3D Repo supports 4D Sequence playback, allowing you to add time-sensitive Issues and Risks to your project. Check out how to export your sequence to 3D Repo and which functions are supported.

Export .SPM File

3D Repo supports Synchro .spm files and there are 3 options available to you for generating the .SPM files (option 1 is the optimal & preferred method):

Option 1. Synchro Desktop File Export

  • In the Synchro desktop application, open the 4D model you wish to upload to
    3D Repo

  • Select File > Export > 3D

  • When specifying a filename, select Synchro SPM (.spm) from the File Type options menu

  • Under the Export Mode, select Export Animation

  • Select the dates from your Synchro programme you wish to use in 3D Repo

  • Click the Next button

  • Under Select Animation select the Animation sequence you want to upload*
    *Note If you wish to upload the entire 4D sequence, select None

  • Click Export to export your .spm file

  • Now you can upload it at 3drepo.io

  • Load your Synchro .sp into the Synchro Link Desktop Application

  • Select File > Export > SPM

  • Specify any filters you wish to apply to your 4D Export and click Next

  • Keep all elements selected for export, unless there is sensitive data you don’t want to share, then click Next again

  • Load your Synchro .sp into the Synchro Link Desktop Application

  • Create your Synchro SPM (.spm) by using the /spm/publish/begin endpoint

  • Access your new .spm file by using the /spm/publish/download endpoint

  • Upload to 3D Repo using the Upload Model endpoint
