Quick Start Guide BIMcollab Model WebViewer

BIMcollab Model WebViewer offers a streamlined way to view IFC models, their properties, and issues in one go. With this powerful tool, you can effortlessly navigate through intricate models while gaining insights into their properties and addressing any issue that arises. You can find the BIM WebViewer by going to your BIMcollab Nexus project and clicking on the Model tab. If the model tab is empty the BIM WebViewer should be set up first. 

BIMcollab Model WebViewer currently supports the following file types: IFC models (.IFC, .IFCZIP)

Setup BIMcollab Model WebViewer

 Following these steps you can find out which viewer is setup in a project or set up a different one: 
  1. Log in to BIMcollab Nexus
  2. Select the desired project where you are a Project Leader
  3. Navigate to the Settings page of the project
  4. Click on 'Integration'
  5. Choose BIMcollab Model WebViewer among the options. 

Explore the features

This article looks into the diverse aspects of the viewer, showcasing how you can use its features to enhance your BIMcollab workflow. The viewer includes four main panels which can be easily hidden or revealed based on your requirements:

1. Navigation panel
2. Property panel
3. Issue panel
4. List panel

These panels are revealed and hidden by clicking on the icons below. You can also click the minus sign on property and navigation panels to hide them.

1. Navigation panel

Navigation panel gives you the option to open models and navigate through them from the "Models" section. Additionally, the panel provides a detailed insight into the constituent components of the models through the "Objects" section.


When the Navigation tab is open, a project leader can click on the load icon to add models to the BIMcollab model WebViewer. Then the models load quickly and are visible in the viewer. Other members of the team then can view the models and work with various available panels and features. You can chose to load or unload a model by switching the toggle next to each model's name.

A project leader should always load the models so the rest of team members can view them on the BIM WebViewer.

Hovering over each model name reveals a menu icon with three dots, providing options to delete or replace the model. Moreover, you can unload all other models except the selected one (load isolated) and focus on one model.

To efficiently manage the loading and unloading of multiple models simultaneously, follow these steps:
  1. Choose models by holding down Ctrl for individual selections or Shift for consecutive selections (begin by clicking on the first model, press Shift, and click on the last one).
  2. Adjust one of the toggle switches to initiate the loading or unloading process. This action will be applied to all the selected models.


In the same panel we have the "Objects" section that allows you to select a specific object category and you can hide/unhide each category by clicking on the eye icon .

To hide/unhide multiple categories
  1. Choose object categories by holding down Ctrl for individual selections or Shift for consecutive selections (begin by clicking on the first model, press Shift, and click on the last one).
  2. Click on one of the eye icons. This action will be applied to all the selected categories.

It is also possible to load spaces and openings by clicking on the gear icon and moving the toggles.

2. Property panel

When the property panel is turned on and an object (or a model) is selected, you will have a list of relevant properties on this panel such as summary, location and IFC property sets. You can scroll down to see the full list and close/open the titles with the arrow icon to adjust the size of the property list.

3. Issue panel

The issue panel provides the functionality to view, create, import, and edit issues. It enables simultaneous viewing of issues alongside the model, and users can apply filters to find specific issues as needed.

4. List panel

If you have a BIMcollab Zoom license, you can create lists in Zoom and share it with your team members. Then the team can view the lists in the BIM WebViewer as well. It's important to note that sharing the results of the list is crucial; merely sharing the list definition will not display the outcomes. 

Tips: Viewpoint customization


In BIM WebViewer, you have the flexibility to create up to six section planes and one section box, providing a comprehensive approach to model analysis.
Located in the bottom menu, this icon enables you to generate section planes with ease. Simply click on the icon and then select a plane within the model to define the direction of the section. The shortcut is to press "3" on your keyboard.
On the same menu, this other icon creates a section box around all of the visible objects in the viewpoint. This box is equivalent to having six section planes turned on at the same time.

When a section appears in the viewer, click on it to reveal the section handle. By selecting this handle, you can move the section back and forth, adjusting it to your desired position.

When a section plane is created and selected, the sectioning tool box appears on the top of the viewer, allowing you to apply more adjustments to this plane.

This icon flips the section plane.

This icon removes the section plane. For instance, if you require only four section planes for your analysis, you can create a section box and easily remove the excess planes, ensuring you maintain your desired four sections. The shortcut is to press "Delete" key on your keyboard.

This icon removes all the section planes if there are multiple of them created.

This icon hides the section planes in the viewpoint. This feature comes useful when you've created your desired section and want an uninterrupted view inside the model.

Object Selection menu

When you select an element, a range of options becomes available. You can hide, isolate, and even apply custom colors to these elements. Additionally, you have the capability to create a section box around the selected elements, providing a focused, in-depth view for analysis.

Hiding elements: The shortcut is to press "space" bar on your keyboard.

Isolate elements: The shortcut is to press "=" on your keyboard.

Create section box around all the selected objects.

Color the selected objects.

The number of selected elements.

Instead of selecting elements one by one you can select a category of elements from the "Navigation panel> Objects" and apply the desired customizations. You can also keep the CTRL key and click on multiple objects, object categories or models to have them selected.

Restore the default viewpoint

There are a few buttons on the bottom menu that can help you eliminate the viewpoint customizations. You can unhide all the hidden elements by clicking the show all icon . Then if you have moved the view away from the model, you can always Zoom to fit with this icon . Lastly, you have the option to go back to the default view by clicking on the restore view icon which reverts back all types of adjustments. For instance, it unhides any hidden elements, applies Zoom to fit and removes any added colors or sections.

Tips: Navigating the model

By making use of the following mouse and keyboard shortcuts you will be able to easily navigate through your federated model.

Besides the orbit mode, there are two additional view modes available while using the BIM WebViewer:

Fly Mode

It helps you to easily position yourself within your federated models, especially in large-scale models. 

Use the "W" and "S" keys to zoom in and out from the model.

Walk Mode

It gives users the experience of walking through the models, particularly useful for closer inspection of internal spaces. 

Use the "↑" and "↓" keys to pan the camera forward or backward. 

Fly speed

In both modes, it is possible to adjust the speed of movement using the keys "", "" and "" or by using the "Flight Speed" panel (automatically visible when using Flight Mode or Walk Mode).

Tips: Measurements

There are two options that can be used in BIMcollab WebViewer to create measurements: (1) Laser Measurement and (2) Point to point measurement: 

 (1) Laser measurement 

This tool lets users place a point within the model, triggering three laser lines to extend towards the X, Y, and Z axes. If the laser line hits an object from both sides, then a dimension appears on the line and the line becomes solid, otherwise the line would stay as a dashed line and no dimensions would appear. 

For instance, in the example provided, a vertical section plane was used to view a room's interior. By positioning the laser point at the room's center, dimensions for the Z and X axes were revealed.

This laser pointer tool can also assist in measuring angles. Simply it should be placed on an angled surface, and it reads the degree of the slope.

 (2) Point to point measurement

This tool lets you measure the distance between two points. By default, measurements are taken perpendicularly, but you can temporarily disable this condition by pressing the shift key.
For instance, click on the surface of two opposite walls to learn the length of a building or click on the surfaces of the stair tops to know the height of stair cases. 

 Measurements can be removed by clicking on this icon.
