New Update LARS Bridge v5.00.06.06 available on SELECT Server

LARS Bridge General Enhancements and Fixes

  • LLDF Cross-Section Description dialog now applies to each member instead of each bridge.   This will allow a User to define different beam spacing and roadway width for each member.  There is no visible change in LARS Bridge for this enhancement.   Any existing files with data in the LLDF Cross Section Description dialog  should be saved in LARS Bridge v5.00.06.06 so that LARS Bridge will convert the dialog data from a per structure basis to per member basis.  Save the file by either using the save icon from the toolbar as shown below.                

                            

             Or by using FileèSavefrom the File menu as shown below.
