How to Filter a Revit Model by Visibility of a View and Export for iTwin Consumption


Introduction

Many of our users from the building industry use Revit as their primary design tool. They often need to extract part of (or filter) an RVT file for consumption in iTwin-powered solutions such as SYNCHRO Modeler, SYNCHRO Control (a.k.a. Bentley Infrastructure Cloud - Build) and many more.

Instructions

Step 1 – Export/Extract a filtered model 

Option 1 – Use a 3D view and save an IFC file (Recommended)

  • Create a 3D view
  • Adjust visibility by Category/Element to your needs
  • If you are to export Parts, make sure to set Part Visibility of the view to "Show Parts"

  • Go to File > Export > IFC
  • As IFC Export Options shows up, click “Modify setup …”
  • Go to Additional Content > Check “Export only elements visible in view”

Option 2 - Use a 2D view and save as a new RVT file

  • Create a section view
  • Adjust visibility by Category to your needs
  • Save a visibility template and apply it to the section view you just created
  • Adjust view scope
  • Review in a 3D view
    • Open a default 3D view
    • Right click on view cube > Orient to View > Sections > Select the section you just created
    • Apply the visibility template
    • Review visibility and adjust the template if needed
  • Right click on the section view in Project Browser > Save to New File……
    • If it is grayed out, just place a dimension annotation, and it will be enabled.
  • You may encounter error messages like these:

       This is due to the fact that the constraint elements are not visible in this view. You may try making the constraint elements visible or replace them with work planes; otherwise, we would recommend Option 1.

Step 2 – Upload Exported Model Files to Bentley Infrastructure Cloud

  • Go to your Bentley Infrastructure Cloud project
  • If you are using ProjectWise Design Integration (PWDI), save your models to your chosen location in the PWDI sever and connect the data source to the Bentley Infrastructure Cloud (BIC) project.
  • If you are not using PWDI, upload your models to the Document space of your BIC project

Step 3 – Create an iModel

Step 4 – Consume the Model in Your iTwin-Powered Solution(s) 

  • Now you can go to the iTwin-powered solution of your choice and access the iModel.

Step 5 – Update Model Changes

  • If any changes to the models occur, re-export and upload the modified model files to the same location without changing the file names and create a new version (See this article for Working with Document Versions).
