploads the model to XGRIDS cloud hosting and generates a shareable web link. The link can be opened in any modern browser without installing software. This is the fastest way to share a completed model with a client for review.

Published models can be managed in LCC Studio under My Captures > Generated. Publishing does not replace local export, the model is also retained locally in LCC format. Published links can be revoked through the publish management interface.

Web publishing requires an internet connection and an active XGRIDS account. For clients with data sensitivity requirements, deliver via local export in LCC or PLY format rather than a web-hosted link. Confirm the client's data handling requirements before publishing.

Third-party delivery platforms: XGRIDS web publish is not the only option for browser-based model sharing. Third-party platforms such as Splat Labs, 3DVista, and ATIS.cloud accept LCC or PLY files and offer additional features including measurement tools, access controls, guided tours, and white-label branding. For a comparison of delivery platform options and their format requirements, see the decision guide in 10.6 Platforms and File Types.

Section 3

USDZ Export Procedure

USDZ export is only available when three conditions are simultaneously met. Verifying all three before starting reconstruction avoids discovering the limitation only after hours of processing.

USDZ Pre-Export Checklist

Firmware version is 3.0 or higher. Check device firmware in LixelGO or LCC Scan before the scan. Firmware cannot be updated after the scan has been taken if USDZ export is required.
Reconstruction mode is Single Scene. USDZ export is not available for Map Fusion, Aerial-Ground Fusion, or Aerial Reconstruction modes. If the project requires fusion, USDZ is not an available output format.
Portability is set to Off. USDZ export requires Portability disabled during reconstruction. If the project was processed with Portability On, it must be reprocessed with Portability Off to enable USDZ export.

Section 4

3D Tiles Export Procedure

3D Tiles export produces a tiled dataset loadable in Cesium and other WebGIS platforms. It requires absolute coordinates and a model with 4 million Gaussian points or fewer.

3D Tiles export requires absolute coordinates. A scan processed without RTK or GCP data has no real-world coordinates and cannot be exported to 3D Tiles. Georeferencing must be present in the scan data. It cannot be added to the model after reconstruction.

To export, select the generated model in My Captures, choose Export, and select 3D Tiles from the format options. Confirm the model is within the 4 million Gaussian point limit before starting, and the export will fail on models that exceed this limit without providing a useful error message in all versions of LCC Studio.
