The new Brazilian Synchrotron Light Source had its first friendly users late in 2019. During 2020, the first experimental stations were aligned and had the first beam successfully at the sample. The reference network of points used for the storage ring alignment was connected to an external network located in the experimental hall. Following this step, it was possible to extend these references to the hutches environment, where the beamlines components are installed. During the alignment of the first beamlines, a sequence of common tasks was performed, from the bluelining of the hutches footprints, to the components fine alignment. The position and orientation deviation of the main components will be presented for the Manacá, Cateretê, Ema, and Carnaúba beamlines. Two specific measurement strategies used for aligning special components will also be presented: (1) an indirect fiducialization procedure developed for most of the mirrors and their mechanisms using a mix of coordinate measuring machine and articulated measuring arm measurements, and (2) a multi-station setup arranged for the alignment of a 30 meters long detector carriage, using a mix of laser tracker, physical artifacts, and a rotary laser alignment system used as a straightness reference.
