Finding issues in BIMcollab ZOOM

Finding issues in BIMcollab ZOOM

By creating a combination of models (created by different disciplines) you can visually detect conflicts between these models. Next to this, ZOOM has Smart views that can automate identifying and coloring components based on defined or undefined properties. With a license, you also have the possibility to perform a Clash detection in the federated model, from which you can easily create issues.
Below we describe how you can validate models and point clouds in ZOOM using:
  1. Visual analysis
  2. Automated analysis
Start by adding the required models that need to be validated to BIMcollab ZOOM, and connect to your project on BIMcollab Cloud.
You can also add the models to a shared folder, which can be linked to the project on BIMcollab Cloud. For more information, read the article Set up the Project folder to link shared files to a project.

Visual analysis

Use the 3D view and navigate through the models to perform a visual check. Use My view, show or hide components, use quick search to isolate specific models or sets of components, and get a clear view of a potential conflict. Create an understandable viewpoint as a basis for your issues. 

Automated analysis

In BIMcollab ZOOM, there are several automated ways to validate your model.

Smart Views

BIMcollab ZOOM Smart views can be created to personalize the display of components based on their properties, to make it easier to check models for specific requirements. You can color code or group components based on specific properties, or visualize components that miss specific properties.
Smart views are easy to use, and can be saved and exchanged for structured use throughout a team.

For more information on Smart views, consult the article Basics of making Smart views.

Viewing the results from Smart views

When you use the Auto color option in the Smart views, an Auto color legend is generated. Use the legend to understand the color code which was applied to the model by the Smart View, and view and isolate the components for every seperate color.

Clash detection

Use clash detection to locate colliding or duplicated components. You can choose predefined groups of components and set tolerances.

Clash detection is only available with a ZOOM license.
To know how to perform a Clash detection in BIMcollab ZOOM, go to the article How to perform a clash detection with BIMcollab ZOOM.

Creating issues

After validating your model, visualize the problematic areas or components by using additional filtering, section planes and a good camera viewpoint. You can add dimensions and annotations to the view, and color components to clarify the problem. When the view is satisfactory, follow these steps to create an issue.
  1. Go to the Issues tab
  2. Click the  button to add a new issue, or right click in the 3D view and choose 'Add issue'

  3. Fill in the Title and other fields
  4. The active view will be used as a viewpoint for the issue. You can also a insert a snapshot from a folder on your computer  or from the clipboard 
  5. Choose which components are saved in the viewpoint, and whether the selection and any colors that have been added to the visible components are saved
    Save only what is necessary in the issue viewpoint
    When creating a new issue, you can select which elements should be saved in the viewpoint:
    1. Visible components
    2. Selected components
    3. None = Shows entire model
  6. If necessary, fill in the names of the team members you want to notify about this issue
  7. Hit the 'Save' button and the issue will be created

Any annotations and section planes that are visible in the viewpoint will also be saved in the issue.
For more information on how to create and edit issues in BIMcollab ZOOM, consult the article Creating and editing issues in BIMcollab ZOOM.


When all your results are documented to issues, sync them to your BIMcollab project. Click the 'Synchronize project' button. The issues can now be viewed in Revit, Tekla, ARCHICAD, Solibri, Navisworks and more, with the help of the BCF Managers, as well as in your project on BIMcollab Cloud.
Assigned team members will receive an automated notification regarding the issues that you raised.

Handling revisions

When you connect to a project on BIMcollab Cloud, which has a linked project folder, or when you open a ZOOM project (BCP-file), BIMcollab ZOOM will reload all models. If the models are overwritten with a newer version, ZOOM will automatically show the up-to-date models, provided the models have the same name as the earlier version.
If your workflow adds revision numbering to the filenames, this means the older versions of the models are not automatically overwritten.
If the old models have been removed from the shared folder, they will be shown in red in the model tree. 
  1. When using the linked project folder workflow, the new models will be shown in grey in the model tree. Right click on them and choose 'Load model'. Right click on the old models and choose 'Remove from project'

  2. When using an offline workflow with a BCP-file, you can update the models manually from the navigation tab. Select the old model in the Navigation tab, click on 'Update model' and browse to the revised file
