Patent attributes
Certain embodiments include a computer-implemented method that includes receiving image data corresponding to a three-dimensional (3D) parametric model, receiving a selection of a scope of the 3D model, receiving a selection of one or more base lines for the scope, determining a slip type for the scope, calculating planes of the scope, calculating candidate dimension lines, selecting a dimension line of the candidate dimension lines based on dimension line placement rules, and displaying the selected dimension line adjacent to the scope that correspond to the selected one or more base lines. The calculated planes of the scope can be based on the one or more base lines and the slip type. The calculated candidate lines can be based on the calculated planes and dimension line placement guidelines.
