Hi Andrew: I received a solution yesterday from Bentley after going back and forth. I tried it and it worked The service request was 7000783609 Here is what they said: I have a solution from DEV team. There was a problem with images alignment, this is explained by the fact that the metadata of the images are not correct. The altitude values in the metadata are not good at all and that makes the AT can not find a good orientation: The scene will be bent, so the constraint will be shifted accordingly. To solve the problem one can place GCP by hand in order to recover a good georeferencing. The procedure is long and not very user friendly however: Create a block > Load images Submit AT while selecting Automatic Vertical as positioning mode > you will get a good orientation but the scene is not georeferenced. Open Google earth and ensure the following settings from Tools > options are enabled: Decimal Degrees for “Show lat/Long” and Meters for “Units of Measurment”. Now choose 4 relevant points then note their coordinates Go back in CC then click on Survey tab , Set the SRS to WGS84 + EMG 96 as Geoid then Create the 4 GCPs that corresponds to these points (report each of the GCP in 4 images at least) Now resubmit the AT and choose “ Use control points for rigid registration ” positioning mode You should have a scene that is georeferenced. Now you can apply a surface constraint. From Google earth, draw a simple polygon around the corresponding area. Once created, open properties of the polygon, click on Altitude tab and set the good altitude value as Absolute. You can see this value in the bottom-right side of Google earth. Here the altitude of the water is 75m. In CC, create a new reconstruction and import the constraint.
