Revit has nearly 60 different ways to control object visibility. This visibility can be controlled by multiple compounding factors and new and experienced Revit users rarely remember to check all before asking for help.
Invisibility Advisor can discover the actual factors affecting an object’s invisibility. The tool offers advice to assist end-users understanding why the object(s) was not visible. In many cases, an instant ‘Fix’ option is available to have Invisibility Advisor attempt to resolve the visibility issue.
