FAQ: Why is my viewport not updating properly?

Under certain circumstances, such as when you switch view directions in shade modes other than 2D wireframe, the display is not restored correctly.

In such cases, click View tabAppearance panelRegenerate drop-downRegenerate Model, and either select the problem AEC object or press Enter to select all the AEC objects. This forces the display system to regenerate all the current display representations.

Note: Alternatively, enter OBJRELUPDATE on the command line.
