3D Viewer component installation

Note
  • Using the 3D Viewer components requires a separate license in addition to the ShareAspace license.
  • The file preview component and the single component Web 3D viewer are both agnostic to the ShareAspace configuration used by a space however viewing non-monolithic assemblies in the web 3D viewer requires a configuration based on the predefined ShareAspace information capabilities.

Components

Component Installation package Description
Web 3D Viewer 3DViewer-x.y.z.bbb.msi External extension web module for 3D viewing of single geometry as well as full geometry assemblies.
CAD converter CadConverter-x.y.z.bbb.msi ShareAspace Nova extension that provides two features. 2D file preview of supported formats. Light weight 3D preview conversion of supported formats and caching of light weight files. Conversion is executed when a file is created in the managed file vault of a space (through API and import).
Streaming cache service StreamingCacheService-x.y.z.bbb.msi Server side component for generating 3D viewing models and providing these to clients (web browsers) via a web socket stream.
HOOPS Communicator HOOPS_Communicator_2024.1.0_Windows.zip Installation package for HOOPS Communicator from Tech Soft 3D, see HOOPS Communicator.

Installation

Web 3D Viewer

  • Run installer 3DViewer-x.y.z.bbb.msi.
  • The default installation location is C:\Program Files\Eurostep\ShareAspace\3DViewer.
  • Running the MSI deploys an IIS web application 3DViewerWeb and an application pool 3DViewer.

CAD converter

  • Run installer CadConverter-x.y.z.bbb.msi.
  • The default installation location is C:\Program Files\Eurostep\ShareAspace\CadConverter.
  • Running the MSI deploys an IIS web application CadConverter and an application pool CadConverterPool.

Streaming cache service

  • Run installer StreamingCacheService-x.y.z.bbb.msi.
  • The default installation location is C:\Program Files\Eurostep\ShareAspace\StreamingCacheService.
  • Running the MSI deploys an IIS web application StreamingCacheService and an application pool StreamingCacheServicePool.

HOOPS Communicator

  • Unpack the HOOPS_Communicator_2024.1.0_Windows.zip ZIP archive. e.g. at C:\HOOPS_Communicator_2024.1.0.
  • Create a license.txt file and paste the license key to it. e.g. at C:\HOOPS_Communicator_2024.1.0\license.txt.
  • Setup work folders for file conversion and storage folder for conversion cache. Preferably on a specific storage drive. e.g.
    • F:\3dviewer\model\.
    • F:\3dviewer\temp\.

Configuration

For the configuration examples in this section it is assumed that

  • The 3D viewer components are hosted at the fictive address https://xyz.eurostep.com.
  • The HOOPS Communicator ZIP archive is extracted at C:\Program Files\Eurostep\Hoops\.\
  • The HOOPS Communicator license is placed at C:\Program Files\Eurostep\Hoops\license.txt.
  • There is a separate drive F:\ for caching converted files.

Web 3D Viewer
