Your work in a Revit project can be affected by the availability of system resources, such as physical memory, virtual memory, CPU load, and disk space. You can use the System Performance Monitor to monitor these resources.
If a resource reaches a predefined threshold, the Revit issues a notification.
To start the System Performance Monitor, click
on the
Revit toolbar.
To keep the System Performance Monitor window on top of other applications, select Keep System Performance on top. If you click outside the window to make it inactive, the window becomes smaller and semi-transparent. Click in the window to make it active again. The window expands to its full size.
To adjust the transparency of the window, select Keep System Performance on top, and change the value for Window transparency. A higher value results in a more transparent window. You can enter a value between 0 and 80. The default is 30%.
