scoring a fold-line in a location based at least in part on that a distance of that location from at least two edges.

4. The method of claim 1 , additionally comprising:

scoring the piece of cardboard based at least in part on measurements between edges of the piece of cut cardboard;

folding the piece of cardboard based at least in part on measurements performed after the scoring of the piece of cut cardboard; and

gluing the tab to the panel based at least in part on measurements performed after the folding.

5. The method of claim 1 , wherein measuring the knocked-down case comprises:

measuring between a fold and an edge;

measuring between two edges; and

measuring between two folds.

6. A method for knocked-down case manufacture, comprising:

cutting a piece of cardboard according to a shape of a knocked-down case to thereby form a cut piece of cardboard;

measuring a first plurality of distances between edges of the piece of cut cardboard;

scoring the piece of cut cardboard to create a plurality of fold-lines, wherein locations that are scored are based at least in part on the first plurality of measured distances;

measuring a second plurality of distances between scores and edges of the piece of cut cardboard;

folding at a fold-line between a major panel and a minor panel to thereby create a fold, wherein the fold is made based at least in part based on the second plurality of measured distances;

measuring a third plurality of distances between the edges of the piece of cut cardboard, the plurality of fold-lines, and the fold between the major panel and the minor panel;

folding at a fold-line of a tab of the piece of cut cardboard, wherein the fold is made based at least in part based on the third plurality of measured distances; and

gluing the tab to a panel of the piece of cardboard to form a knocked-down case.

7. The method of claim 6 , additionally comprising:

measuring the knocked-down case; and

sending the measurements to a case-erection system.

8. The method of claim 6 , additionally comprising:

measuring the knocked-down case; and

printing indicia on the knocked-down case, wherein the indicia comprise information about one or more measurements.

9. The method of claim 6 , additionally comprising:

measuring both sides of the knocked-down case; and

printing indicia on the knocked-down case, wherein the indicia comprise information about one or more measurements.

10. The method of claim 6 , additionally comprising:

measuring an angle of orientation of corrugations in the piece of cardboard; and

rotating the piece of cardboard, if indicated by the angle of orientation, to orient the corrugations of the piece of cardboard to a specified orientation.

11. The method of claim 6 , additionally comprising:

determining, after each measuring step, if the knocked-down case can be successfully completed; and

discarding the piece of cardboard if the knocked-down case cannot be successfully completed.

12. The method of claim 6 , additionally comprising:

determining, after measuring the first plurality of distances, if the knocked-down case can be successfully completed;

determining, after measuring the second plurality of distances, if the knocked-down case can be successfully completed; and

determining, after measuring the third plurality of distances, if the knocked-down case can be successfully completed.

13. A method for knocked-down case manufacture, comprising:

cutting a piece of cardboard according to a shape of a knocked-down case to thereby form a cut piece of cardboard;

scoring the cut piece of cardboard to create a plurality of fold-lines;

folding at a fold-line between a major panel and a minor panel to thereby create a fold;

folding at a fold-line of a tab of the cut piece of cardboard;

gluing the tab to a panel of the cut piece of cardboard to form a knocked-down case;

measuring the knocked-down case to obtain measurements, wherein measuring the knocked-down case comprises:

measuring a height and a length of the major panel;

measuring a height and a length of the minor panel;

measuring a height and a length of upper and lower flaps for the major panel; and

measuring a height and a length of upper and lower flaps for the minor panel; and
