User Set

Collaboration requires identifying each participant to ensure that annotations and measurements are attributed correctly.

The host application configures user details using viewer.collaboration.setUser(...) after the viewer is mounted.

• username: A unique identifier for the user (required).
• displayName: The name shown to other session participants.
• email: Optional email address.

const result = await viewer.collaboration.setUser({
  username: "engineer_01",
  displayName: "Lead Engineer",
  email: "lead@project.com",
  timeoutMs: 10000
});

if (!result.success) {
  console.error("Set user failed:", result.reason);
}
