Software Compatibility

Model and results files created by LUSAS Bridge LT can be read by other LUSAS Bridge software products. Model and results files created by LUSAS Bridge and LUSAS Bridge plus versions can be opened for editing or viewing in LUSAS LT provided the model contains only those elements and analysis options supported by the LT version.
