This paper describes a computer program that performs semi-automatic modelling of disordered moieties in SHELXL [Sheldrick (2015). Acta Cryst. C71, 3–8.]. The new program contains a database that includes molecular fragments and their corresponding stereochemical restraints, and a placement procedure to place these fragments on the desired position in the unit cell. The program is also suitable for speeding up model building of well ordered crystal structures. %U http://resolver.sub.uni-goettingen.de/purl?gldocs-11858/6687 %~ FID GEO-LEO e-docs
