A solution that automatically fine-tunes label locations in an engineering drawing is disclosed. The label locations are fine-tuned by performing a line-line solving process, a frame-frame solving process and a frame-line solving process according to a first order of the processes, and repeating performing the processes according to the first order as long as during performing the processes one or more frames have been moved to another location and a first repeat criterion is met. Each solving process repeats determining label pairs, and solving the problem in question for the labels in the pair as long as problematic label pairs can be determined and process-specific repeat criterion is met.
