How to use the Commenting Tool

The Commenting Tool allows you to create topics and add comments to selected locations - in real-time. Tridify supports BCF; you can open the BCF file in the Viewer, add new comments and then export the BCF file.

BCF (BIM Collaboration Format) allows different BIM applications to communicate model-based issues with each other.  You can create topics and add comments in the Tridify BIM Viewer and save them as a BCF file, or import a file created in other software.

Comments imported from the BCF file and comments created with the Commenting Tool are attached to the BIM Viewer link. The link can be shared and those with the link can create new topics and add comments. 

Please note that the Commenting Tool is only accessible in the Viewer if the tool is selected when publishing the Viewer.

In the Tridify BIM Viewer, click the Commenting Tool button to turn on the tool.

The created topic can be deleted as long as the current Viewer session is open.

Viewing comments

Tridify BIM Viewer's Commenting Tool provides a way to communicate in real-time. New topics and comments created by other users are marked with a red dot.




You can move from one topic to another by clicking on the small comment icons...




...or by clicking the back and forward buttons in the Comment window




Click x to close the Comment window.




To view the list of topics, click the Comments list button. Clicking a topic in the list opens the topic and takes you to its location.



Using the BIM Collaboration Format

Topics created in other software can be opened to the Tridify BIM Viewer using BCF. The imported new topics will be added to those already present in the Viewer. Make sure the IFC file in the Viewer is the same as that used to create the BCF.

To open a BCF file in the Viewer, open the Comments list window and click Open BCF.




Topics imported from a BCF file can be viewed in the Tridify BIM Viewer and new topics and comments can be created.

You can download a BCF file with all the topics and comments for use in other software. To save the file to your device,  open the Comments list window and click Download BCF.




Filter topics

Use filtering to view specific issues. Filtering is most useful when a BCF file is imported into the Viewer. In the Comments list, click the Filter issues button.




You can filter issues by status, label, assignment and type. Select the desired filters and click Apply filters.



Hide comments

You can hide all the comments in the Viewer by clicking the Commenting Tool button. Comments reappear when you click the Commenting Tool button again.

Note that when you delete the Viewer or the uploaded IFC file, the comments are deleted. Downloaded BCF files remain intact.
