redline

Mobile app users and Web Central users can add redlines to drawings to make notes about an area on the floor. For example, redlines might show a change that needs to be made to the drawing, or can clarify the location of an issue, such as an area needing maintenance work.

Once you redline a drawing in Web Central or mobile, other users can access it as a document. For example, as a service desk requestor, you might add redlines to a CAD drawing that show a problem location. Other users approving or servicing this request can then view your comments using the service request's Document field.

In Web Central, you will notice that there are two forms of redline tools:

Beginning with ARCHIBUS V23.2, all Web Central views use the HTML drawing control. These views might include redlining as part of their markup tools.
You might have custom views that use the older Flash drawing control, which provide a toolbox of arrows, text boxes, lines, and so on. Views that use the Flash drawing control do not allow redlining on images.

The HTML redlining feature is also used in mobile apps.
