BIM Collaborate Products basic tasks for preconstruction and model coordination
Understand how to coordinate your design models using clash detection and issues.
Create a coordination space
Use coordination spaces to automatically detect clashes among models. You can define them by selecting Model Coordination > Product Settings. Alternatively, you can define them when you create team spaces in Design Collaboration.

When you find a clash, you have two choices. Ignore it by verifying that it's not an issue, or resolve it by creating an issue for the team to review and address.
