How to use the Commenting Tool

The Commenting Tool allows you to add comments and replies to selected locations - in real-time. Tridify supports BCF (BIM Collaboration Format); you can open the BCF file in the Viewer, add new comments and export the BCF file.

Comments created with the Commenting Tool are attached to the BIM Viewer link. The link can be shared and those with the link can reply to comments and add new ones. 

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

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.



Navigate to where you want the comment to appear and click the + button to create a new comment.

You can attach objects to a comment (optional). Attached objects appear in the Issue details tab of the Comment window and are highlighted in the Viewer each time a comment is selected.

Click Attach objects.




Select one or more objects. The selected object is colored with the color selected from the menu on the left. If you select the wrong color or object, click the object again to remove the selection. The color added to the object is displayed whenever the comment is viewed.
