We have discovered a critical issue in the recent November 2018 release version of OpenBridge Modeler CE, which we would like to bring to your attention.
Note: This issue also affects the OpenBridge Designer CONNECT Edition product line, which includes this build of OpenBridge Modeler.
When working with US/Imperial units, the slope and angle constraints for any deck are not being modeled accurately. This affects all bridge decks including P/S Girder Bridge type, Steel Bridge type, Segmental and CIP Box Girder. The slope constraint is incorrectly reduced by a factor of 3.28 before it is applied. So a 2% slope is actually modeled with a 0.609% slope, leading to incorrect deck elevations and affecting layout of all other bridge elements under the deck. As a temporary workaround, user's can input a modified slope, multiplied by a factor of 3.28 to workaround this issue.
We apologize for this error, and are working to fix and issue a new build. If you need further information, please contact our technical support team.
