Tekla Structures 21.1 Sr1 Update With Help 33... ⚡

While updating from 21.1 to 21.1 SR1 does not change the model database, it is always wise to back up any models you are actively working on before applying any update. Models saved in a newer SR cannot be opened in an older SR of the same version, but they usually remain compatible across SRs of the same version.
