The invention relates to a method for determining material dimensions of a longitudinal profiled section (2) during a sawing process, in which a saw blade (3) is advanced, the longitudinal profiled section (2) being machined by said saw blade (3) along a saw groove during this time; advancement position data of said saw blade (3) along the advancement path (s) being determined and, during this sawing operation, additional measurement data being determined from the group of sawing force (F.sub.s) or another variable which corresponds to the sawing force (F.sub.s). The invention is characterised in that an actual profile is determined from the advancement position data and said additional measurement data.

A method and apparatus for protecting a structure. A surface of the structure may be identified from a model of the structure. A perimeter of the surface of the structure may be identified from the model. The perimeter may be identified for the surface of the structure to be covered by a masking system during painting of the structure. A two-dimensional representation of the masking system may be generated for the structure based on the perimeter of the surface of the structure. Features for the masking system may be generated within the two-dimensional representation. Identifiers may be assigned to the features in the two-dimensional representation. Instructions for a forming tool may be generated based on the identifiers. The masking system may be formed from a sheet of masking material using the forming tool based on the instructions.
