To exclude modifications of dimensions, position flags, weld marks or height indicators completely from being updated, you may protect them or set them free again. This is recommended for example for subsequent modifications of dimension texts or in the case dimensions were completely moved.

During automatic update of the 2D drawing, the program now checks whether e.g. a dimension has been protected. If this is the case, this dimension is kept exactly as it is and the corresponding „new“ dimension is deleted from the updated detail. The result may be that the position or the dimension text won’t match any more. Therefore, this option should only be used in the case you assume slight modifications (such as modifications of display or of position numbers) which only have few influences on the dimension.

Since in future versions keeping of modifications will become more and more efficient, this protection against update is only a temporary help, which will become superfluous again later. The adoption of modifications combined with the efficiency of the automatic mechanisms of ProSteel requires an enormous amount of time and energy in program development. This is the reason why modification management will only become perfect according to our requirements step by step.
