When performing measurements of a point cloud profile there is no Frontview Profile table displayed at the bottom of the ERDAS IMAGINE workspace, only a Sideview Profile.
The Profile table displayed at the bottom of the ERDAS IMAGINE workspace will represent the profile view that was selected when you clicked the Measure Profile button. You can select the desired profile view by clicking its 2D View title bar. The title bar should change from gray to a pale yellowish color. If you had the Sideview Profile selected and clicked the Measure Profile button, the Sideview Profile table will display at the bottom of the workspace. To get the Frontview Profile table to display you have to select the 2D View with the Frontview Profile and click the Measure Profile button. You should now see two tabs at the bottom of the ERDAS IMAGINE workspace, one for Sideview Profile and one for Frontview Profile.
