A dimensioning system is provided for a computer generated model of a sheet metal
part including a plurality of entities. The dimensioning system comprises a model
display, an indicator, a selector, a dimension defining system, and a dimension
display. The model display displays a representation of the model on a display
screen. The indicator indicates to a user candidate entities of the model, in response
to user events, that may be selected. The selector selects two entities of the
model, based on an indicated candidate entity. The dimension defining system defines
each dimension associated with the selected entities of the model. The dimension
display displays dimension information on the display screen based on the defined
dimension. A repositioning system is also provided for a computer generated model
of a sheet metal part represented on a display screen. The sheet metal part has
associated dimensions displayed along with the sheet metal part on the display
screen. The repositioning system comprises a repositioner and a repositioned dimension
display. The repositioner repositions the dimension to a desired position relative
to the model. The repositioned dimension display displays the dimension at the
desired position relative to the model.
