Viewer Options

Hi, viewers cannot create things as far as I know.

They can only use the "temporary" dimension tool. Meaning they can take a measurement on a scaled sheet, but the measurement disappears once they click the second point.

Can there be the option for them just to do annotation as a viewer?

We have many feature requests asking for specific permission changes for specific people on specific pages/projects. Permission customizations are on our roadmap but not available at the moment.
